MATS folder is a backup folder, deletable!

MATS folder in the root of the C drive

Sometimes, you may find a folder named MATS in the root of your PC's C drive.

In Windows 7, MATS was a backup folder generated when running the system repair tool "Microsoft easy fix," but MATS also exists in Windows 10/11.

Microsoft easy fix was a system tool for diagnosing and resolving issues caused by third-party software affecting Microsoft products. In Windows 10/11, the functionality equivalent to Microsoft easy fix is incorporated as a module within the "Troubleshooting Tool."

MATS can be deleted

When you run the troubleshooting tool in Windows 10/11, it is believed that "MATS" is generated. MATS can be deleted.

Therefore, the conclusion is that MATS is a backup folder.

Removed after follow-up

Renamed MATS to [MATSx] instead of deleting it out of the blue and have been observing for several weeks. So far no problems have been identified.

[procedure]

Rename MATS.（MATSx）
Run Windows for a few weeks and see how it goes.
If no problem, remove MATSx.

Documentation

From everything I am seeing, it should be fine to delete this folder.

That being said, let's rename it first to see if we get any bad behavior. If not, then we can delete it without any risk of harm.
