However, files and data will not be deleted, and instead they are moved to a new folder called C:\ windows.old. Choosing “None” deletes everything, including all of your apps, and replaces your current version of Windows with Windows 8.1. Obviously you’d want to keep at least some of your files, settings, or apps, otherwise you would have chosen a brand new installation, wiping your existing one. There are several options from which to choose, depending on your existing configuration. Reminder: When performing the upgrade, you need to select what you want to keep from your existing Windows installation.
WINDOWS 10 RECLAIM DISK SPACE UPGRADE
Note: Once you perform an upgrade from Windows 7 or Windows 8 to Windows 8.1, you can no longer revert to your older installation. You will need to reinstall your computer with the previous OS from a recovery disk or from the original media provided by the manufacturer.
But while that is a good thing for the end user, the setup program does not tell the user that so much disk space is now been taken from the C:\ drive.
WINDOWS 10 RECLAIM DISK SPACE INSTALL
The reason for this is that the Windows upgrade setup process automatically stores a lot of your previous Windows install information in a special folder for the purpose of being able to recover this information later. So you upgrade your computer, and after that process is over you take a look at the amount of free space you’ve got on your computer’s C:\ drive and you are startled to find that the amount of free space was reduced drastically. Yes, right now we’re dealing with Windows 8.1, but this was also true for previous versions of Windows, and it may also be true for future versions (although we don’t have control over that, do we?). Later, you decide to upgrade to Windows 8.1. If you look at your personal user profile, you will see that it takes that much disk space, which leaves you with that much free space on those partitions. Let’s say that after using that computer for a while that hard disk partition gets filled up with your personal stuff, whatever that may be.
Let’s assume you’ve got a computer running Windows 7 or 8, and that computer has one internal hard disk that is partitioned into one or more partitions.
