## Verify Authenticity Of Files

You can use the [file hashing method](https://en.wikipedia.org/wiki/File_verification) to verify if a file is genuine. This can be done using tools like [7-Zip](https://7-zip.org/) (After installing 7-Zip, right-click on the ISO file and go to 7-Zip > CRC SHA).

Microsoft publishes a checksum list for consumer editions of [Windows 11](https://www.microsoft.com/software-download/windows11). The checksum lists for other Microsoft products aren't public, as these are only available to subscribers of [MVS](https://visualstudio.microsoft.com/subscriptions/). However, there are many places where you can find these checksums. Examples can be found below.
 -  [files.rg-adguard](https://files.rg-adguard.net/search) (the most complete collection)
 -  [MVS dump](https://awuctl.github.io/mvs/)
 -  [genuine-iso-verifier](https://genuine-iso-verifier.weebly.com/)
 -  [msdn.rg-adguard](https://msdn.rg-adguard.net/)
