Final Words

To fix this, we recommend that you:

  1. Check your computer’s disk usage regularly. Windows 11’s Disk Usage report is available in the System Tray and can be found by right-clicking on the report and selecting “Show All Disk Usage.” This report will show you how much disk space is used by each program, application, and data file on your computer. You can also use the “Computer Management” tool in Windows 11 to view and change these settings.
  2. Remove any out-of-date drivers from your computer. Windows 11 includes a number of new driver versions every month, so it’s important to keep your drivers up to date. To do this, open the “Driver Store” in Windows 11 and select “Update Driver.” After updating all of your drivers, restart your computer and check for any changes in disk usage or performance.
  3. Disable background processes that are not needed or desirable. Background processes can cause Windows 11 to slow down or even crash when they start up. To disable a background process, open the “Task Manager” in Windows 11 and select the process you want to stop running (usually “Startup,” “Sysinternals,” or “Windows Update”). After stopping the process, open the “System Properties” dialog box for that process and set its priority to low or none (if it was set as high as possible). This will prevent it from starting up again until it is properly scheduled by another process.
