 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.

+**MVS**  
+On MVS, you need to login and click on 'All Downloads' button and then search the product name.  
+
+**MVS Limitations:**  
+ -	They used to publish only SHA-1, but later started publishing SHA-1 and SHA-256 both and from 2022 they now publish only SHA-256.  
+ -	However they removed all the SHA-1 data and as a result, old files checksums are simply not available on MVS site.  
+ -	Also, around the time when they were publishing SHA-1 and SHA-256 both, they messed up some SHA-256 data, for example 
+ 	```
+ 	Incorrect SHA-256 example
+ 	SHA256: BDB3D0C5C933B201ECE736A172FB604AA5D7D0705DD75681F9FCC4B1EE79FAC8
+ 	File name: en-uk_windows_10_enterprise_ltsc_2019_x64_dvd_723dfbc1.iso
+ 	```
+ -	So its useful only for the latest files.
+
+**Windows 11**  
+SHA-256 list will appear if you download the ISO file.
+
+**Windows 10**  
+Microsoft doesn't allow you to download ISO file directly if browser's useragent is Windows OS. So you need to change it to something else like Android or IOS and then download the ISO file to see the list.
