Windows 10 Anniversary Update started rolling out to users this week. It brings great enhancements like improved Cortana, Windows Ink, Improved Start Menu etc. If you performed a direct upgrade from the previous version to Anniversary Update (Version 1607), you should know that Windows reserves old Installation files in case you want to roll out to the previous build. Windows 10 allows you to roll back to the previous build within 10 days if you’re experiencing issues with the current build.
You should go ahead with the article only if you’re not experiencing problems with the current version and aren’t planning to go back to the previous version.
If you are ready, you can save around 25 GB of space by deleting these Previous Windows Installation files. To do this, Disk Cleanup comes in handy. Follow these steps:
1. Open Start Menu. Search for “Disk Cleanup” and click on it to open.
2. Click Clean up system files. Windows will take few minutes and will list all the space-hogging areas.
3. Now scroll through the list and check Previous Windows Installation as well as some other entries like Temporary Windows installation files. After checking them all, click OK and it will start performing cleanup.
In our case, we freed a whopping 33.9 GB of space. Don’t forget to share in comments how much space you recovered.
