Actually I upgraded from windows 1809 to 1903 or something and 1903 had weird graphical glitches as well as my colors being messed up so I reverted the change and went back to 1809, I believe that's when the desktop lag started.
With windows 10 and these types of problems, I have learned that doing these things first is always a good idea to make sure there are no problems with the Windows install, these problems can persist if you don't do a clean install:
1. Open Start.
2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
3. Type the following command and press Enter, let run until its complete:
SFC /scannow
4. Type the following command and press Enter, let run until its complete:
DISM /Online /Cleanup-Image /CheckHealth
5. Type the following command and press Enter, let run until its complete:
DISM /Online /Cleanup-Image /ScanHealth
6. Type the following command and press Enter, let run until its complete:
DISM /Online /Cleanup-Image /RestoreHealth
7. If step 3 failed but steps 4-6 found corruption and fixed it repeat step 3 again.
Report back when this finishes (5-10 min)
