I may be having the same problem. Although I haven't run a video on it, every time I try to rate the system it hangs on "assessing windows media decoding performance". I also have a low end video card on a Lenovo X41 tablet (Intel 915GM).

Yep, that sounds like exactly the problem we're having.

And an update: I was wrong, VLC player *can* play video without it locking the system up. Still, I really hope this gets sorted out for low-end hardware because Windows 7 really seems like it'll run well, otherwise.

Ok, so VLC has given me some good info to help figure out where the problem is. It's a problem with DirectX acceleration, and contrary to what I thought, it's just the display that locks. Or at least the sound keeps playing in VLC.

Anyway, what I did was go into the video preferences and try different output options. DirectX 3D acceleration worked, but just DirectX acceleration caused the lock we've all been experiencing.

So does anyone know of a way to repair fireplace the version of DirectX we're using so it might be compatible with lower-end hardware?

Ugh. Im starting to think that my GPU is just too outdated. There is not even VISTA support for the ATI Mobility Radeon 9200. If I could get a working Vista driver all bets would say it would work with Win 7.

Anyone getting any traction with this issue?

I still have 6956 on another partition but unfortunately Build 7000 doesn't give me a boot manager to access it. Any ideas how?

If you assign a drive letter to the partition (or it already has one), you can try using EasyBCD. Although it was made for Vista, Windows 7 has a very similar boot manager system, so you can run it with "Run As Administrator" and/or "Vista Compatibility". Without those enabled, running it completely locked it up.

I had a Radeon 9250 256mb PCI and had the same problem. I know that the problem did not occur until build 6956. I don't quite remember, but I think I got it to work with a modded driver.

Look at this list: http://downloads.guru3d.com/download.php?id=24

I used the NGO driver (v1.6.6), but if that doesn't work you might want to try some of the others. Just remember that since support for R200 GPUs was taken out of catalyst in 6.7, you can only use drivers based on Catalyst version 6.6 or earlier. You may also try to install the driver with "Run As Administrator" and "Vista Compatibility"/"XP Compatibility".

I've also noticed that even though I've upgraded to a Radeon HD4830, it locks up randomly when I use Google Chrome....

I'll give another shot to getting a vista driver to work with my Geforce4 Go 420 32mb. I think the problem could be the XP vs Vista display driver model , and maybe even something to do with WARP (the DX10 software rasterizer).

Of course, if this does fix *this* issue, then I've got to try to find a way to fix rotation for my tablet. But one problem at a time.

But I am going to wait until I get the public beta later today before I do anymore fiddling because I've done a lot of regedit-ing and fiddling with dx files while trying to make this work, and I'd like to start from a clean install.

Since this is video card related I'll post this little weird thing. I tried it on a laptop with an ATI mobile X1400 card. It downloaded an updated X1400 driver from Windows Update but I wasn't getting Aero so I ran the Assessment Utility. The card came back as a 1.0 with no Aero capability. I knew the card wasn't that bad. On a whim I decided to download the Catalyst drivers from the ATI website expecting them not to work on a laptop like they haven't in the past. They installed fine and my video rating went up to 3.2, which enabled Aero. Is ATI not locking out their mobile chips anymore?

Ive spent the last 4 days playing with various Catalyst versions, custom driver files, etc to no avail at all. I simply think I will never gain support in win 7 due to outdated hw :(. I have an ATI Mobility Radeon 9200.

No Aero, PC comes back as a 1.0 :(!!! :( Windows Update installs some BS Mobility Radeon 9000 WDDM driver that cuases my display to go nuts!

Here is the driver info installed by MS. On my screen when that driver is installed i have lines EVERYHWERE and a double immage. I dont know where else to look for help on this issue.

I'm having the same problem with 7000. Any avi video I play hard locks up my laptop. I wasn't having this problem in 6801. I'm using a Dell XPS laptop with intel 915gm graphics card. Everything else runs great so this is a huge bummer and the only reason i haven't moved completely to 7.

