Sorry to butt in here ,
but I didn't know that windows had a set number of times you could install it.
My windows 7 ultimate doesn't give any limitations on installs , on the box or the paperwork.
And it also says you can activate it by internet or phone.
Windows wants you to in reality buy a new copy everytime you install but that aint gonna happen for most lol. So they just want to know how many computers are installed with your copy of it and their happy.
