Windows Activation Problems

I do a fair amount of writing involving Microsoft products.  As such I’m constantly re-installing Windows into virtual machines.  One of the items that catches me off guard is Windows activation with multi-activation keys (MAK) from Technet.  Here’s my friendly reminder on what needs to be done in order to activate when Windows indicates there’s an activation problem:

slmgr.vbs /ipk <WINDOWS KEY HERE>

Windows activation will work after that command completes successfully.
