How do I reset WPA completely, and also the default security provider settings?
I've come across a machine which for some reason, is convinced there is a problem with WPA:
The error onscreen is:
Windows Product Activation
A problem is preventing windows from accurately checking the license for this computer. Error Code 0x80090019
After googling around I found the default security provider is probably corrupt and attempted to reset it but this has so far not helped.
How would I go about completely resetting this in order to solve the problem?
