When your hard drive runs low on space, your computer slows down, applications may crash, and updates cannot install. Windows needs at least 10 GB of free space on the C: drive to run properly. These steps help you reclaim space safely.
Step 1: Check Available Space
Open File Explorer, right-click the C: drive, and select Properties. The pie chart shows used and free space.
Step 2: Use Disk Cleanup
- Search for Disk Cleanup in the Start menu and open it.
- Select the C: drive and click OK.
- Check the boxes for Temporary files, Recycle Bin, Thumbnails, and Temporary Internet Files.
- Click Clean up system files for additional options, including Windows Update Cleanup (which can reclaim several GB).
- Click OK and confirm the deletion.
Step 3: Empty the Downloads Folder
Your Downloads folder often accumulates installers, attachments, and files you no longer need. Open File Explorer > Downloads, review the contents, and delete files you no longer need.
Step 4: Use Storage Sense
Windows can automatically manage space. Go to Settings > System > Storage and turn on Storage Sense. Configure it to automatically delete temporary files and files in the Recycle Bin after 30 days.
Do Not Delete
Do not delete anything from the Windows, Program Files, or ProgramData folders. If you are unsure about a file, leave it alone and submit a ticket.
