    MSE playing silly wotnots

    My wife used her laptop last night and when she booted up, MSE said that Win7 was not genuine. After a bit of huffing and puffing by me (and getting an error on an MS page), it seemed to decide it was genuine after all. Wondering why this happened - I changed the battery a couple of days ago as the old one was getting tired (both MS and Linux said so!). Would this have generated the non-genuine message?

    More likely it's another good old permissions/security glitch.
