NO STARS! APPEARS THAT MICROSOFT BLACKMAILERWhat started as a useful office tool, Microsoft now appears to be a blackmailer, blocking even OFF LINE software by timed self-destruct on their product Office Home & Student. Purchased by me at John Lewis, and installed by John Lewis with the clear understanding and reiteration that it was a lifetime subscription, after almost two years of use off line, the product is behaving like a blackmailing hacker by locking the 50 years of my Microsoft files. NEVER AGAIN USING MICROSOFT.
