Example scenario:
Let say I work simultaneously at multiple companies as independent contractor throughout the year.
Every company supplies a test PC without OS, solely for my use as test machine.
1) At start of my term, I install the OS and activate it with a product key from MSDN.
2) At end of my term, I need to reclaim back that activation key.
3) repeat, starting at 1
Basically, I don't want to end up in a situation when I cannot re-activate online using the key...
Will 'slmgr.vbs /upk' do the trick?
Or will it eventually be flagged as being repeatedly activated-then-deactivated too many time?
