1) You may need to adjust the restored image to boot on different harware.
For windows 7 Make Windows 7 bootable after motherboard swap - Windows 7 Help Forums
Probably not needed for win10.
2) You will need a license for the OS on the new hardware.
Try it and find out.
You are supposed to be able to do so using the paid version of Macrium Reflect using Redeploy. See http://knowledgebase.macrium.com/di...indows+to+new+hardware+using+Macrium+ReDeploy
If using redeploy on the paid version of Macrium Reflect, do not enter the license code on the original installation of Win 7 until after you have made an image of the installation. Then, just enter the individual license codes after "restoring" to the subsequent PCs.
Windows installations are ties to the MOBO serial number so you either have to use a new license on each new installation or, deactivate the license on the old PC then reactivate it on the new PC (assuming the license is retail). If you only have an OEM license and you are moving from a dead PC to a new one or a dead MOBO to a new MOBO on the same PC, you will need to call MS and beg, grovel, whatever to allow the transfer (you may need to call more than once to get a sympathetic operator).
You could try OODiskImage, it has few functions under Tools>Change Computer Properties. You can point it at a resored image, before booting into the restored version.

Reading that page, seems to me that in my case it was probably a OEM:NONSLP, or OEM:COA since the COA stickers attached to the machines were Vista licenses, as confirmed by talking to a MS agent. The win 7 OS was acquired later, possibly oem, possibly retail. Since I'm an individual, not working for a corporation, I can't consult a lawyer before moving a disk from one computer to another. (...and not dozens of computers.) If MS's own license validation does not complain, I assume they do not object.It probably is illegal unless you can get an MS phone representative to agree to it.
The licensing is described here and you appear to be using the OEM:SLP which uses a license embedded in the BIOS SLIC table.
