If you choose to install them Windows 10 to the disk where there is already an existing one installation, το πρόγραμμα εγκατάστασης θα μετονομάσει τον φάκελο των παλιών Windοws σε Windows.old στο root του δίσκου σας. Αυτός ο φάκελος θα περιέχει ένα πλήρες αντίγραφο ασφαλείας της προηγούμενης εγκατάστασης των Windοws 8 ή Windοws 7. Ο φάκελος περιλαμβάνει επίσης το boot manager και τις εγκατεστημένες εφαρμογές σας.
The feature this is very convenient if you plan to uninstall the currently installed version of the Windows and revert to the previously installed version. It can also be useful if you have forgotten to transfer some files or settings in the new facility.
However, if you've finished with all of this, then the Windows.old folder only captures your disk space for no reason.
Below we describe how to delete it using built-in Window tools instead of simply deleting the folder from Explorer.
Press the two Win + R keys together and type the following command in the RUN box that will appear:
cleanmgr
Cleanmgr will appear. Right-click on it and select "Run as Administrator". When the application opens, wait for it to finish calculating your disk space.
Scroll down, at the end of the list of options you will find the option to delete the previous Window installation. Select it and click OK.
You're done, of course you can also delete the C:\Windows.old folder manually, but Disk Cleanup will automatically resolve the permissions access of NTFS and will delete all files that are not accessible from your account.
In the event of a manual deletion, you must resolve these permissions, otherwise you will not be able to delete all the files in the C: \ Windows.old folder.
