My Problems:

At some point in the last few months, a change was made that caused Widevine to lose its ability to play DRM media in XP.

Prior to this change I had at least six different chromium-based browsers that were playing DRM media just fine in XP via the Widevine plugin.

All of those browsers are now unable to play DRM media via Widevine.

You can test your browser here: https://bitmovin.com/demos/drm or here: https://demo.castlabs.com/

I think the change that was made might be the one which was mentioned here on  2018-09-05:

"Widevine CDM for Chrome 58 (or earlier) are no longer supported."

Hi!

I just built a Windows XP PC for early 2000s gaming, and have run into a weird issue that I can't seem to pin down or get rid off. The easiest way to show it is through the videos I've added below. As you can see, the rendering of pretty much anything is not smooth, but instead there is a tiny consistent pause every second or so, which is consistent regardless of the workload. In games, apart from a choppy frame rate,  it also affects the sound (and the DirectMusic test, which is also somewhat choppy), though .mp3s and the like play fine in Windows Media Player. Having tried to narrow down the issue, I've done the following:

- Switched out the CPU

- Switched out the graphics card (ran a Raden 9600XT at first, switched to a Geforce 7600GT)

- Removed the sound card

- Increased the RAM (from 2Gb to 3Gb)

- Switched out the harddrive

- Reinstalled Windows XP (also tried Win2000 and had the same issue)

When reinstalling the OS, I've run the DirectDraw test first thing after installation (i.e. no driver installs), and the problem persists. At this point, I have no idea what else to do, and so any help troubleshooting this would be greatly appreciated.

Thanks!
Chris

Specs (current):

- Shuttle AN35N Ultra (nForce2 Ultra 400)

- AMD Athlon XP 2600+

Here's the issue in the DirectDraw test (no drivers, fresh install)

TL;DR, there's now an easy way to enable MP4 (H.264 + AAC) HTML5 video support in Firefox on Windows XP using the Primetime Content Decryption Module plugin by Adobe (distributed by Mozilla). Meaning, you could get rid of Flash (with some caveats). The irony of course being that you'd have to use another thing by Adobe , but at least it's something not as prone to security problems.

NOTE: If you're suddenly unable to watch videos on Facebook (or any other site) even though you haven't changed anything re: Primetime, you may have to start spoofing your browser UA (user agent) string to work around this problem. See the posts starting here for the specifics. (EDIT October 30, 2017)

IMPORTANT: The Primetime CDM plugin can no longer be downloaded from Adobe servers, which means that attempts to automatically download the plugin through Firefox GUI will fail even if you edit the download configuration URL per the old instructions below. From now on, you will have to manually install the plugin for all new Firefox installations and any new profiles you create; see the new instructions below. If you already have the plugin installed, you don't need to do anything. (EDIT July 18, 2017)

If you're here because MP4 video has stopped working after you upgraded to Firefox 52.0, see this post. If you still have problems, make sure you have all of the required preferences listed below and their values are set correctly.

The Adobe CDM doesn't work for EME on WinXP, and we were trying to get it working for unencrypted decoding of MP4/H.264/AAC files on WinXP, but it has a bug that causes it to crash on some systems. So we turned unencrypted decoding via the Adobe GMP off. Adobe have decided that they aren't going to support WinXP furthermore, so they're not going to be fixing that bug. We don't want to use unsupported decoder for unencrypted decoding.

Technically, this plugin has been added to FF for DRMed HTML5 video, but it can be used to play non-DRM as well. It's not officially supported on XP, but hey, neither is XP itself, right? I've been trying it out with FF 46 (later also confirmed with 45, 52 ESR and 47-52) on XP Pro SP3 x86 (with POSReady updates, though I doubt that matters any) for about a week now, and the experience has been pretty encouraging. The vast majority of HTML5 videos have worked without a hitch; ~5% have had 1-2 temporary freezes (the video stops, the audio continues with some crackle), which can be easily worked around by moving the video position slider back a bit and then forward again to where the freeze happened. I've seen only one (1) case of a show-stopper error message about "corruption or unsupported features in video" (quote not verbatim) that couldn't be worked around by jiggling the slider (not a crash, just an error message and the video stopped). You may not necessarily be as lucky, though, as the reason the plugin is not included by default by Mozilla is its reported crashing on some high profile sites.

