I just noticed that the Microsoft Store delivers an EXE with a different hash sum, every time I download an installer from its Store.

For example, try downloading the Windows Calculator twice, you will see that the files have different hashes (It may be necessary to close the browser and delete all browsing data in-between):

For example, I get these two hashes for the "same" installer downloaded there:

And here two different scans for the "same" installer.

Why is MS doing this? It seems this creates unnecessary work for Virus Checkers. It also seems to be a data protection issue.
