The Greatest Checklist to Clean Your Windows Personal Computer


Our personal computers tend to slow down over the course of time. The biggest culprit for this is inadequate OS maintenance. However, by taking some time cleaning up Microsoft Windows, noteworthy results can be noticed.

Unused Software Deletion

To begin cleaning up your Windows personal computer, remove software no longer used. To accomplish this, head to Start>Settings>Apps>Apps and features. Anything you no longer need, click Uninstall. Be careful not to remove anything you are unsure of.

Antivirus Scan

A common culprit for a slow machine is viruses. Locate an option called or similar to Deep Scan or Full Scan on your antivirus. This option is more thorough and takes longer than the common scan.

Disk Cleanup

Next on the list is to run Disk Cleanup, a tool that has been a part of this OS for numerous years. Start by heading to Control Panel>Administrative Tools>Disk Cleanup. You can also reach it by entering Disk Cleanup in the Start Menu.

Once open, select Clean up system files to ensure a more thorough scan is ran. Normally, you would select OK after selecting each box next to the result type. However, it is important to note that while using Clean up system files, if you select the box next to Previous Windows Installation, you will no longer be able to roll back to Microsoft’s Windows previous version.

Hard Drive Defragment

The OS controls disk defragmentation in Windows 10 when it senses it is needed. But, to ensure a proper cleanup of your personal computer, it is best to run it manually.

Head to Control Panel>Administrative Tools to locate Defragment and Optimize Drives. Highlight the primary hard drive then select Optimize.

Old Program Files Removal

Small amounts of old app files can be found in folders of Program Files. These can be found at C:\Program Files as well as C:\Program Files (x86).

While carefully going down the list, remove any files and folders not used anymore on your personal computer.


Most people have heard terrifying stories in regard to registry cleaners, regardless how popular some are. However, maintaining a clean registry is important. If deciding on cleaning the registry yourself rather than using a third-party software, perform a search for regedit followed by hitting Enter. Head to Computer\HKEY_LOCAL_MACHINE\SOFTWARE as well as Computer\HKEY_CURRENT_USER\Software. Locate and remove entries for software no longer in use on your computer. Be sure to read the warning below before removing any entries.

Warning: Profound consequences for your Windows system can occur by removing the wrong registry entry. Prior to proceeding, it is vital for you to create a complete backup of your registry data.

You are sure to see a significant increase in speed after completing this list and making sure you know the best Windows tips out there!
