Windows 10: dwm.exe error on Acer V5-471 win 10-20h2 home at start-up

t would appear that the DWM.exe error has been around for several years. I will add my own experience to see if anyone who has resolved the issue as I haven't. For the record we are on Win 10 20h2, we have Intel 3000 graphics (eg not a Nvidia issue). The system was originally shipped with Win 8, Acer has not updated any drivers for Win 10/64. note no issues show up on the device manager. No other issues show up in the Event manager. Problem started in 09/20 when we were on 2004. All Win 10 Updates have been installed - we fully up-to-date, including optional driver updates.<br>
<br>
The problem occurs at start up, frequently with screen resetting on start up (flash-like), sometimes freezing especially if the system has been changed, frequently while undertaking the following tests, eg after SFC fixed some issues successfully (but not DWM).<br>
<br>
We tried the following:<br>
Solution 1 Check your computer for malware - Done - no issues<br>
Solution 2 Restart explorer.exe - not applicable as issue is only on startup<br>
Solution 3 Remove third-party antivirus programs - done (&amp; re-installed)<br>
Solution 4 Disable problematic services - done(Google update removed)<br>
Solution 5 Check your USB devices (non present)<br>
Solution 6 Delete the mdi264.dll (not present)<br>
Solution 7 Disable Chrome Pepper Flash extension (not present)<br>
Solution 8 Install older graphics card drivers - Tried, no difference, also tried Microsoft default graphics driver<br>
Solution 9 Adjust Performance settings - done<br>
Solution 10 Run the SFC scan - done<br>
Solution 11 Run DISM - done<br>
Solution 12 Try with the Performance troubleshooter - done<br>
Solution 13 Change the wallpaper/screensaver N/A (standard)<br>
.Solution 14 Disable Hardware acceleration in Office programs - done<br>
Solution 15 Remove Logitech SetPoint software N/A<br>
Solution 16 update BIOS - not possible on this laptop<br>
Solution 17 - rebuild Win10 - not tried as there are reports that this doesn't resolve the problem - a lot of work for no result.<br>
<br>
Anyone got a solution?

Does anyone know why the Aspire V5-471 is not compatible with Windows 10

I am in the process of resetting an Aspire V5-471, that Acer now tells me is not compatible with Windows 10. It has been running Windows 10 since early when it was available. Does anyone know why the latest automatic update of Win 10 suddenly became incompatible
and will not download the network drivers, so will not access the internet in any way.

Hi Daveyk,

Thank you for posting in Microsoft Community. I understand your concern and I am glad to assist you.

I would suggest you to run the hardware and device troubleshooter and check.

Try these steps to run the troubleshooter:

• Type troubleshooting in the search bar.
  
• Click view all in the left panel.
• Select ‘Hardware and devices' and follow the on-screen instructions.
  

Please also update chipset drivers from the computer manufacturer's website
and check the issue.
