I cannot think of any good reason why that happens. But take an image of your C partition with free Macrium and then delete them in WinDirStat. Delete them to the recycle bin - then you can always recover them for a little while. And you still have the image once you deleted them from the recycle bin.

I myself have deleted the biggest .msp files from my system and nothing happens - the system runs as usual. As far as I know, the system will recreate those missing .msps in case it needs them again.
