Product key needed often

[Louise]

I have Office 2010 Home and Student. Purchased it one year ago and at least 50 time since then it has required me to input the product key number AGAIN. Why does it do this and is there a way to stop it. Each time I get a great idea for a article, story or book in my head, I run to my computer, open Office - - then have to stop and put in the product key and wait while it configures again. By that time, the great idea I had is poof......gone.

Hi Louise,

Evidently there's a fault in your Office activation/configuration. Have you tried repairing your Office installation? You do this via 'Programs and features' in the Windows Control Panel. See also: http://support.microsoft.com/kb/919895
Alternatively, if you previously had a different version of Office installed, see:
