I would like Parallels to use my Boot Camp partition with XP on it, which it can, which is great. However, my Boot Camp installation is an OEM version so when I boot the VM up I am asked to reactivate, however I cannot do so because my key is OEM. Fair enough. I have a second OEM XP key at my disposal, so I would like to know if it is possible to either a) use a single OEM key without reactivating every reboot, or b) Utilise the second key in Parallels and have it and the activation information switched around automatically. Any help would be appreciated.
