If you are searching online how to delete the Windows.old folder on Windows 10, then it means you are taking your computer’s health seriously. It’s important to keep track of all the files that are stored in your computer, especially those that you no longer use but that subsequently accumulate and take up valuable space.

If you’ve ever upgraded your computer from an older version of Windows, then you know that it can be done without formatting the hard drive before the installation of the new system. However, if you still want to do that and use the installation wizard, you should know that it does save a copy of the previous version inside the Windows.old folder. It’s a handy trick, a sort of insurance just in case something goes wrong with the upgrade.

The backup copy is saved on your computer in case there is a malfunction during the installation of the new operating system. This feature is also very useful if you end up troubleshooting something and you will need to regress to the older version to make sure that the system was not compromised. Of course, these kinds of troubleshooting events occur when your computer was already exposed to some malicious software and you did not take preventive action. If that is not the case and you would like to prevent this from happening to your computer, we suggest investing in Auslogics Anti-Malware, a tool that will safeguard your computer from any unwanted infectious programs that can install themselves without you knowing.
