Fixing things in place in windows is a nightmare for the most part. Users are dumb fucks. Power users and admins are mostly the same. With a consequence that when you have a real obscure problem, there is no documentation by anyone anywhere. Certainly not microsoft with their posh 'documentation' that really doesn't explain a thing.
Doesn't really help either that they change things with every minor update. And their basic structure is one big mess of mixed environments and totally diffferent visions. Let's not even talk about their scripting language where nothing has standard behaviour.
Ffs I hate microsoft. I've been managing that piece of shit for way too long.
