I'm at the process of changing some of my PC names (mainly as I'm installing Windows 8), and as far as I can tell, registration is done with the PC name (I changed my work PC's name and Take Command asked for registration). For now this won't be a problem (I will use TCCLE on the Windows 7 installation), but I am going to change the computer name on my home PC (actually, I will give the old one away, probably after formatting), so apparently I'm going to have a problem. How can I check which computers I have used the registration key on? How can I remove one of those to add a new one? According to the license, I can use each "individual copy" up to three computers (home, work and laptop)? Does this still apply?