(If you're interested in getting this to work on Windows 2000, be sure to read @blackwingcat's post below in addition to this one, and why not his blog posts (1, 2, 3) as well (in Japanese, but with screen shot images).)

To be able to install and operate the Primetime CDM, add and/or set the following FF preferences in about:config (be careful, all of these are cAsE sEnSiTiVe!):

media.gmp-eme-adobe.enabled (boolean; true)

media.gmp-eme-adobe.forceSupported (boolean; true; FF 49.0+)

media.gmp-eme-adobe.forcevisible (boolean; true; FF 45-48, no longer used in 49.0+)

media.gmp-eme-adobe.visible (boolean; true; FF 49.0+)

media.gmp-eme-adobe.version (string, not integer; 17; required for manual install now that automatic install is no longer an option)

media.gmp-eme-adobe.abi (string; x86-msvc-x86 (EDIT: x86-msvc-x64 for 64-bit XP users); not required, you can set it if you want to more closely mimic automatic install)

media.gmp-eme-adobe.lastUpdate (integer; 1500000000; not required, you can set it if you want to more closely mimic automatic install)

media.gmp.decoder.enabled (boolean; true)

media.eme.enabled (boolean; true; defaults to false if you downloaded a DRM-free version of FF; thanks @heinoganda for pointing this out)

media.gmp-provider.enabled (boolean; true) may also be needed, if not already present, as found out by @VistaLover, in the case of SeaMonkey 2.49.5...

To manually install the actual Primetime plugin software, first download the ZIP package (backup link) from @sdfox7's site (he has plenty of other useful XP stuff there as well, definitely worth checking out!). You can use the following checksums to verify package integrity:

To install the plugin:

1. Open your FF profile folder. An easy way to navigate to it is by opening about:support in FF and clicking the Open Folder button next to Profile Folder.
2. Inside the profile folder, create subfolder gmp-eme-adobe and open it.
3. Inside gmp-eme-adobe, create subfolder 17 and open it.
4. Unpack the Primetime ZIP archive into folder 17.
5. Folder [your FF profile path]\gmp-eme-adobe\17 should now contain three files: eme-adobe.dll, eme-adobe.info, eme-adobe.voucher.

After this, check the Plugins in your Add-ons list and you should see the Primetime plugin listed and ready for use. If you don't see the plugin there, make sure you've set all of the required preferences as described above and put the files into the correct subfolder. Restarting Firefox to complete the manual install isn't usually required, but try it if the plugin doesn't appear, (Also, remember that if you have more than one Firefox profile, you'll need to repeat these steps for each of them individually.)

Set the Primetime plugin to Always Activate, Flash to Never Activate (not strictly necessary, but better for testing), and go to Youtube HTML5 video player check page. Both H.264 and MSE & H.264 should have blue checkmarks. You may want to try this test page (kindly suggested by @dencorso) or some Twitter videos to quickly make sure H.264 really is working (with Youtube you can get fooled by WebM getting played instead).

In theory, you could uninstall Flash at this point, but realistically it's probably wiser for now to leave it installed and disabled in the browser. Personally, I installed the FlashDisable extension to quickly toggle Flash on some of the sites I frequent that don't support HTML5 video. Some of those insistently serve Flash video to desktop FF without even checking if it can do HTML5 video or not. That can be worked around by faking a different user agent string, but for now I've found it more convenient to just temporarily toggle Flash back on for them. FlashDisable supports the Ask to Activate setting, so you don't have to worry about other sites if you forget to turn Flash off again.

Based on what Mozilla devs have been saying on Bugzilla (Unhide Adobe GMP on Windows XP, Hide Adobe GMP on Windows XP in Firefox 46 and 47, Make Adobe GMP available to Windows XP users in Firefox 45 and later) it seems quite possible that this plugin could soon (FF 48+) be made available without having to use any tricks (or pre-release versions), but I suppose it's also possible that the current situation will continue indefinitely (or even that the plugin will eventually be made more difficult to access under XP). (EDIT July 18, 2017) As you've likely heard, FF 52 ESR is the last version of the browser that's going to work on XP (unless some intrepid person forks a special version for us). In a way, this is a blessing in disguise, as Primetime support has been completely excised from FF 53 and Google's Widevine CDM doesn't have our helpful side-effect (and doesn't work on XP), but ESR 52 will be supported well into 2018. So, why not make use of it while we can, right?

