On an old system that I haven't started up for some time I got this
message at the lower right of my screen. I searched for a fix and came
upon this

As it says I used the CMD (run as administrator) and entered SLMGR
-REARM and hit return. I rebooted and all was well. Now a few days later
I get the same message. Is anyone familiar with a direct fix? I've read
about other fixes but I'd like to get a first hand account of what
really works to set this installation straight.

Thanks for any suggestions.