Not sure, guys, that this'd help, but because I needed to watch :) some TV series and was too lazy to switch back HD with Vista, I did the following to make .avi work (after numerous freezes). Disclaimer: it is case-by-case basis and more of an example rather than a solution... I myself waiting for a more constructive solution

- install old drivers for my old Mobility Radeon 7500 (it is even older than most of you have) and I used, I think, XP's WDM drivers from Mobility Radeon 9000.

- uninstall latest Vista codec pack (because someone above said that W7 already has good package of its own)

- install VLC player, go to Preferences --> Video and turn off acceleration

- associate avi with VLC and start video...

the following happens: in windowed mode audio is present but no video at all (not even sluggish), then I make it full screen and video runs fine... It does work and with no problems, delays nor lines.

there is a catch, on several occasions I tried scrolling through video and it caused freezing when I tried double click in full-screen mode to return to video and also when I tested played video by scrolling back and forth. So there are certain bugs still present, however it is at least something to get started... try it out as a temp measure

dont give up on W7, like I was about to (cause being able to watch video is important for me)

I did not try playing DVDs, only avi/mpgs

So what driver is everyone using for the Intel 915GM? I'm using the default one that build 7000 installed. I can't find another compatabile one. It's only reporting 8MB of memory. Any help is greatly appreciated. I'm very happy with the performance of the OS right now.

Thanks

I got video to work with vlc WITH accelereration, as I mentioned above--as long as I don't pick directx (though directx 3d works).

I've tried a lot of vista drivers from laptopvideo2go, and those that install give me a code 43 error (something about windows detecting a problem and stopping the device).

VLC is a good work around, but I really hope this is fixed for the RTM version. Let's all report it as a bug in the meantime

How about codec packs, are they present (did you install K Lite or Vista Pack)?

I also commented on your other post. No DirectX 9 compatible GPU = No Aero.

I get laggy video playback in fullscreen. Don't ask me why, but i've always had this in Vista+7 now. Only real work around i had (to Windows Media Player/Winamp[for video playback as well]) was to use media player classic from www.cccp-project.net. That works fine and some how got windows media to play videos fullscreen without lag. Now all that remains is Winamp tho, i can live with mediaplayer/classic for vids :)

Video drivers

Systems which use XDDM drivers may completely stop responding in certain scenarios. The computer will not respond to CTRL+ALT+DELETE and you will have to cycle the power to restart the computer, with the attendant risk of loss of unsaved data.

Some activities which have been demonstrated to trigger this issue include, but are not limited to:

Using Winsat.exe or using the Rate and improve your computer?s performance tool.

Changing multi-monitor configurations

DVD or other video playback

To avoid this, do not use XDDM drivers, but find an appropriate WDDM driver instead. If your video chipset does not have a WDDM driver (such as the Intel 915), use a VGA driver or an GPU that supports WDDM drivers.

If this issue occurs at setup, either avoid unattended setup or uninstall the XDDM driver and use a VGA driver until setup is complete.

XPDM vs. WDDM

This may help if you have WPF problems...

Disable WPF Hardware Acceleration:

DWORD HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration = 1

I may be having the same problem. Although I haven't run a video on it, every time I try to rate the system it hangs on "assessing windows media decoding performance". I also have a low end video card on a Lenovo X41 tablet (Intel 915GM).

I'm using the same computer and having the same issue. Mine also locks up in Explorer when I browse a folder with AVIs, and some other instances.

In my case, setting the hardware acceleration slider to the third notch (from the left) resolved the issues. This notch is the one with the "Disable all DirectDraw and Direct3D accelerations" description. Obviously the graphics performance goes to crap, but at least the system remains usable, and the performance should still be better than with the default VGA driver. Also, doing it this way preserves the screen rotation feature, important for tablet users.

Might be a little late, but I was having a issue with this too - it doesnt lock up per-se, but instead had a second or two where the video would run at 5fps or so, then go back to normal.

Anyway, in ure device manager, chances are your missing a driver for sm bus controller. I found that downloading the drivers and installing them seemed to make that problem go away, and the video lag is now gone.

