What you need
Steps
Open Settings, go to System, then Storage. Wait for Windows to scan the C drive and review the categories to see what is using space.
Go to Settings, Apps, Installed apps. Sort the list by size, review large programs you no longer use, and select Uninstall next to each one.
Return to System, Storage, then Temporary files. Tick the categories you do not need, such as temporary files and thumbnails, then select Remove files.
In Storage settings, turn on Storage Sense. Set it to run weekly or when disk space runs low, then select Run Storage Sense now.
Open Cleanup recommendations under Storage. Review the suggested files and apps, tick the items you want to remove, then select Clean up.
Search for Disk Cleanup and open it. Choose the C drive, select Clean up system files, tick the file types to remove, then select OK and Delete Files.
Tips and common mistakes
Do not delete files in the Windows or Program Files folders by hand; use the built-in tools instead.
Check Downloads and Documents for large files before running cleanup.
Disk Cleanup can remove previous Windows installations, so you cannot roll back afterward.
If space is still low, move personal files to another drive.
Questions
Will cleaning the C drive delete my personal files?
Built-in tools remove temporary files, caches, and unused apps. They do not remove your documents, photos, or other personal files unless you select them.
How often should I clean the C drive?
Run Storage Sense weekly and check Storage settings monthly, or whenever free space drops below 10 percent.
Is Disk Cleanup safe?
Yes for standard temporary files. Review the list before deleting, and note that removing previous Windows installations prevents rollback.
