The whole point of this blanket license is so that, if govt tries that trick again in the future, MS can say that all software in question is legally used, without even having to look at it. Hence there would be no grounds for a lawsuit.
Though something tells me that they'll just start looking for pirated Photoshop etc from now on.
Actually, What it seems like they did was that they went to the local MS lawyer and said "There's illegal software on this computer ... RIGHT?
at which point the MS lawyer either blindly says that it's illegal or (at best) prevaricates. 4-8 months later, if the organization manages to prove that everything is legal, they will hopefully get their machines back.
This was easy to do in the past because "everybody knows" that everybody runs windows, and few people in Russia have legal licenses. Now, even if they claim that it's an illegal copy of photoshop, they now have to actually look at the machine first -- or plant the software, which is even more work....
And some people, by now, hopefully know to download GIMP, if they want to stay one step ahead of (corrupt) law enforcement.
