As others have pointed out .... obtain a legal license or revert to the software for which you were legally licensed.
I very much doubt the mods will condone discussion of any license circumvention techniques.
Yes I know, "why should I pay the dark evil Microsoft more money" ..... well, believe it or not a lot of hard work, both pre-release and post-release is required to come up with complex software such as Microsoft Windows. If Microsoft software is your weapon of choice, PAY FOR IT !!!! Otherwise use an open source alternative.
