The authorisation process Windows imposes on its users is pretty picky, sometimes causing problems with legitimate copies. What do you do when you follow the rules and Windows authorisation still fails you?
I've seen a handful of readers make fun of me for running a non-genuine copy of Windows 7, but I actually did purchase it. My serial number will not work because it is an upgrade-only number. Even though I did upgrade, Windows 7 seems to think I didn't and so I cannot authorise it. I've tried over the phone, but I've just ended up waiting on hold endlessly for an actual person when the automated system failed as well.
That's one circumstance. Other problems include Windows refusing to activate after a hardware change, receiving "Invalid Data" errors for unknown reasons, and Windows forgetting that it's activated every time you reboot. So how do you deal with activation troubles? Obviously this can be worked around by cracking Windows and using it pseudo-illegally, but there most be a better option for dealing with these types of problems. When Windows and Microsoft support fails you, what do you do?
And while we're at it, how do you solve issues with other software that has frequent authorisation problems? Windows is certainly not the only software with overly-picky copy protection. Share your creative solutions in the comments.
