Not long after loading all my software onto a new PC with an OEM copy of Windows 7 the PSU blew causing catastrophic damage to the motherboard. The store is to replace the machine with an identical model. Luckily I've got a complete backup courtesy of Paragon Hard Disk Manager 2011. However I'm wondering if I'll be able to use it on the new PC which will have a different Windows 7 OEM product key. Am I likely to have problems with licensing etc?
