Low Disk Space error due to a full Temp folder

If you used Disk Cleanup to free up space on your device and then see a Low Disk Space error, it’s possible that your Temp folder is quickly filling up with application (.appx) files that are used by Microsoft Store. To fix this problem, you’ll need to reset the Store, clear the Store cache, and run the Windows Update troubleshooter:

  • To reset Microsoft Store, select Start  >Settings > Update & Security > Troubleshoot, then select Windows Store Apps from the list and select Run the troubleshooter.
  • To clear the Microsoft Store cache, press the Windows Logo Key  + R to open the Run dialog box, then type wsreset.exe and click OK. A blank Command Prompt window will open, and after about ten seconds the window will close and the Store will open automatically. 
  • To reset Windows Update, select Start Settings  > Update & Security  > Troubleshoot, then select Windows Update from the list, and select Run the troubleshooter
