1. Uninstall unused programs and clean up the registry. Go to Control Panel > Programs and Features, and remove programs that you don’t need or use anymore. You can also use a registry cleaner program to scan your computer and clean out any invalid registry entries.
2. Perform regular disk scans. Using the built-in Windows Disk Cleanup tool, scan your hard drive and delete any unnecessary temporary files and caches.
3. Delete unnecessary files. Go through the folders in your Documents and Downloads folders, as well as your desktop, and delete any files that are no longer needed.
4. Run a virus scan. Make sure your antivirus program is up-to-date and run a full scan of your computer. If it finds any malicious files, delete them immediately.
5. Update your drivers. Make sure your device drivers are all up-to-date. Outdated drivers can cause your computer to run slower.
6. Defragment your hard drive. A cluttered or fragmented hard drive can slow down your computer significantly. Use the built-in Windows disk defragmenter to organize your hard drive and improve its performance.
