I did this a long time ago and I decided a lot of people probably don't know this is possible so here is a simple method. Go to this webpage http://webpages.charter.net/krumsick/ and download the KeyTweak program. It will allow you to remap or disable any key on your keyboard. It is self explanatory in use so just disable your left and right windows key, click apply and choose yes to restart. It will update your registry with null values for those two keys. Enjoy no more accidentally pressing those two stupid fucking keys! :yay:
Or if you're not lacking common sense, just pop the offending keys off your keyboard, or better yet just learn not to press them accedentally.
Alright guess your all fags, i know to not press it just I have no purpose for it and popping it out makes your keyboard look like shit.
