This thread is'nt a place for discussion about these betas, I'm making this thread soley to help those who are having a problem with WMP 10 after installing a newer build of SP2. If you installed WMP 10 and then uninstalled SP2 to install a newer build of SP2 and WMP 10 now looks like WMP 9, this thread is for you.

Warning: I don't guarantee this will work but logically it should and it has worked for both bangbang023 and myself. I have no idea if this will work on longhorn, Server 2003, Windows XP 64 bit edition, or anything else besides Windows XP 32 bit.

To keep it short and simple, I'm not going to go through all the history of what builds I was using and why, because I honestly think this behavior will be the same across all builds. If it's not, by all means, please inform me. Before you begin, note that you should not open WMP at all until you're told. Doing so could cause problems and you might have to start over. Also note that I haven't thoroughly tested this, but as I said, it has worked for me and bangbang023.

Here's the instructions to get WMP back to version 10 beta:

1. Extract the contents of the WMP10 installer to a folder, say "C:\WMP10" for ease of use.

2. In this folder, select all the INF files except WMP10.INF. Right click all these files and choose "Install". This process will take a few minutes because you're installing several INFs at once.

3. When step 2 is finished, right click WMP10.INF and choose Install.

4. If you get a message asking you to reboot, do so.

5. Finally, navigate to "HKEY_LOCAL_MACHINE\Microsoft\Software\MediaPlayer\Setup\Installed Versions". There should be three binary values:

wmp.dll

wmplayer.exe

wmploc.dll

Set ALL of these values to the value "00 00 0A 00 91 0D 00 00".

6. Open WMP and you should be using WMP10 beta (Y)

For those of you who are lazy, I have attached a registry file that you may import in place of step 5.

WMP_10_fix.reg

Does running c:\windows\inf\unregmp2.exe /UpdateWMP not work?

I don't know, I didn't know about that file until you mentioned it. Plus I'm more into manual fixes anyway :p If someone gets this to work before they use my solution, please say so (Y)

He did that 2 hours ago, Ok, I see your point. But my instructions are different from his. He says copy all the dll files to \windows\syswow64, I said install the INFs. Also, the registry key is different. I'm sorry, but I don't see how you think I copied them. His solution probably works on XP 64bit, whereas mine might not. I did all the work in this thread myself, I just didn't have time to test it because I don't have several different OSes installed.

But i still meet the problem when i was installing inf.

the error is : "the software you are installing has not passed windows logo testing to verify its compatibility

with windows xp."

every inf have the error.

how to solve it?

According to my understanding, use script is the best way. No crack/hack ; just teach that

WMP 10 beta to work on 3790 or something other than XP. The main reason was that

WMP 10 Beta was only written for XP only, they are not supposed to work other than xp.

It's not only the inf files but also....... a long way to explain.........

BTW I'll write a script within 24 hours and post it later. Hope it help.

    • Apple finally brings the slider for Liquid Glass and many other changes by Aditya Tiwari Apple kicked off the official live stream of the WWDC 2026 annual developer event. The company began its latest wave of announcements with changes to the controversial Liquid Glass design language, which debuted last year across Apple's entire software ecosystem. A lot of people didn't like Liquid Glass when it first arrived on iPhone and other devices last year. The devices were plagued with transparency issues and whatnot. While Apple improved things over the year, it has now added a new Liquid Glass slider that lets you switch the transparency from clear to opaque. The sidebars now expand to the edge of the window. When you scroll the UI sideways, the refraction continues beneath the sidebar rather than being cut off at the boundary. Moreover, Apple has changed the way Liquid Glass is rendered across the system. There is a separation between different layers, which makes buttons in the toolbar stand out from the background. Apple said it "deeply appreciates" the feedback it received from users and has made adjustments to Liquid Glass.
    • FWIW, I've been using Helium on Linux and Windows since the first time it was mentioned here. Actually, maybe a day or 3 before, as I searched for it when I saw it mentioned on the MX Linux forums. Haven't had a single issue on either OS. Not bad for a beta.
    • See up until a few years ago y'all could get away with simply denying your war crimes, pretending it never happened. Unfortunately for you, it's the 2020s and Israel's genocide has been livestreamed in real time. You have to be dumber than a rock to think anyone still believes your propaganda. See the cat is already out of the bag. The world already knows who you are so do yourself a favor and just drop the facade. Bet it gets real tiring keep track of all the lies. Take some inspiration from Israeli ministers who boast on live TV they like massacring civilians. Every zionist accusation is after all a confession.
    • He's just reporting what Microsoft posted. https://msmessagecenter.com/MC1381119 It just means that Windows Defender updates will no longer be bundled into the monthly Cumulative Windows security update and will now be a separate download. They'll still be on Microsoft update of course but now they can be released faster.
    • Apple announces iOS 27 with no changes to the list of supported iPhones by Taras Buria At WWDC 2026 in Cupertino, Apple announced iOS 27, the next mobile operating system for compatible iPhones. The update focuses on tweaking and improving last year's iOS 26, particularly in areas like app launch time, Liquid Glass design, and more. Additionally, Apple has reworked Apple Maps with a significantly enhanced Flyover view for a much more realistic view. Apple also promises better performance, smarter search, new Health features, new parental controls, and more. The most important part is that iOS 27 is compatible with all iPhones that can run iOS 26. That means that even the seven-year-old iPhone 11 can run iOS 27 (supposedly better than iOS 26). iOS 27 will be available this Fall, with the first developer betas expected later today. You can follow the live stream here.
