Windows 8.1 Disk Usage 100%

    Windows 8.1 Disk Usage 100%


    After a system restore on my laptop, the Disk Usage has been stuck at 100%. I've browsed the internet and tried every-which solution to no avail. Would anyone happen to know a way of fixing this without solutions like "disable BITS" or "check the Resource Manager" - I've never had to deal with the resource manager and find it somewhat intimidating to say the least.

    Thanks for any and all help.

    First go to Disk Clean up right click and run as Administrator and when it's done place a check next to everything and clean your system (it can take quite a while). Then go to Defragment and Optimize Drives and defragment everything... shut down(not restart) and reboot 3 times This cleans and organizes your disk. The 3 reboots lets windows put all programs and start files to the beginning of your C: drive on the outside of your disk.

    Thank you for the help, Cliff, but I'm not sure if it will get the job done; not because I doubt you, but instead because I got an error, and when troubleshooting, found I needed to open Command Prompt (admin) and run sfc/scannow to fix the issue. But... ANOTHER issue rose up - not only is the scan taking a long time, but it froze twice. Once at 39%, and another at 47% (restarted the system after the first freeze)

    Would there happen to be any other ways that you could recommend to help?

    Try this general "Fix All" in the Admin command prompt(it takes quite a while to finish):

    Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow


    It cleans up and restore the WinSxS (Windows Side by Side) folders containing multiple copies of dll‘s in order to let multiple applications run in Windows without any compatibility problem.

    Error: 87

    The online/cleanup-image/startcomponentcleanup is unknown.
    For more information, refer to the help by running DISM.exe /?.

    The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

    And now the system scan is beginning.

    Error 87 means spaces in the code were forgotten/missing. Did you cut & paste it into the command prompt, because I just tried it to check and it starts without error.

    Ah, no. I was reading off of my phone. I'll go ahead and not trust my eyes this next time.

    Don't worry that happens to me too when I'm reading code, that's why I use cut and paste. It has to do with the letter spacing so each line of text is about the same length. In LibreOffice one can change how characters are spaced.

    If you start Task Manager and sort processes by Disk activity, it should tell, which one is responsible.

    It does, but, it says System is to blame, so, I had no idea where to go from there.
