aaah, no clue whats wrong here: 0:26.17 c:/devel/myUXP/intl/icu/source/i18n/messageformat2_function_registry.cpp(862): error C2280: 'icu_78::message2::StandardFunctions::Plural::Plural(const icu_78::message2::StandardFunctions::Plural &)': attempting to reference a deleted function 0:26.17 c:\devel\myuxp\intl\icu\source\i18n\messageformat2_function_registry_internal.h(248): note: compiler has generated 'icu_78::message2::StandardFunctions::Plural::Plural' here 0:26.17 c:\devel\myuxp\intl\icu\source\i18n\messageformat2_function_registry_internal.h(248): note: 'icu_78::message2::StandardFunctions::Plural::Plural(const icu_78::message2::StandardFunctions::Plural &)': function was implicitly deleted because a data member invokes a deleted or inaccessible function 'icu_78::LocalPointer<icu_78::message2::StandardFunctions::Number>::LocalPointer(const icu_78::LocalPointer<icu_78::message2::StandardFunctions::Number> &)' 0:26.17 c:\devel\myUXP\intl\icu\source\common\unicode/localpointer.h(343): note: 'icu_78::LocalPointer<icu_78::message2::StandardFunctions::Number>::LocalPointer(const icu_78::LocalPointer<icu_78::message2::StandardFunctions::Number> &)': function was implicitly deleted because 'icu_78::LocalPointer<icu_78::message2::StandardFunctions::Number>' has a user-defined move constructor and v141_xp seems to be not good enough to build ICU 78. EDIT: got it fixed, -std:c++17 is needed by new ICU, so vc2015 branch will no longer be buildable as ICU can't be skipped.

I think I can make a special release tomorrow! And now I have a newer-than-mypal ICU and feodor2 may have a look?

Generally, Panda Antivirus Free is working under Windows XP, even in the most recent version. However, there are two issues. The first issue which I noticed is the unability to connect to a Panda Dome account. Every time you open the programme interface, you are annoyed by a pop-up window asking you to log in to a Panda Dome account. However, this does not work under Windows XP and ends with an error message. There is no official solution for this error. But I have a solution. It appears to be a TLS problem. A secure connection is required, which Windows XP cannot establish natively. The solution is ProxHTTPSProxy, HTTPSProxy or ProxyMII which you can get in my thread Simply set the proxy in the Panda Antivirus settings and set up your Panda Dome account. Once this is done, Panda will no longer bother you, and the proxy settings can be deleted again. The second issue consists of a delay of several minutes during system start-up. Panda Antivirus needs round about 5 minutes to be completely loaded on my machine. I tried different versions and possible solutions, but nothing helped. Therefore, this issue has been reported by me to Panda's support. We will see what happens. Greetings from Germany, AstroSkipper

There are now (at the end of 2025) very, very few anti-malware programmes for Windows XP with real-time protection free of charge. Panda Free Antivirus is an absolute exception. It is still maintained and runs under Windows XP. Here are two screenshots of the current version 22.03.05, which has just been released: An anti-malware programme with a most recent scan engine and up-to-date virus definitions even under very old OSes like Windows XP or Windows Vista. What more could be wanted? Here is the link to my updated article: Cheers, AstroSkipper

Apparently, I'm not the only one who has noticed such abnormal delays when starting up Panda while system start: 16 minutes! That's record-breaking. Any other here observing similar issues?

If you encounter problems installing Panda Antivirus Free and uninstalling it fails or is incomplete, you should use the Panda Dome Generic Uninstaller, which is available here: https://techsearch.pandasecurity.com/PandaKBView?id=kA1Vr00000064QjKAI

Microsoft .NET Framework 4 is needed and should be installed to ensure that Panda Dome runs correctly.

Ran into a small problem after downloading your 'offline installer' download. I got offline to run the download and found out that I need to have .NET Framework also installed. I did have .NET Framework 2.0 installed years ago but removed it. Didn't seem to have much use for it on Win XP at the time. If there were any programs that might require it I was always able to find another program that didn't need .NET Framework to run. I have all the .NET Framework versions that worked on XP stored on a DVD backup with other old Win XP programs ... in case needed one day. I think at the time .NET Framework 3.5 was the last version to work on XP but after getting back online to search around I now see that there is a .NET Framework 4.0 that will install on Win XP SP3. I have now downloaded that version but I may just try .NET Framework 2.0 first out of curiosity and see if that works. If not then I can jump to version 4.0. That version from MS is dated from last year: 07/15/2024 ... I will put the MS link here in case someone else has need for it. Microsoft .NET Framework 4 (Standalone Installer) https://www.microsoft.com/en-us/download/details.aspx?id=17718 Date Published: 07/15/2024 Supported Operating Systems: Windows 7, Windows 7 SP 1, Windows Vista SP 1, Windows XP SP 3 Windows XP SP3 Windows Vista SP1 or later Windows 7 Windows 7 SP1 Supported Architectures: x86 x64 Thanks ...

