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.

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.

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)

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.

StartAllBack 3.9.19

I did it for testing (manually applying 3dyd's changes to the source of official PyInstaller 6.17.0) and converting into a wheel (built with 32bit toolchain from here on Windows 10). pyinstaller-6.17.0-py3-none-any.whl (for XP) pyinst-6.17.0_yt-dlp_x86_XP.7z

no clue, check for upstream if problem persists. (but remember, youtube pushes AV1 content which is too heavy for old machines.)

fileextd.dll its a old rare file that provide some functions that xp useally dont have - it can be seen as kernel extender i dont know its origin either some say its from the xbox and a official file while other say its a handmade file by someone maybe we get some more information about it what i know is that it is shown as used library on microsofts website: https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-getfileinformationbyhandleex then "Kernel32.lib; FileExtd.lib on Windows Server 2003 and Windows XP"

Did you set up the proxy properly following the instructions? How did you start the proxy? Which version of Windows XP is installed in your computer? What is the state of updates? No detailed information, no help is possible! And I wrote a lot before, but no statements from you what I suggested: OnePiece Windows XP Post-SP3 UpdatePack, Linux Q4OS (Trinity Desktop) and so on. Truth be told, not much fun helping you!

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."

@roytam1 I believe that he is asking not about xpi min-ver issues, but rather his issues with video playback in Serpent.

It's wuaueng.dll regression for calculating updates metadata chain, specifically these functions CUpdatesToPruneList::PopulateSupersedenceInfo CUpdatesToPruneList::AddSupersedenceInfoIfNeeded they fixed it for Win 7-8.1, but they never backported the fix for Vista/Server 2008

... Well, this isn't a very reassuring answer, you do realise that ... Don't know ; perhaps @user57 is on the right track on this (or even @cmalex, safe may he be, knows more ); the question to be asked is why did it magically appear in the latest yt-dlp WinXP compiles, whereas it wasn't present (needed?) all that time before? ... Can't tell; my AV solution gave it a "clean bill of health" ; you can try to see if the WinXP packages launch and function OK WITHOUT it, then take the necessary steps to remove it altogether; I'm not being paranoid (I think ), but I'd rather not have it there, if it isn't indispensable... Best festive wishes ...

Yeah I remember years ago, I used to be very against using old OSs such as XP because of security update issues. Then I relaxed on it, but over the time morphing my stance to just include Vista and up. Now, with my fully ditching any trace of Vista or older, I stick to JUST keeping Windows 8 going. I don't care about the security updates so much. It's just that I like how Windows 8 looks and feels vs Windows 10. However, I've really started to see Windows XP as archaic. It's odd for me to think that in 2025, Windows XP has ANY place on a running PC, but this time around, I'm not really worried about how others feel about my expressing that opinion. It just is what it is. When I made a comment in one of Roytam1's threads about using Betterbird vs MailNews or Interlink, I was reminded that the goal was to have a client running on XP or higher. My first thought was, "Oh yeah - that!" It feels more like an irritation that won't go away, rather than a goal to aspire to.

I cannot reply in your Russian forum but you are mistaken regarding IFSMGR.VXD 2227, it was Q301540.EXE and not 302540. How can you ignore it!

One can get tired of exporting one by one very quickly. Let's see, There we have often cases where pics and videos are stored at another website, so even if you export the main (root) website cert, the pics will show empty, the browser will prevent the off-site untrusted (un-certified) connections. Last but not least, many modern AV scanners use your cert store to check the sites and/or your browser's executable. As we see, Tripredacus uses official browsers, perhaps he uses such AV software, too.

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.

Yes, it's the tool I used about a decade ago, thanks for the right link, I can confirm it works the easiest way, even for beginners.

I'd say, it comes as no surprise after a quarter of century. What about Fujitsu-Siemens, Fujitsu, or just Siemens? You don't consider them? It'd be a perfect choice, as of they have lots of thin clients.

