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.

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.

There are a lot of clean installations using a CD including SP3 and IE8. If I had to install from scratch I would use a version which contains all updates until 2014 and therefore including IE8.

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

But does anyone still use IE6 in Windows XP seriously? IE8 is crap but IE6...No way!

Very strange! WSUS server + WUMT was the first method which worked without any problems from the first time I tried. Yes, it's the same.

Maybe in Explorer options you have hidden system files and extensions.

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.

Error code 0x8007000D means Error_invalid_data. Therefore I think using the XP version won't fix it probably. You have to find another version if it exists at all. Did you copy wsus3setup.cat too? Without it won't work. Both files wsus3setup.inf and wsus3setup.cat are included in cab file wsus3setup.cab.

@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.

For XP and Vista, you will also very likely need "VMware Tools 10.0.12". They can be found at the Internet Archive - BUT since they seem to also contain items in violation of MSFN forum rules, I feel it best to not "link" them here. Google/Bing/DuckDuckGo for "archive.org vmware player 12.5.9" then do "parent directory" browsing until you stumble upon "VMware Tools 10.0.12". Some people label them as "legacy" or "preVista". edit: have not used, I tend to stick with VirtualBox versions 5.1.22 and 7.0.26 as I have my system configured to use BOTH OF THEM at the same time. I use 5.x for everything except Win11 testing, which needs 7.x (maybe 6.x, don't recall) or higher. and on second thought, the archive.org links "should" be safe to post here at MSFN. according to Wikipedia, VMware has been *FREE* since mid-2024 (news to me, free is why I've always used VirtualBox instead).

Version 19 no longer installs correctly on a 26100.1 system. The taskbar is hung and keeps looping on a msg to hold down ESC to keep it from loading, but that doesn't stop the hang. Killed explorer and ran the v16 install and taskbar is back to normal. It seems v19 is not downward compatible anymore.

It is possible that the SP3 you used for comparison was somehow corrupted. On my hardware, SP3 was indeed "faster" than SP2. I am not a "gut feeling" type of guy. I took quantifiable and repeatable measurements that led me to using SP3 over SP2. Hard facts that were repeatable. No "gut feeling", no "placebo effect". That's not to say that you are "full of it", lol, it is POSSIBLE that SP2 is "faster" on your hardware. Just saying that was not the case back in the day when I compared the two. One POSSIBLE factor is that I *never* install a Service Pack 'on top of' an existing installation - I SLIPSTREAM IT INTO MY INSTALLATION DISK. Then FORMAT and INSTALL brand new.

I've uploaded v3.6.0 (for which my AMD Ryzen AI MAX 385 for the first time did all the hard, and particularly quick, work). Please confirm it works on WinXP.

Hi nicolaasjan, I still use XP SP2 for now, I tested the latest yt-dlp 2025.12.06 and when I try to download a video it says: "... api-ms-win-crt-convert-l1-1-0.dll was not found." hmm, it doesn't work with any command I try. (example: yt-dlp --version ) Can you please keep yt-dlp be able to work on XP SP2 if possible? I would also like to say a big THANKS to you nicolaasjan for all your hard work with yt-dlp and making video download possible on older OSs.

if it happens in beginning then there is no clue how to fix it.

I'm not a developer. If roytam1 is a professional, he should look for the causes of the bug and the browser version himself, not send users who do not understand many technical issues to do it. It would be very funny if when reporting a bug in firefox, mozilla would say "you look for the problem yourself, we don't know anything".

You wouldn't have that "problem" if you didn't spend 'all your time' to go through *ALL* posts by your 'favorite people' and post "likes" to content in JANUARY OF 2022 for NO REASON other than it was one of your "favorite people". "Kids these days..." edit: when you're done with all the "likes" for your 'favorite people', I'd kind of suggest you (and the other's that "do this") at least kind of EVEN THE SCORE by doing the SAME for folks like roytam, feodor, tihiy, et cetera.

Hi, I just make a nice hack. I get a lot of Arduino nano for 67 Cent from China. They work under Win10 but not under XP SP3, "Unknown USB device". I use the Arduino IDE ver. 1.8.9 portable, means no installation. It has the exotic USB serial VID_0843&PID_5740. So, I take the win7 driver STM32_vcp_driver.zip from STMicroelectronics which has funny VID_0483&PID_5740. There I edit just the stmcdc.inf file only at this part ;------------------------------------------------------------------------------ ; VID/PID Settings ;------------------------------------------------------------------------------ [DeviceList.NT] %DESCRIPTION%=DriverInstall,USB\VID_0843&PID_5740 [DeviceList.NTamd64] %DESCRIPTION%=DriverInstall,USB\VID_0843&PID_5740 Right click on this modded stmcdc.inf "install", and voila, this Arduino nano clone from China works perfect under XP SP3 Dietmar

No matter how many times I tried, I couldn't achieve a good result with it, @NotHereToPlayGames recommended WinReducer, but I don';t know whether it works with 7, sorry. And NTlite is simply awful, in my humble opinion.

XP will work with DESKTOP Haswell CPU/GPU. but not Haswell Refresh *like G3470 or the such.

No. https://msfn.org/board/topic/182660-intel-hd-haswell-drivers-modded-for-vista/#findComment-1198948

Thanks for replying! And yes, I know very well your opinion about POSReady updates for Windows XP. But on my computer, Thorium only works in my Windows XP system with all POSReady updates. Maybe by accident, and there is another causer for my described issue. That's all a bit strange. Are there any specific requirements for Thorium in terms of system software, especially regarding runtime libraries and so on?

