Other Things You Can Do to Improve PC Performance

Using a PC cleaning program is not the ultimate solution for a lag-free computer, but developing healthy usage habits and conducting maintenance regularly is. Here is how you can manually manage your computer space and improve the overall performance of your device.

Regularly Delete Temporary Files

Temporary files, including caches, logs, sessions, and more, are created by the device system or apps to store data temporarily. You can find and manually delete these files on C:\Users\AppData\Local\Temp.

Uninstall Unused Programs

Go to “Settings” and find “Apps > Apps & features”, find the program you want to uninstall, and follow the instructions to uninstall it. If you failed, try a 3rd party uninstaller.

Manage Startup Programs

Another thing you can do to improve computer speed is manage the auto-startup programs. Open “Settings” and click on “Apps”. Select “Startup” from the menu and toggle the switch to turn on or off the auto-startup programs.

Periodically Clear Browser Cache

Browser cache is another crucial factor in storage overuse. You can manually clear the unnecessary browser data from the 3 dots in the upper-right corner > Delete Browsing Data, select what types of data you want to clear, and click to confirm.

Move Files to External Storage

When all the files are important and can not be deleted, consider connecting an external hard drive to your PC. After that, open your file manager and drag large files to the external drive.

Optimize Hard Drive

Search for Defragment and Optimize Drives in the Start menu. Select your hard drive and click Optimize. (Note: This is mainly for HDDs. SSDs do not require defragmentation.)