I was able to login in with OAth2 using MailNews with an outlook account. I had to go in the config editor and set *general.useragent.compatMode.firefox* to true. Then the Microsoft login page displayed properly and worked. Hope it helps some folks, I am using windows server 2003

AstroSkipper ... Just came across you're updated information dealing with Windows XP and Panda Free Antivirus. Around two weeks ago I was actually looking for any antivirus programs still working with WinXP in 2025. Didn't find any after doing a quick search on some programs that worked many years ago and reading your earlier post on the subject. Thanks again for the update on this valuable information for Windows XP users. ...

This thread is about anti-malware programmes under Windows XP. BTW, there is definitely no need to use an "ancient version of whatever" under Windows 10. And talking about your "ancient version" is like "beating a dead horse". A version of this programme running under Windows XP has not been available for a long time. And it gets even worse: the programme is not secure, and its country of origin is beyond good and evil. In my next article, I will post something current for Windows XP.

Personally, I don't expect modern websites that are full of multimedia or completely overloaded to still run in UXP browsers under old OSes like Windows XP, but I am happy about those that still do. All others are called up by me under Android 10 and above. That's why I'm extremely relaxed about the whole thing. The more websites running in New Moon or Serpent, the better, but if not, then that's just the way it is.

I have now installed fltmgr.sys build 5107 also under WinXP SP3 on my i7 desktop computer, by booting into Win10 and then copying fltmgr.sys onto the WinXP partition. fltmgr.sys build 5107 works fine on the 3.4GHz i7 desktop under WinXP SP3 and WinXP feels a little crisper The updated fltmgr.sys is a must-have for slow computers under WinXP, and a nice-to-have for WinXP on fast computers. The remaining question now is: Which build of fltmgr.sys is the best one for WinXP SP3?

info here It states that : Sometimes Microsoft released builds referred to as “Escrow”. Escrow means the development of a branch gets stopped and the code is being tested. If Microsoft or its testers don’t discover any serious bugs (“showstoppers”), the current build becomes the final milestone (usually RC or RTM, but sometimes there are also beta escrow builds). Escrow builds are usually handed out to TAP (Technology Adoption Program) testers, ISVs, IHVs, etc. http://www.windowswiki.info/2010/01/10/what-does-idsidw-mean-and-what-are-escrow-builds/

Notice: upstream pushed a big ICU update, and I may need to further look at the changes to see if any new changes are needed for our old target platforms, currently no ETA for upcoming new builds.

Apparently, I'm not the only one who has noticed such abnormal delays when starting up Panda while system start: 16 minutes! That's record-breaking. Any other here observing similar issues? Until Panda fixes this bug, I will avoid using the latest version 22.03.05. When starting my Windows XP computer, I am not prepared to accept lazy compromises. The start-up process must run smoothly as I always managed in the past. Panda offers two different installers, one of which is a "legacy" one. This installer does not solve the delayed start-up problem either. All 22.0x.0x versions have start-up problems on my computer. Especially the PSANHost.exe process leads to a full utilisation of the system during computer start-up. During my tests and investigations, I have now also looked at older versions. One of these seems to run much better, with a start-up behaviour that appears almost normal. Let's see if this proves to be true over the next few days.

it is fine as long as DLLs are newer than 3 Dec, as I don't rebuild whole thing.

Indeed. I have the KB4512788 (x86 for Win2003 Server); it contains fltmgr build 6912 and all 4 kernel HALs again and also kernel. This fltmgr works in XPSP3/uSP4, but hitches even more than 5107... If this thing would work normally in XP, it is a much better experience because it isn't maimed like the XPSP3_fltmgr_build5512 is. When it works, the system feels much more robust as WinNT always used to feel when coming from / dual booting 98 and NT4 and NT5. Now XP just because of this one very low level component feels like Windows 98. But hey, it's all we've got so it'll have to be enough until someone backports a proper fltmgr for it.

