Those builds are originally for my private use and they are released because of my goodwill that I think they may help others. This bug doesn't affect me and so I don't have big intention on hunting and fixing it. If you want this to be fixed you at least need to find when the problem started to occur. and last but not least, stop gaslighting.

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. EDIT2: the above error is solved by adding a copy-ctr line in localpointer.h, all changes are in https://github.com/roytam1/UXP/commit/9f6727874f81bf98ef3f54f046d14c6c5cfdc20f , and hope I did it right. 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

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

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

Notice: although there are some commits in upstream which worth importing, I'm mentally affected by fire news happened in Hong Kong lately so new build will be delayed (i.e. no build this week)

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:

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 ...

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.

https://github.com/e3kskoy7wqk/Chromium-for-windows-7-REWORK He made few reworked versions. It also can support XP and Vista without extended kernels

I didn't realise there were so many still using SP2 (why?). I will consider building the next version with PyInstaller 5.13.2 again. But do note, that in the future that may not be possible any more, due to the changes they make. Consider upgrading to SP3. In the meantime, here is a build that should work on SP2. @davidz, Do you really mean you're on SP3?

@Goodwin @roytam1 I'm not a professional, I just compile Mozilla based browsers for my personal use and hope for the best. For instance, I'm trying to compile Firefox 13+ with Windows 2000 compatibility. One thing that sometimes (but not always) causes runtime execution failure is clicking on tools -> options -> applications which can cause an error in MSVCR71.DLL. Also, after reverting the commit that broke Windows 2000 compatibility, I had a minor problem that is caused by opening a new tab, and the message displayed on the new tab page was relating to an invalid address. That annoyance was caused by the commit for Mozilla bug 728429, which mandated ASLR on Windows. In order to find that, I had to cherry-pick a range of commits between the one that broke Windows 2000 compatibility, and the one mandating ASLR, then compile the source code a few times to narrow down my search. The point is, if a problem does not exist in one of roytam1's browser builds, then exists on a later browser version, the right thing to do is find out what the last good version, and the first bad version is, then it would be easier to find when the problem started, and what commit caused it. Also, it is possible a bug might not affect everybody.

If you ***REALLY*** want your video playback looked into, it's kind of ON YOU to do some LEGWORK in NARROWING IT DOWN. *Shoot the messenger* all you want. But that really is the reality of the situation. We (you!) need to tell roytam "playback WORKS in this month-day-year release, but it is BROKEN one week later with the month-day+7-year release".

Notice: seems need some more time on ironing out front-end (win11) related revs from upstream which hopefully can be done in xmas, but UXP related changes are in and hopefully new build (without those front-end changes) will be available this week.

Reviews: "Panda's ability to catch malware lags behind that of many other free security products," from: https://www.tomsguide.com/us/panda-free-antivirus,review-3524.html "Its security scores may not be consistently impressive" from: https://www.techradar.com/pro/security/panda-dome I was also surprised at the score of 6/100. I initially thought that I had a wrong setting in Panda. The 100 files in my sample were from actual downloads from eMule, together with many good, clean files. I have two 2TB HDDs with flagged stuff from eMule, and could have increased the sample size to 10,000 infected files from eMule, but an initial check with 100 randomly picked infected files was good enough for me. I only wanted for myself an initial glance at the approximate detection capability of stuff from eMule, which may be different from the results of official tests by the professionals.

