Or you could take a slightly different hardware approach.
Pop off the left windows key, glue it so it can't depress, wait till the glue hardens, replace the key.
As noted above you can still control esc to get the same function, or use the right win key which for some reason doesn't seem to be as bad.
Any way you want to do it, its on your hardware, so its your responsibility.
No point in getting angry about it, or expecting someone else to fix it.