Even today, the proxies ProxHTTPSProxy, HTTPSProxy and ProxyMII have lost none of their importance for Windows XP. There are programmes that still run on Windows XP but require a secure TLS connection. A good example of this is Panda Antivirus Free, which requires such a connection to activate the user account, albeit only once.

FWIW, .NET FW 4.0 isn't a replacement for older .NET frameworks; 2.0/3.5/4.0 can co-exist on the same machine, and each one caters to applications targeting that specific version of .NET FW; i.e., if an app was built against 2.0, it needs 2.0 installed to run; likewise for newer apps built against 4.0... On Vista and later Windows versions, a newer 4.*.* version will overwrite a previously installed 4.*.* version of .NET FW, however this is NOT applicable to XP SP3, where only 4.0.x was made available; loyal XP users here can chime in to assist you, but from memory I recall than some feature/security updates for .NET FW 4.0 were made available at the time for XP SP3; unless the (recent) installer you linked to has those bundled ...

Thanks for this tip! Finally, a working login form appears. Unfortunately, a login into a personal Outlook email account is not possible. Only for school or work accounts. Thank you, Microsoft!

I was having many problems with Mypal68 74.1.2 shutting down on many websites ... after updating to Mypal68 74.1.3 in early December, all those problems have gone away. Mypal68 74.1.3 is very stable for my WinXP system with only a 'very rare' shutdown. I also use New Moon but it has problems with some websites. Mypal68 74.1.3 has now become my main WinXP daily browser. Thanks for your work and this newer update. ...

I don't think so, KB3072630 is an update of MSI Installer of 2015.

yes it is always an issue because GetLogicalProcessorInformation is missing in XP SP2. you may either update kernel32.dll with that API available(i.e. WindowsXP-KB936235-v2): http://kmeleonbrowser.org/forum/read.php?19,143253,page=10 or patching your target application with kernelxp and patchk32. https://github.com/roytam1/rtoss/tree/master/kernelxp a patched SP52 running on just-installed XP SP2 VM: or unpatched SP52 build on WindowsXP-KB936235-v2-x86-ENU installed XP SP2 VM:

I suppose your investigation results are quite valuable to XP SP3 users on old and under-resourced H/W; so, thanks for your time spent ; however, unless one had downloaded to disk v21.01.00 when it was still current, it's now a real task to find working/valid links to actual (off-line) installers to it ; I did a simple G-search for it and ALL results on pages 1-3 point to (mostly) stub or off-line installer-links hosted on the vendor's (PANDA) servers; but these tend to download the latest version of the software, not the older one we're after ; I did succeed in the end in finding links to offline installers for v21.01.00, but these were self-hosted on Iranian and/or Russian sites, so, as you can understand, I won't share them publicly here ; other than that, is there a special setting one should configure in v21.01.00 so that it doesn't auto-update to a more recent version? FWIW, v23.00.00 has now become the latest (digitally signed 22/12/2025) ... Kindest greetings.

I can't tell whats wrong on your side but it is working here.

I'm sorry, somehow I thought I'd just normally decompress them instead of installing them. :-) Since MilkChan has built those fine update packages, I'd say SSE (b5107) for slower computers and SSE2 (b6912) for faster. Could you please test both and see which is faster. I think b5107 might be faster (it is also the last build in non-ESU fully updated Server 2003 x86).

New build of post-deprecated Serpent/moebius for XP! * Notice: This repo will not be built on regular schedule, and changes are experimental as usual. ** Current moebius patch level should be on par with 52.9, but some security patches can not be applied/ported due to source milestone differences between versions.

The counter has not been working since maintenance in October. Perhaps simply disabled.

I have accelerated my tests and investigations and now finally finished. And what I already mentioned in my previous post, has now actually been confirmed: an older version of Panda Antivirus Free is the solution. Panda Antivirus Free 21.01.00, the last version (from October of 2022) before the 22 series was released, runs smoothly under Windows XP without the annoying delay at system start-up. The main culprit of all versions 22.0x.0x is the process PSANHost.exe which does not run properly, leads to a full utilisation of the system during computer start-up, a very long delay and unsightly disturbances during other operations after completion of loading. Therefore, my current recommendation is to use Panda Antivirus Free 21.01.00 on Windows XP instead of the latest version, which is currently 22.03.05. At least, until the manufacturer provides a fixed version. I have informed the Panda support in detail but don't know if they will ever react. But I do hope so. In any case, my Windows XP computer needs now again less than 2 minutes for system start-up without any unsightly disturbances during later operations. So once again, the old rule applies: the latest is not always the greatest. Merry Christmas to all, AstroSkipper