Thanks. I first installed MS .NET Framework v4.0 (18Mar2010) under WinXP SP3. Then I installed OK Panda Dome v21.01.00 under WinXP. I selected "Offline installation" during installation. I have not yet activated the program because activation requires entering an email address. After the first run the Settings window indicates "Last updated 12/26/2025". First the good news: Panda Dome v21.01.00 runs OK under WinXP on my old Inspiron 7500 (700 MHz Pentium III, SSE-only). The program does not seem have a conflict with other programs installed. Kerio Personal Firewall v2.1.5 has no issues with the program. It is even possible to run My Ancient version of Kaspersky simultaneously with Panda Dome, no conflict. Now the bad news: I made a virus-check with Panda Dome v21.01.00 of "My personal in the Wild", which is a collection of 100 infected files downloaded with eMule. I had prepared this collection a year and a half ago for testing-purposes by taking at random 100 files from a HDD full of infected downloads from eMule. Panda Dome v21.01.00 flagged only 6/100 files [msg: 8,531 scanned, 7 detected, i.e. 1 file was flagged twice, because of multiple infections], Only 6 files were quarantined, and 94 infected files were left as "clean" in the folder \My personal in the Wild_6Jul2024\ For comparison: When I ran My ancient version of Kaspersky with this test set of 100 infected eMule files, Kaspersky scanned 171,873 files contained in the various .rar, .zip, .exe etc in \My personal in the Wild_6Jul2024\ and, detected 167 viruses, trojans etc. 99 files were cleaned, the single file which was flagged but not cleaned was a .rar file containing in turn infected multi-part .rar files. Panda Dome v21.01.00 does NOT install under Windows Server 2003 SP2. When I tried to install it under Win2003 SP2 I got the incorrect error message: "You must upgrade your version of .NET Framework". Panda Security apparently did not prepare a recent corporate edition for Windows Server, maybe no demand. Kerio Firewall flags a file named "TUNNEL.EXE", which has to be given permissions. Which IT-Manager would be inclined to license software which opens a tunnel into corporate computers? BTW, Panda Security is a Spanish company https://en.wikipedia.org/wiki/Panda_Security which was acquired in March-June 2020 by the U.S. company WatchGuard https://en.wikipedia.org/wiki/WatchGuard BTW, Kerio Personal Firewall v2.1.5 (30Apr2003) does not have a Server version either, but is still my favorite firewall under WinXP.

Hi To make all new versions of Roytam browsers work under XP SP2, here is the simplest solution... download:CFF-Explorer.exe https://ntcore.com/files/CFF_Explorer.zip Launch CFF Explorer.exe and open the file in the Roytam browser Open concrt140.dll, click on Import Directory, and then click on kernel32.dll then click on the line 00037E0A - 00037E0A - 0256 and Change the function name from "GetLogicalProcessorInformation" to "FindNextFileA", and then Click on Save. do this for all roytam browsers and it now works for xp sp2.

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 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?

Hi @maile3241! You know my installation of XP is a very old one. So in the past there was no need to install XP freshly or to reinstall and therefore no chance for me to confirm your solution relating to automatic ActiveX download. But that's what I usually do before posting. Anyway I have updated my guide and linked your solution with reference to you. As we have seen some posts above it works and that's what matters.

Of course,. I said to @Dave-H some posts above the more the better and he agreed by replying the more the merrier.

Sorry, but this is no sentence and does not make any sense. A string of one or four words has nothing to do with detailed information.

If I wanted to use such old hardware with only 320MB of RAM, I would install a lightweight version of Linux such as Q4OS (Trinity Desktop). You can find it here: https://q4os.org/ In my opinion Windows XP can be installed on such hardware, and simple things can be done there, but it won't be fun if you want to use such a system basically. Modern software have much higher RAM consumption than older one. For surfing the WWW for example you need modern browsers and your size of RAM will let the system extremely slowing down or freezing completely. And an OS like Windows ME is unfortunately no solution either. I have such a Win ME partition too, but surfing the modern web doesn't make any fun or any sense at all.

Please be a bit more detailed! I guess you got this error code while trying to access MU web site. If so, you should follow these instructions completely and carefully: You must not skip any step.

Thanks for your info! But where did I say that last verion is REV3d? I wrote: You probably misread it or missed it. I provided a download link for version REV3d because there is no link for version REV3e. @heinoganda hadn't provided any download links generally. You had to send him a PM to get his latest release. And he doesn't provide download links anymore. So there is only a download link for version REV3d. As I already mentioned in my article I did my job carefully: But no problem, that can happen to anybody. The Romans said: "Errare humanum est."

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

Sorry, I can't see the mentioned files in your folders. I see only the file wsus3setup.cab in first screenshot but in second one none of them. And don't hide your extensions of files. They are important to have a look at.

@maile3241 I've checked the location of wsus3setup.inf once again. The file exists in two folders, one copy is in folder WINDOWS\SoftwareDistribution\SelfUpdate\Default\ and the other in WINDOWS\SoftwareDistribution\WebSetup\. Both files have been accessed by WU. Maybe you missed one location.

Maybe the file version of wsus3setup.inf is incorrect. Search for a version related to Windows 7. Maybe within a normal Window 7 system. wsus3setup.inf is located in folder SoftwareDistribution. But I've never used MU web site in Windows 7 so it is only a guess.