Now, a question to all who are running Thorium under Windows XP Professional SP3 with all updates after SP3 but without any POSReady updates. Does Thorium work under these conditions? I have two Windows XP installations, one with and one without POSReady updates. When I start Thorium on Windows XP without POSReady updates, it crashes randomly without any messages. With crashing I mean a sudden closing of the browser without any actions by me, either directly when starting the browser or seconds respectively minutes later.

ROG - precisely about Asus PS/2 Keyboard/Mouse combo port. "I have purchased 6 PS/2 Y splitter..." https://rog-forum.asus.com/t5/z170/ps-2-keyboard-mouse-combo-port/td-p/574618

Either of you tried to mod the desktop drivers? There's a chance up to R430 Kepler might work. https://www.nvidia.com/download/driverResults.aspx/151873/en-us/

Yes, but not via DVI. "Nov 3, 2013 — Dual link DVI cannot support 10-bit color at 1440p. 1920x1200 or 1920x1080, maybe." https://linustechtips.com/topic/71182-does-dual-link-dvi-support-10-bit-colours-1440p/ Like I said, try Display Port.

First, try to forcefully set the full RGB mode. Second, 10-bit is only supported for their pro-grade cards, no wonder you see the black screen, even if the monitor supports it. Third, newer cards are tend to be overbright, so again no wonder there's a drastic distortion, they simply distort the vibrancy. Try lowering the digital vibrancy setting.

@Cocodile, thank you for the information! I had a chance to read the topic soon enough after you posted! A very interesting fact they mentioned, even VPN services are infested with that malicious AppMetrica Yandex API, hundreds of them. We'd have to assume the popular Browsec also has it. No wonder it has so many negative reviews and articles questioning its security and reliability. Such VPN services are definitely not advisable to use on iOS.

I'm afraid not, because it would require backporting the whole shared memory API from Windows 10 build 1809 to windows 8.1. Better/easier/legally safer to build chromium from scratch (source), which is open, so anyone can try.

My version of 11/12/2019 is probably the same that you have used from November 2019. Then it works offline with this version but using WSUS server + WUMT doesn't work in your system. Is that correct?

Thanks for upload of your Windows Update log! As far as I can see in you have used WSUS proxy method to get notification from systray shield. Is that correct? As mentioned above it works in my system too but that's not the problem actually. Only using HTTPSProxy switched on, no WSUS server. Is it then working too? I don't think so.

Thanks for information! I already knew that. Using WSUS method Automatic Updates applet works flawlessly. As expected the notification shield appears in systray and reports one urgent update is missing.

I use Glarysoft's Quick Startup. It has a delayed startup feature too. Very good tool and afaik more recent. No, I meant wuauclt /detectnow doesn't work for me too. No notifying of new updates (and in my case there is one), no shield in systray, no entries in event log. Sorry for confusing! It's not my day! Automatic Updates Control Panel applet is not greyed out and can be called up but changing settings by this applet has no effect.

@maile3241 Where is it missing? In my third step I already wrote to add it to Trusted zone of IE. Maybe a little bit more explanation, please!

@ExtremeGrief Sorry, I should do nothing. I am not the author of these packages and patches. I am a user like you and have examined my problems by restoring MU. This little guide some posts above is the result of my examinations to help other users. And once again I "should" do nothing. But you should reflect on how to speak to a member. First read the whole thread and then you will understand.

@Dave-H Maybe perform all steps in my new post: As I told you I had a lot of troubles to restore MU in my system. I had all error codes someone could get. I think your error code has been one of them. Maybe you have a BIOS date/time problem due to low cmos battery but I don't think so. My advice: Do all the steps once again and do not miss anyone! You know Windows is very often a mystery.

I was wondering it myself , First - there is a "service worker" tracker folder [which is not deleted], second - there is a folder named "dailybackup" ?!?!. It has many files with "favdb" extension and each login session data for every day, possibly they are responsible? Yes , would be nice to hear @Humming Owl's opinion . Thanks.

Sorry , I didn't observe such phenomenon on Visat . Everything renders very fast on my PC. Vista is very fast. Perhaps you meant this happens with Windows 7 Aero ?

There you have it ! You need ONLY 64 bit . I will share this direct link to ALL official Opera versions from their archive . https://get.geo.opera.com/pub/opera/desktop/ You just need to extract it with 7zip , replace the files in your portable version, no installation needed . And use that portable launcher. Everyone , notice he has Aero working with Opera...

I didn't have any problems with "SP0" , except that it somehow limited some games in terms of video memory . I mean it did have that weird limit with newer games that needed more than 512mb of VRAM . I'm talking about both 32 and 64 bit . That was fixed in SP1 . As for the speed , I had superfetch and indexing disabled and everything was smooth (with SP or without), very similar to XP , I agree that XP (out of the box) could be faster in theory , I think it's because it had less unneeded services , but they can be disabled in Vista. The thing that really bothered me - freaking white folder background (which coudn't be changed by a simple user). What about you ? Edit : I too replaced Vista on my laptop for some time because I couldn't change the background . But I went for Win2000 Pro.

Well , it is already enough to run Opera . Maybe if you have some spare time and don't mind adding just shell32 sooner , with this function added, I'll start testing Opera with my starter. It's no hurry , of course , I have plenty of others to test . Today I've tested latest Slimjet - working , of course with this flag.

What's there to check out ? You've already done a marvellous thing ! One can make this flag permanent and use the browser with it forever . I think it's better to investigate what causes the locale problem with the extensions . Or , as I said earlier , figure out how to force everything to use English (block other locales) . I already added this flag to the starter (with ungoogled) quite some time ago. Oh , and extensions without locales will work (I checked with chromium 86). By the way , the new files are already in the mega folder ?
