The main reason for this problem is running Disk Cleanup without administrator rights. Other reasons include old error reports left after failed updates or broken entries in the registry at: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches.
1. Run Disk Cleanup as Administrator
In most cases, this issue is caused by not running Disk Cleanup with admin rights. Many users have fixed the problem simply by launching Disk Cleanup with administrative privileges. Without admin access, Disk Cleanup can’t remove some system files.
2. Manually Delete the Files
If running Disk Cleanup as an admin did not work, try deleting the System Queued Windows Error Reporting Files manually. Some users found that after manually deleting these files from their folders, they no longer appeared in Disk Cleanup.
3. Fix the Windows 7 and 8 Log File Bug
If you’re experiencing this problem on Windows 7 or Windows 8, it may be due to a well-known bug that Microsoft hasn’t fully fixed yet. When this bug happens, certain log files can grow extremely large. Unfortunately, even if you delete them, Windows may create them all over again, sometimes even more quickly than before, until your drive is full. There is, however, a manual fix that has helped many users stop this from happening. It involves stopping the Windows Modules Installer service and renaming the log files, so Windows doesn’t keep making them bigger.
4. Perform a Repair Install
If none of the previous methods worked, it may be because of underlying system file corruption. There are several ways to repair system files, but we recommend a Repair Install, because it’s quick and often gets the job done. A Repair Install will reinstall all Windows components with fresh copies, but will let you keep all your personal files, settings, and installed applications. If you decide to proceed, you can follow our step-by-step guide (here).