The drivers are located here: http://uswave.net/windows7/intel-smbus-drivers.zip

I hope this helps you all, haven't tested on any other machine, but I know it works with my specs in sig.

    • I'm still on Windows 10 22H2 because I didn't want to deal with all the issues in Windows 11, so I waited almost a week before installing the latest Patch Tuesday update (KB5094127), I went ahead and did it, and it was a huge mistake—ever since then, my File Explorer has seen a performance drop of about 30% when transferring large files... Once again, Microsoft has outdone itself! This update cannot be uninstalled, either through the Control Panel (via Settings) or by accessing Advanced Startup Options. The only possible alternative would be to use system restore points, but I’d have to reinstall all app and driver updates (and there’s no guarantee it would work). Or there’s the “nuclear option” of a in-place repair without losing files or apps, but even then, all my customizations would be lost! Microsoft just can’t help but mess everything up! Way to go, Microsoft! But I still don’t want your c****y Windows 11!
    • Microsoft: Windows 11 could finally solve a major issue across AMD, Nvidia, and Intel GPUs by Sayan Sen While Microsoft has been trying to improve it, Windows 11 is definitely not flawless, as even today some issues are taking a year to publicly acknowledge. However, one area of trouble that may finally see much better results soon is graphics driver crashes. Work on graphics driver timeouts, also called Timeout and Detection Recovery (TDR), is not new as the latest WDDM 3.2 also has specific improvements regarding it. Windows Display Driver Model (WDDM) version 3.2 is supported on Windows 11 24H2 and 25H2. However, with the upcoming version 26H2, TDR crash diagnosis could go to the next level as Microsoft is introducing a new DirectX 12 API feature called "DirectX Dump Files". Similar to how system memory dump files work when a system crashes or freezes or encounters any such major issue, DirectX Dump Files (DDF) will essentially record a snapshot of the GPU execution right at the moment a graphics-related crash or hang or freeze occurs, so that developers can better understand and diagnoze these TDR and timeout detection errors. The dump will be available as a .dxdmp file for analysis and it will be a comprehensive dump file generated with detailed insights about the hardware, drivers, Windows, as well as the affected application. This should be another welcome change in this department. Earlier at GDC 2026, when the technology was first debuted, Microsoft had shared more details regarding it. The company had explained how DDF is designed to gather data from every layer of the graphics stack into a single file, eliminating the need for developers to manually correlate logs from multiple tools. As mentioned above, the dump can contain a lot of useful details like GPU hardware state information such as register values, shader program counters, page fault virtual addresses, shader memory data, and command buffers. Alongside that, it also captures DirectX runtime and kernel information, including D3D objects, pipeline state objects, device error data, adapter details, and CPU call stacks. Microsoft says the feature has been built around two primary use cases: retail device removals and local device removals. The former allows developers to collect crash information from end users' systems in the field, while the latter helps QA teams and developers investigate issues on test machines. Developers will also be able to include up to 2 MB of custom application data through new D3D12 APIs, providing additional context for troubleshooting. In addition, Microsoft is introducing three dump collection modes ranging from zero-overhead capture, which has no runtime performance impact on supported hardware, to higher-detail modes that collect more vendor-specific debugging data. On compatible Tier 2 hardware, zero-overhead dumps will be enabled by default, meaning developers may begin receiving useful crash diagnostics without making any code changes. The table below explains the three tiers: Tier Description NO_OVERHEAD Enables crash capture with no runtime cost and is suitable for broad deployment MEDIUM_OVERHEAD Provides a balance, capturing additional diagnostic data with moderate impact HIGH_OVERHEAD Collects the most detailed GPU and driver state available, enabling deeper investigation at the cost of higher runtime overhead In terms of availability, the company expects broader release to be around the fall of 2026, which should be right around the time when Windows 11 version 26H2 lands. Right now, DirectX Dump Files are available as a preview and currently, only AMD has the compatible AgilitySDK Developer Preview driver version 26.10.07.02. You can find the official announcement post here on Microsoft's website.
