When you upgrade to a new “build“, τα Windows δημιουργούν ένα φάκελο με όνομα Windows.old που περιέχει όλα τα αρχεία τους συστήματός σας από την “παλιά” εγκατάσταση των Windows. Αυτό σας επιτρέπει να “επιστρέψετε” στην προηγούμενη έκδοση των Windows 10 αν κάτι δεν πάει καλά με την εγκατάσταση της νέας έκδοσης.
However, this folder contains more than 10 GB. Windows will automatically delete it after 10 days, as mentioned above, but you can delete them immediately if you do not want to wait.
You should know that you can only delete these files if your computer appears to be working properly. If you have a problem with the new version of Windows 10, you will not be able to "go back" to the previous version.
How to delete the Windows.old folder:
If after a few days everything works correctly, you can delete the old files. The Windows.old folder because it contains files on your old system can not be deleted manually.
With Windows 10 April 2018 Update, you can delete files using the new tool “Free space” in Settings. Follow the route:
Settings - System - Storage - Free Space

Select other types of data you want to delete and do click to delete files.