Note that HLS streaming is not natively supported with this plugin. It does work on sites coded to use some JS library or player to work with HLS, but not for directly playing .m3u8 video sources. You may want to keep an eye on developments with hls.js in general and firefox-hls in particular if a favorite site of yours falls into the latter category.

What happened? FF blocs Flash...

Solution:

Flash 18.0.0.209 active-x and plugin  (direct downloads)     

Enjoy!

Does anyone know how to correct this

An error occurred in the secure channel support

I get this in uTorrent 1.8.2 and othe utorrent clients, as much as i can find utorrent support HTTPS or its to do with TLS 1.2

is there a fix for this

all other torrents are ok apart from this site

Welcome to the club "Windows XP Spotter", a club which aims to collect pictures of running Windows XP (or XP based, like WES, WePOS, POSReady2009 and Server 2003) machines during these days. I'm gonna start:

London Victoria Station, Ground Floor, McDonald's uses Windows PosReady (XP-based) tills, but I didn't manage to get a pic of them (yet).

In the meantime, I got a supermarket (running XP):

And a friend of mine living in Italy, Ivo, sent me this:

Ok people, go out and conquer the world shoot pictures of running XP (or XP-based) machines.

I have XP SP3 updated under the guise of "faux POS" (not all updates applied though)

Lately I find some cases - more and more often - of HTTPS sites that :

- under XP, won't open in Chrome (nor IE), i.e. using Windows own crypto API - but that -

- will open under Firefox - which has its own crypto stuff - even a very old version (3.5) works !

- under Seven, for compare, same sites do open even in Chrome (or, God forbid! IE).

An example page there exhibiting the phenomenon : https://www.aidanwoods.com/blog/faulty-login-pages/

Is it expected with fully updated XP SP3 and/or "POS" windows ? Or have I missed a related update ? For reference I have : crypt32.dll version : 5.131.2600.6459 (xpsp_sp3_qfe.131005-0434) and rsaenh.dll : 5.1.2600.6924 (not that I'm half sure those particular dll's are the keys of the problem)... 

Hi folks!

Python (multi-platform programming language) officially dropped its support for Windows XP. Python programs are slightly different compared to other programs, because they are not compiled when you download them: they are just scripts. When you click on them, they will look for Python "assemblies" in order to quickly compile the program during the runtime. (It's not 100% true, but that's an over-simplyfied explanation). So... since Python dropped its support for XP, this meant a big issue for Python programs 'cause the old "assemblies" can't compile 3.5 scripts; that's why Python 3.5 Runtime Redistributable - Windows XP is here for you.

Please note that this is an unofficial Runtime Redistributable package. Extract it to "C" and rename it "Python35". The core and its dependencies have been compiled to run in Windows XP, but I have been able to test with a single program 'cause I don't have any other programs written for Python 3.5.

You'll find the official Python website screen and the backported version below.

Since there's not much info out there on the web unless you spend a considerable amount of time googling, I thought i'd post the solution so more people can find it quickly.

Update: The latest problem with activation affects both XP and Vista however it’s relatively easy to fix, you need to update your root Certificates (The same issue causes problems browsing the net too)

I have created a Batch script that will download and update the Root Certificates accordingly but it will be a couple of days before I can post it.

Below is the Original Fix I posted

Turns out it's exceedingly easy to restore Windows XP Online Activation

• Open the Start Menu
• Right Click on Internet and choose "Internet Properties"
• Goto the Advanced Tab
• Scroll down near the bottom to the Security Section and uncheck both:
• "Check for publisher's certificate revocation"
• "Check for server certificate revocation"

Now you can activate online as normal or use the "Windows XP Product Key Change Tool"

I would reccomend re-enabling both options afterwards even if you dont use Internet Exploder (which you REALLY REALLY should not be)
 

If you’re still having problems:

I highly recommend downloading the “Windows XP Product Key Change Tool” it’s an official Microsoft tool and you should be able to download it from majorgeeks worked in every other instance for me where the built in one didn’t. (And in think it also lets you use different type of keys from the media the OS was installed from, such as Retail on OEM and such)

Also make sure your clock is set correctly (A common source of TLS problems)

Please

I am unfamiliar with add on creation and I'm sure someone inclined in this can do it on 'no time' or that someone may be interested in such a pack.

