Windows performance drops in Windows 10/11 due to slow graphics, which improves after ending the dwm.exe service.
Has anyone observed slow performance in graphics—such as dragging a window or reduced frame rates—in games? This issue appears after the computer has been running for more than six to twelve hours, and it disappears when closing the dwm.exe process in Task Manager. The system’s interrupt service also shows spikes intermittently during these periods, though I couldn’t identify the exact cause using Event Viewer. Could you suggest possible reasons? I’ve tried DDU and reinstalled several GPU drivers. The problem began after upgrading from Windows 7 to Windows 10 and continued through Windows 10 to Windows 11. I have an Xeon processor with 8 cores, E5-1660 v4, overclocked at 3600 MHz, 128GB DDR4 2333Mhz RAM, RTX 2070 graphics.
It might be due to an upgrade rather than a fresh installation.
This might just be a factor, but it shouldn’t be the main concern. Upgrades shouldn’t be the first choice. It’s unnecessary to force users to reinstall software. Can we perform a thorough analysis of dwm.exe and system interrupts?
You might want to use system file checker. (SFC) through the command prompt. (Make sure you’re running it as administrator.) You’re on a phone, so look up the SFC command. It will examine and repair all files. This could fix your problem. I don’t know much about root cause analysis for dwm.exe. Sorry. EDIT – System File Checker is a Windows tool that verifies file integrity. To start it, follow these steps: Ensure you have the latest Windows updates installed, then restart your device. For more details, check Update Windows. In the taskbar search, type Command Prompt and choose the desktop app from the results. Click Run as administrator and confirm. Execute DISM.exe /Online /Cleanup-image /Restorehealth (pay attention to the spaces). Then press Enter. (Be aware this may take a few minutes and up to half an hour.) Once you see “Operation completed successfully,” type sfc /scannow (with a space after “sfc”) and press Enter. After that, type exit when prompted.
