Ed Bott writes about scripts from Massgrave to activate Windows, change Windows version, e.g., home to pro, enable Extended Servicing, activate Office etc. Note that while Ed says the scripts looked harmless from a malware perspective, since it's been publicized on ZDNET, cyber criminals are most likely actively trying to breach their site etc. to alter those scripts, so be careful.
