This article will explain in detail how to delete the original system residual C disk memory after upgrading Windows10. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The first step in installing the system is to clean up the previous installation residue. This operation is only for upgraded users, of course, friends who reinstall the system can also operate it.

First of all, let's talk about why there are installation residues. Generally speaking, after the Windows 10 upgrade, the previous program will be retained, but some files of the system will be replaced.

The replacement process does not delete the original system files, but is packaged in a folder called Windows.old. Because if there is a problem with the upgraded system, you can also restore to the previous system through these old system files.

However, this folder takes up a large amount of hard disk space, and if there is no problem with the upgraded system, then this folder is of little use. The most direct way is to delete this folder directly, but because it is a system file, there are some files that cannot be deleted.

In addition, there are some installation residues that you can't see. Windows 10 updates more frequently, so downloaded update packages will be retained, these update packages are large and small, timely cleaning can also free up part of the hard disk space.

These files are stored in specific folders, and these folders are hidden and are generally difficult to find.

Clean up these two parts of the installation residue, the method is the same, do not need everyone to download a variety of security guards, optimization assistant, just right-click on disk C, select properties, in the middle of the pop-up page below the position of "disk cleanup".

Click to enter the disk cleanup program, do not click OK at this time, click "Clean system Files" below, at this time, the cleanup program will scan all the installation residues, including previous versions of files, update packages, and so on. Then you can check all the listed items (the Recycle Bin according to your personal situation), and then click OK.

Wait a moment, the installation residue in the system will basically be cleaned up.

In fact, the built-in cleaning function of Windows is good at cleaning up the system garbage, which basically keeps users away from all kinds of cleaning assistants.

Of course, Windows 10 also has many small features, as long as you master it, you don't need a security guard. Since the author upgraded to Windows 10, I have never installed anti-software or guard again, and there is no problem with using it. Therefore, good habits and a certain basis of operation are very important.
