Windows 10: How does restore to dissimilar hardware work?

Say i have intel cpu and a nvidia gpu now which i do, And i want to replace everything Motherboard,CPU to AMD one, new RAM, and a AMD GPU. and i got a backup software which supports restore to dissimilar hardware.

my question is this what happens? whats the process like?

How to transfer ssd to new computer with windows 10 without formating?

You need to make a backup of SSD with a backup and restore software which supports restoring to a dissimilar hardware. One good solution is AOMEI Backupper with dissimilar hardware restore feature (Universal Restore).

 

Restore files from backup from previous (crashed) computer to new computer

Windows built-in Backup and Restore does not have the function to restore to a dissimilar hardware. You have to use a third party software with

Universal Restore feature.

 

Hello unfortunately you haven't stated which imaging software you are using.

This outlines what happens when you use Macrium's Redeploy; Macrium Reflect is one which many contributors here use and recommend.

Here's Aomei Backupper:

I got Aomei Pro the link you provided made it sound easy, i thought it would be a lot more complicated then that.

 

Ok, let us know how it goes.

 

They basically automatically update the drivers for the new device but without going through the oobe phase if you used sysprep to remove hardware drivers.

 

I'm not sure if this still works, maybe @Kari will show up and give advice, but this is how you could do it on Windows 7 with an existing system: Windows 7 Installation - Transfer to a New Computer - Windows 7 Help Forums
It also explains what happens.

 

That method is based on generalizing Windows with Sysprep, making it hardware independent. Sadly, that does no longer work as told in that tutorial in Windows 10. You can still use Sysprep to generalize a cleanly installed Windows 10 image before any users and software have been added, but you can't do it on existing Windows 10 installation.

That's why that tutorial never was ported to Ten Forums.

 

Sysprep doesn't work if store apps have been updated.

 

Sysprep works perfectly on an existing Windows 10 installation, it's just that you can't use the /generalize switch when apps have been provisioned.

 

Redeploy is not quite the same as sysprep.

In sysprep with generalisation, hardware drivers are removed, and when reinstalled on another device, Windows reinstalls appropriate drivers on first install.

Redeploy updates drivers using the Redeployment Software, essentialness discarding those it does not need i.e. in effect doing the driver removal and addition as one step rather than two discrete steps as sysprepping/oobe does (i.e. removing all drivers first on old PC, then installing them on new PC).
.

Actually, Windows 10 driver handling is so good compared with previous versions, it pretty much works like redeploy automatically anyway.

If you install Windows 10 in a VM, and make an image backup, and restore image to host, it just updates all the drivers automatically in most cases even if never installed on host before.

Of course, if you do not have Redeploy capability, the cleanest solution is via sysprepping but that has its own Windows 10 issues as @Kari says. The slightly dirty solution is to use Windows 10 own driver handling ability.

For a one change of hardware, it is barely necessary to sysprep any more, and even if any issues arise, most can be resolved from device manager.

However if redeploying across multiple devices, sysprep is the way to go (if you do not have Redeploy capability) and it is free as well of course.

 

Something I thought of, but don't know if it's required:

Is the OP using a retail key(required)
Does the OP need to deactivate the key first using slmgr /upk before he moves his system, then reuse it?

 

If solely a digital licence e.g. an upgrade from 7/8 in which case no.

If key was a retail standalone key, then generally you can reactivate licence on new PC several times before it complains, and then you might need telephone activation, so no really.

 

Ok. Better to ask and learn, than die stupid(something they say in Germany, but sounds better in German too)
