Hi, I've had my custom build computer for around 6-8 months now and is becoming slower than when purchased i would like to make a fresh re-install and know how to do this furthermore i have used up all my windows 7 keys(4) i don't particularly want to speak to Microsoft and at the moment i have an 'OEM' key is there any way of me deactivating this key then reactivating after the install?
thanks in advanced oli