Update. I still cannot do a screencap yet (new computer does not get internet connectivity until *after* I get the OS rebuilt to my "liking"). I installed Supermium v126 R7 inside a Win10 VM on my new Intel Core Ultra 7 and Supermium v126 does *NOT* have the font-indent issue. This issue is DEFINITELY hardware-related and it has ALWAYS existed (all versions of Supermium except maybe the most recent) on my 17/18yr old Intel Core2 Quad Q6700. And yeah, bad habit, but I always reference my computers by their CPU and not their GPU. I kind of doubt that I will bring the Q6700 back to life just for the sake of a font-indent issue screencap on old-versus-new Supermium. A font-indent issue that was present both "direct" and "inside a VM" on the Q6700 but does *not* effect (affect?) my new hardware.

I have five different installations of Supermium, x86 and x64, on different machines and operating systems, Windows XP and Windows 10. FWIW, I have never been aware of any problems with fonts on any of them.

I tested the new Chromium on Win XP. It runs faster than Supermium. But there are a few things to note. The RAM consumption bug when C++ is installed can be resolved by adding the corrected_api_sets.zip folder from Supermium. In XP x64, there is enormous virtual memory consumption, and I haven't found a solution. WebGL is completely disabled, even the software version, which means that websites that require it do not work. Manifest v2 is available but disabled by default. You need to add the parameter --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled to the shortcut. To disable the notification that the OS is not supported, add --test-type to the shortcut. The browser requires a CPU with SSE3. Browser crash during import fixed in version 144.

Hello, as you are probably aware, Windows has problems with long paths (total length > 260 characters). --- In old Windows versions there is the "\\?\"-trick, which helps in a few situations: --- Starting with Windows 10, it is possible to allow specific applications to use longer paths. According to the documentation, Microsoft modified specific functions of the API to allow using longer paths for specific applications in Windows 10. So the list of functions is rather interesting. And here it is: CopyFileW CopyFile2 CopyFileExW CreateDirectoryW CreateDirectoryExW CreateFileW CreateFile2 CreateHardLinkW CreateSymbolicLinkW DeleteFileW FindFirstFileNameW FindFirstFileW FindFirstFileExW FindFirstStreamW FindNextFileNameW FindNextFileW FindNextStreamW GetCompressedFileSizeW GetCurrentDirectoryW GetFileAttributesW GetFileAttributesExW GetFinalPathNameByHandleW SetFileAttributesW GetFullPathNameW GetLongPathNameW MoveFileW MoveFileExW MoveFileWithProgressW RemoveDirectoryW ReplaceFileW SearchPathW SetCurrentDirectoryW --- Is anyone aware of any pioneer work that has been done to improve the situation with Windows versions older than Windows 10?

The restriction you addressed in the FAT32 file system and the NTFS file system is probably the most difficult part to solve. Since these 2 file systems allow no object names (folder names or file names) longer than 256 characters, it will be a problem storing longer names if the file system driver prevents it. Your suggested solution to shorten long object names leads to truncated names and looses the uniqueness of the names. Once a name is shortened the truncated part is lost and we might have 2 folders or 2 files with the same name. --- There is an easier part where at least some progress can be achieved: Some of the functions restrict the caller to max_path for the total path name (not the object name), even though there doesn't seem to be a good reason. So it might be the case, that these restrictions can be lifted. However, some functions return a path and the caller might provide a buffer, that can take no more than max_path characters. These functions are more problematic, because we don't want to create buffer overruns. Here is the list of functions, which don't return paths: CopyFile2 CopyFileExW CopyFileW CreateDirectoryExW CreateDirectoryW CreateFile2 CreateFileExW CreateFileW CreateHardLinkW CreateSymbolicLinkW DeleteFileW GetCompressedFileSizeW GetFileAttributesExW GetFileAttributesW GetFullPathNameW GetLongPathNameW MoveFileExW MoveFileW MoveFileWithProgressW RemoveDirectoryW ReplaceFileW SetCurrentDirectoryW SetFileAttributesW Here is the list of functions, which return paths: FindFirstFileExW FindFirstFileNameW FindFirstFileW FindFirstStreamW FindNextFileNameW FindNextFileW FindNextStreamW GetCurrentDirectoryW GetFinalPathNameByHandleW SearchPathW --- Well, if you are talking about KernelEx for Windows 98 and Windows Millenium, we might also consider looking into the slim-character versions of the functions (for example RemoveDirectoryA) and not just the wide-character versions (for example RemoveDirectoryW). I don't know a good reason, why long paths should be limited to a specific character set used.

