The new Windows 10 May update version 1809 is available to download. I recently updated my PC and Laptop to the latest version. After the update, I saw that a large amount of storage had been filled with Windows.old folder.

In my PC, it was something around 43GB, and the Laptop had 14GB. In these both computers there is a limited amount of disk space available for the Operating System (from 250GB SSD). Space is precious when you have a little one. That’s why I decided to delete that folder.

Every time, I tried the traditional way to delete that folder, it won’t delete. Every time it shows an error. If you have recently updated your Windows PC, then you should know how to delete Windows.old folder in Windows 10.
