As an administrator of your computer, you can easily create or delete user accounts. But did you know that even deleted, the user folder still exists and that it contains all of its preferences? A little trick will allow us to shave these recalcitrant account files.
We will permanently remove user preferences from an already deleted user account. A very good way to do a good cleaning in your PC.
Open the start Menu then right click Properties on Computer.
In the new window that has just appeared, click on Advanced System Parameters. In the section User profile, click on Parameters... This is where the various user accounts are listed. You will notice that on the example of the screenshot, the profile is unknown. This means that I have deleted the user account but that the files concerning it — including application preferences, are beautiful and well-present.
All we have to do is click on the button Remove then to validate the whole by clicking on OK.
Depending on the case, several GB can be recovered following the final disappearance of the remains of a user account. A good way to save disk space especially if your PC is multi-user.
