One solution for freeing up space is to get rid of unnecessary files from old software installations. If you don’t need a program anymore, uninstall it using the Control Panel in Windows.

2) Update your OS

Computers run slow when they are outdated. Make sure you’re using current versions of your OS and software; that means your computer has been updated with security patches, bug fixes, and new features.

Finally, keep your hard drive clean by deleting unnecessary files regularly. This will help prevent fragmentation issues which can lead to slowness down the road.
