P.S. In my quest for future-proofing things, I noticed I have been able to load VRD without the validation step, on an identical machine ( a corporate HP Compaq Elite 8300). The Windows 7/Videoredo installation was backed up/restored onto secondary machine using Clonezilla. Secondary machine had EXACTLY the same hardware configuration, except of course for the different system board and CPU (It didn't care about different BIOS revision or the i5 CPU changing to i3 CPU though). No WiFi or other additional devices to complicate things at the time of running Clonezilla. I pulled up the wizard in Windows 7 to activate on the secondary machine. Then I went into VRD and the About screen, and my license was still good.
So in short, if you can backup/restore using a drive image to a nearly identical machine, you may be able to circumvent the requirement to reinstall VRD a second time.
Caveat: For unknown reasons, there was an additional requirement to install "Windows6.1-KB3102810-x64.msu" patch, which fixed the Windows Update services in Windows 7 - which can be broken on new installs - or in my case a drive imaging to another similar machine. That is temporarily required for the Activation step in Windows. Once activated, I'd recommend disabling that Windows Update service altogether.
Since I have a few of these machines, I have made a hardware-redundant setup on each machine, each backed up on several HDD volumes using Clonezilla. That is in case the validation server should go down, and the drive imaging loophole above doesn't work again.