Hi! It's been awhile since I posted here! I'm mainly using Mac OS nowadays, but I still maintain a Windows 7 VM, and I have a Dell OptiPlex 7050 running Windows 7 Professional that I use for playlist automation (I run a small, unlicensed AM radio station; the neat part is that it's not illegal: look up Title 47, CFR Part 15, Subsection C, § 15.219 of the FCC rules). So, despite it being over 16 years old now and EOS since 2020, it's still perfectly usable and secure enough to at least get done what I'm trying to do, as you can see here: I had an earlier version of this running on XP, but unfortunately, it got too old to run the versions of the above apps I wanted (clockwise from top left: Butt, PlayIt! Live, Stereo Tool). 7 is still in that sweet spot where current versions of these things are still supported, so I'm going to use it while I still can (that said, I'm planning for an eventual upgrade to (ugh!) Windows 10 because, unfortunately, the fun doesn't last forever, and there's no Mac or Linux version of PlayIt! Live). Here's to keeping Windows 7 alive, one PC at a time! c

I'm down to one active computer using Windows 7, the one I am posting from. I do all of my daily driving with it and every site I need to use still works. My old Win7 is still connected but it stays off most of the time. That computer was the one that used to be my daily up until the end of June and was the one that I had posted about in the Uptime and HD Reliability threads.

@Monroe Actually, uBO 1.62 is compatible with FF78 and up. And uBO 1.65 is compatible with FF92 and up. But as @feodor2 wrote, one can't rely on version numbers in Mypal anymore, it is now a mix of different ones. So, only trial and error is the game. Personally, I prefer uBO 1.62 at the moment since I don't want to go too far away from FF68 or FF74. Who knows what would be missing if you moved too far away from FF68 in terms of compatibility. OTOH, do not think if something is compatible with FF68, it has to work in Mypal. That's water under the bridge. Think, for example, of the Nuchi-Sporif script loading method which no longer works in Mypal! P.S.: This and the last few posts are an exception. Everything concerning extensions, custom buttons, CSS stylesheets or UC.JS scripts and their loaders in Mypal will be dealt by me with in this dedicated thread: I personally consider this thread here for the Mypal browser itself. At the moment, my favourite version of Mypal is 68.14.8b.

Supermium ==> Supremium Someone, suggest to win32. I'm not gonna charge for this name.

Excuse me for a slight off-top. How did you manage to do it ? As far as I know , the later updates won't install without a proper ESU licence. They just "configuring" endlessly. "If you are installing this update on a device that is running an edition that is not supported for ESU." Like this one , see : known issues. https://support.microsoft.com/en-us/topic/august-10-2021-kb5005095-security-only-update-a324fdbb-ce90-4c4d-8d9d-e9f2f2a57e0e

Totally agree ! Having no taskbar sux . That's why I still hope you bring us the new 13.6 .

You are effected by error code 0x80072EFE too. It's not only 0x80070002, it's just the final output.

I don't believe that this has an effect. In my system I have same date and time format in this key although my regional settings have been set to German DE and nonetheless MU is working flawlessly. @Dave-H Any news? Does changing services mode have any effect? Here is another change to Internet Options of IE, Advanced: unselect "Check for publisher's certificate revocation" too. Note: in my system it is selected at the moment. The entry "Check for server certificate revocation" should already be unselected in any case.

No problem but a little bit funny. Read post above!

@Dave-H The first entry is related to ProxHTTPSProxy and the second one to HTTPSProxy. You know I have both in my system. I found a list with all error codes. Here is the link: http://inetexplorer.mvps.org/archive/wuc.htm And there you can find: Error Code: 0x80072F8F Dec Error Code: -2147012721 Error String: ERROR_INTERNET_SECURE_FAILURE ErrorClockWrong Description: One or more errors were found in the Secure Sockets Layer (SSL) certificate sent by the server. I wanted to upload more screenshots but I have a size limit of 45 kb. No chance! Is that normal?
