How to disable graphics card hardware acceleration introduced in Windows 10 20H1?

Anonymous

Here is an old notebook Lenovo 3000 N200 (0769) with a nvidia GeForce Go 7300 graphics card. Everything works smoothly up to Windows 10 1909 using the old Windows Vista/7 drivers (32bit, 64bit). Since Windows 10 20H1, there have been massive problems with the display of the desktop and Store apps, which also affects Microsoft's own apps like Windows Settings. Old classic desktop apps, e.g. Edge, Device Manager ... are not directly affected by the problems. If the nvidia driver is deactivated and the Microsoft Basic Display Adapter is used, then the aforementioned problems do not exist, but the screen resolution and color depth are severely limited. If the nvidia driver is activated after the Microsoft Basic Display Adapter was active, Windows 10 with the nvidia driver works without problems with full screen resolution and full color depth - unfortunately only until the next reboot.

AFAIK Windows 10 has been using hardware acceleration for apps and desktop since 20H1. Is there any way to turn off this hardware acceleration to have the same behavior as Windows 10 1909?

TIA

Hi Paul,

thank you very much for your reply. Unfortunately, the registry entry does not have the intended effect, i.e. it is still the same error behaviour as before.

This is the exported registry key

Windows Registry Editor Version 5.00 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers] 

"DisableHWAcceleration"=dword:00000001

Hi wasteland,

I'm Paul and I'm here to help you with your concern.

Try to disable Hardware Acceleration using Registry Editor.

*note: I suggest that you create a System Restore point before proceeding.

> Open Registry Editor(press Win key + R > Type and enter: regedit).

> Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

> Right-click GraphicsDrivers.

> click New > Dword(32) Value.

> Value name:= DisableHWAcceleration , Value data: = 1 , Base: = Hexadecimal.

> click OK > close Registry Editor > Restart the PC.

I hope this helps. Feel free to ask back any questions and keep me posted.
