Running disk cleanup can free disk space. I have also found that running disk cleanup can also boost performance and reduce sluggishness.
Disk cleanup is not available in the apps list in Windows 8.1 but can be found in administrative tools.
Here are the steps on running Disk Cleanup on Windows 8.1
- Go to your apps list by clicking the down arrow on the Home screen
- Search for ‘control panel’
- Click control panel
- Search for administrative tools and click on it
- In the administrative tools windows, search for and click disk-cleanup
