How to delete the Windows.old folder
When you install the new Windows 10/7 / 8.1 system not through the BIOS, the system is installed uncleanly, that is, it archives the old system into the Windows.old folder. Or when big updates come in Windows 10, then the old version of the system falls into this folder as a copy. Why is this needed? This is necessary so that later you can restore the previous version of Windows from the windows.old folder if the new one works with errors. This is a kind of backup of your old system. Can I delete the Windows.old folder? Many do not need it, since it can take up a lot of extra space on your disk. And if your system works stably, then in most cases this folder is not needed. But I recommend that you archive it and place it on another local drive so that you can then take separate system files when they don’t work for you. For example, you have an error with a DLL file, and it is dangerous to download such files on the Internet. You go to your archive and look for your file there, which gives an error. In a word, the Windows.old folder can be useful. Remember, deleting this folder, you will not be able to return to an older version of Windows in case of serious problems. Let’s see how to delete the Windows.old folder, even when it is not deleted in Windows 10/7 / 8.1.