I can't really say whether the problem also occurs in Pale Moon (32-bit or 64-bit ), as I don't use this browser. It was also just a guess. In any case, the Speed Dial 0.9.6.18 and Tab Utilities 2.1.2 extensions in the latest New Moon 28 32-bit release definitely break the session restore function on my Windows XP system. The Session Manager extension only generates some errors in the Browser Console but is still working so far. @UCyborg For reproducing this issue, it is simply enough to only use either Speed Dial or Tab Utilities. So, for example, disable Tab Utilities and Session Manager, start latest New Moon 28 (32-bit), close some tabs and restart the browser. Then you should actually notice that the already closed tabs are still there which means the internal session (re)store does not work anymore if Speed Dial is enabled. You should also see the error message "ReferenceError: nsIWebNavigation is not defined" in the Browser Console when closing tabs from the current browser session. The more tabs you close, the more error messages you will get. At least, that's what I observe in dirty or clean New Moon 28 (most recent version) profiles on my Windows XP 32-bit computer. And I'm pretty sure that I'm not the only one affected by this issue. Maybe, other members may also confirm this issue.

Regarding Speed Dial I found a ReferenceError in the Browser Console: ReferenceError: nsIWebNavigation is not defined[Learn More] speeddialOverlay.js%20line%201595%20%3E%20eval:42:13 This error message is generated every time I close a tab. And here is a screenshot taken from NM's Browser Console: And I got this message after resetting Speed Dial and browser restart: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: chrome://speeddial/content/speeddialOverlay.js :: startBackgroundLoad :: line 1770" data: no] (unknown) So, the culprit seems to be the JavaScript file speeddialOverlay.js. The main problem with Speed Dial is that when tabs are closed, they are there again after a restart. The current browser session is therefore not restored as it has always been. Same applies to the extension Tab Utilities 2.1.2.

What is this? The main script inside the legacy extension turbolauncher.xpi.

Please, don't come up with your "gut feelings"! I have presented all the essential facts that you have not commented on. My presentation has nothing to do with subjectivity and hypotheses. But as I said, it's offtopic here anyway and actually totally irrelevant. Your cucumber is old and mine is many years older.

Ok. As far as I can see, my Intel Pentium 4 Northwood 2.8GHz 32-bit has a higher operating frequency than your Intel Atom 1.6GHz. In all other categories, your CPU is better than mine. L1/L2 cache, thermal values, instruction sets and so on. And you use DDR2-RAM which is much faster than the old, slow SD-RAM I use. Furthermore, I assume your Intel Atom CPU supports Hyper-Threading technology, my CPU does not. Even your Intel GMA 950 graphics is more efficient than my NVIDIA GeForce 6200 AGP 4x (8x is not supported on my motherboard). And as we all know, the operation frequenzy is difficult to compare regarding completely different processors, i.e., a higher frequenzy value does not necessarily mean a higher performance. BTW, which Intel Atom CPU is it? N270? All in all, I think your old Acer is faster than my old computer.

That's a general problem here on MSFN. If members/users have problems, they are very communicative and willing to provide information. But when it comes to selflessly contributing something to the cause, a certain listlessness prevails. Very regrettable. In principle, the same people always make a contribution here to move the cause forward.

Good comparison! This clearly shows the positive effect of rebasing I stated in previous posts. 66.6% less RAM consumption. That's a lot. BTW, maybe your CPU is weaker (I can't remember what kind of CPU you have) but your system is equipped with 4 GB RAM, mine with only 1.5 GB RAM (slow SD-RAM, i.e., no DDR-RAM).

Edge is based on Chromium and closely follows the upstream changes, so no wonder.

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

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.

I don't know what's your problem. Forget about IE 7 and install IE 8! If installation of IE 8 doesn't work, then your system is faulty and a fresh new installation is necessary. Internet Explorer is crap generally but if we need it then, please the latest version. And there is basically no problem with IE 8 in Windows XP.

@Dave-H I am analyzing the automatic updates applet problem we both have. For me it doesn't matter actually I don't use automatic updates but you know I hate errors in my system. Using HTTPSProxy switched on and setting automatic updates to "Notify but don't automatically download or install them" could you trigger automatic updates by executing command wuauclt /resetauthorization /detectnow under two different conditions? First condition is to execute command proxycfg -u and second condition is to execute command proxycfg -d. Then I would like to ask you to upload a copy of your Windows Update log. PS: And don't be afraid! None of these commands will harm your system.