Scope of objective

(Assume target system is an offline one; has automatic updates components disabled/removed).
At present, people should have to do the following to a clean XP Pro SP2 Source:
-Add official SP3
-Add XPSP3_QFE_UpdatePack (Post SP3 addon, available at RyanVM.com)
-Add XPSP3 QFE_POSReady (Official updates additional to/since the above pack, until 17/09/2018, the last time QFE_POSReady was maintained)
AFAIK this is the correct integration order (using nlite).

Lastly, for IE8 functionality:
-Add community-made IE8 add on

The most recent community IE8 add on is this one - last edited 2014.
However microsoft has released IE8-related (POS2009) updates since then.

ie8-mui-x86-enu.exe < may be included in 2014 pack
ie8-windowsxp-kb2598845-x86-enu.exe < is included in 2014 pack
ie8-windowsxp-kb2888505-x86-enu.exe < is included in 2014 pack
ie8-windowsxp-kb4493435-x86-embedded-enu.exe < cumulative update released 2019, not included
ie8-windowsxp-x86-enu.exe < browser installer

This 2014 addon needs to be updated to include new updates - kb4493435 is not in XPSP3 QFE_POSReady.
Can anyone make a new update pack comprising this latest cumulative update?

Background
A non-IE8 related kb4019276 is included in XPSP3 QFE POSReady - it enables TLS system wide; manual import of registry keys is necessary to enable it fully (details on RyanVM). Ability for visual tick boxes was added in cumulative IE8 update kb4316682 (30/5/2018), later superseded by kb4493435 (5/4/2019), that shown above. All IE8 addon packs to date lack this update.

Even though I'm not interested in IE8 (I use superior k-meleon which has its own TLS ecryption tunnel integral) the tick boxes in Internet Options (in XP control panel) enables explicit control of TLS system-wide, which some XP programs do require control of. Registry key import is more hassle.
Test: using nlite, successively Integrate IE8 + subsequently remove IE8. The only way to enable visual tick boxes is to install XPSP3_QFE_UpdatePack + XPSP3 QFE_POSReady + (updated) IE8 addon.

************* EDIT / UPDATE:

On a test install I managed to get the boxes to show even w/o IE8 installed.

To achieve this, here are Hotfixes that were manually added (with nlite):

ie8-mui-x86-enu.exe
ie8-windowsxp-kb2598845-x86-enu.exe
ie8-windowsxp-kb2888505-x86-enu.exe
ie8-windowsxp-kb4493435-x86-embedded-enu.exe

*************

Off topic: An observation re: XPSP3 QFE POSReady (last updated 17/09/2018). Its missing minor updates, for example:
SSE related kb4473077 (7/12/2018) which superseded kb4463361 (5/10/2018).
Windows Installer related KB4486464 (3/2/2019) eclipsed kb4340937 (10/8/2018).
New kb4500331 (7/12/2018) isn't included either.

I've already asked the creator of QFE updates about this minor quarrel (redident of RyanVM).

Note: throughout this post date fromat is DD/MM/YYYY, contrary to MS Update catalogue MM/DD/YYYY.

Its my first time here, so very nice to meet you 

My System has Windows XP (Proffesional 5.1) installed, My hard drive is: WDC WD1002FAEX-00Z3A0 (1TB)

I want to add another hard drive to this pc

My question is:

Will this hard drive will work with windows XP? Western Digital Purple 2TB 64MB Sata III WD20PURZ

I read in here that someone said that: 

Quote

the 64 meggers should be 4k if memory serves right, thus youll have to align it prior to use with anything older than vista/w7.

But still, I would like to know if he is right or wrong...What kind of hard drives I must avoid as an XP user?

Hello guys. I have an HP compaq nc4010 with some issues with it's infared transceiver. The first issue is that the Infared "Wireless Link" applet in the control panel refuses to open, simply doing nothing upon being clicked.  The Second issue is that when attempting to transfer files to or from this HP, the other computer gets the Infared prompt, but this one does not. Attempting anyway on the other computer always ends in "the other machine actively refused it." The infared service is running, and proper drivers appear to be installed.

Thanks for any help.

Firefox 54 is the first multithreaded version

You can force "multiprocess mode" in FF 52 by creating the Boolean preference browser.tabs.remote.force-enable and setting it to true. (Also works in Serpent, BTW.)

This splits FF (or Serpent) into two processes. Not as good as Chrome, where each tab is a separate process, but it can still help.

Hello . In the past I heard of some tries for creating WinXP drivers for the GTX 10xx (GTX 1060 etc) video cards , so I'd like to ask if there has been any development yet .