@Dave-H Requested certs have been sent via PM. And give your ProxHTTPSProxy a second chance by installing original certificate in program folder. For this purpose apply ProxHTTPS Cert Install.exe. Maybe your generated HTTPSProxy CA certificate is problematic when you try to connect to MU. You know my HTTPSProxy CA certificate has a different timestamp. And don't forget to close HTTPSProxy by clicking exit in systray menu if using ProxHTTPSProxy.

@Dave-H A little correction. I meant registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate and there the value of LastRestorePointSetTime. Here is my value: 2019-04-12 13:45:09. You see it's your English format. Try the point in time you have there first! Then you may try other points in time. The method "Turning back time" can mean to go back one year or one day. You just have to try out. It's trial and error. Maybe it works. I'll forgive you due to your "senior moment". But where is the 'Use HTTP 1.0' option? I have only these entries: Use HTTP 1.1 and the Use HTTP 1.1 through proxy connections. If there wasn't both entries it had to be assumed that your Internet Explorer was not properly installed or is faulty. Anyway, look at last post of me above to download screenshots of my services in better quality.

@Dave-H Due to the fact that the Microsoft service HTTP-SSL was disabled in your system I think it is a good idea to compare our Microsoft services and their status generally to be sure all necessary system services are still working. There might be some services not being essential but anyway in my system Microsoft Update is working properly. To do that download the tool ServiWin 1.71 from NirSoft. Here is the homepage link: https://www.nirsoft.net/utils/serviwin.html and here the download link: https://www.nirsoft.net/utils/serviwin.zip. It's portable so there is nothing to install. I've taken two screeshots of all Microsoft services existing in my system listed by ServiWin. Columns with German description have been faded out. So it's much easier for comparing. Here they are: https://imgur.com/az67Jo6 and https://imgur.com/bIQ2jIN.

No, in step 3 there are three urls related to MU. Maybe you have missed it.

I have reinstalled these four updates flawlessly. I get a fully loaded Microsoft Update site using HTTPSProxy (that's very good ) but when searching updates I get error code 0x80072F78 again. I tried to load it a several times. See my screenshot https://imgur.com/xOfqchc

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.

I think those are the consequences of the tab freezing nonsense google introduced in 7.xx chrome versions. https://www.tenforums.com/tutorials/146276-how-enable-disable-tab-freezing-google-chrome.html

1 - I shan't discuss anything about "performance" of any KGB related software since I've clearly made my point, besides we don't know who's behind those "labs". 2 - Please discuss "antivirus" programmes and make their comparison in the appropriate topic. (not here, obviously) 2 - Newest programmes that work with Vista's ex-kernel by @win32 . Just to name a few : Chromium , Opera , Centbrowser , Chrome , Firefox and it's forks , Chromium Ungoogled , I've also read about TOR ( though I haven't tried it myself, but it should work too, since it's based on Firefox) , newest FFMPEG , 4K Stogram , Grids (quite popular desktop versions of instagram) , Aiseesoft Screen Recorder , Minecraft , Scrap Mechanic , Cemu , plenty of modern games that use Mono engine, quite a few of modern DX11 titles that use Unity. Again , I really don't understand what you were trying to say . It sounds like you're not satisfied with this jaw-breaking progress regarding the ex-kernel. And why did you even mention Win7 ? This topic is about Vista , for true Vista lovers. And no, our ship "is not sinking" . Are you trying to devalue win32's work ? It's just fabulous ! He's just fabulous ! We all should be grateful ! Perhaps you (yourself) can help him with the work ?

Thank you for the info ! Pehaps you know where one can compare the hashes ? The original and this one.

That's exactly what I did , and what I got in return , except for rudeness and total lack of respect , not to mention him going off-topic ? I'm definitely getting a very cold welcome here , now from this supervisor too . Yet I didn't do anything against the rules and was polite in every topic . Is it something personal ? Why did you just backed him up ? You took his side for what ? Not even a word or a warning for being rude and staiyng off-topic ? Well, that's a good example for other members. I simply won't take any blame for asking him to translate his local language into English . Are any other supervisors reading this ? I mean @dencorso
