How to Get Moving Wallpaper on Windows 10

If you recently built or bought a new PC, you may be wondering if you can just transfer your old hard drive into the new computer–thus migrating your entire installation in one fell swoop. But it's not as easy as it seems.

Linux systems generally load all their drivers at boot time, which mean they're much more portable–that's why Linux can be loaded from those convenient live USB drives and discs. Windows systems don't work like this, though. When you install Windows, it becomes tied to the hardware on that PC, and if you put it into a new PC, you'll encounter a few problems.

The Technical Problem: Device Drivers

If you actually try moving a Windows drive to another computer and booting from it–or restoring a Windows system image backup on different hardware–it usually won't boot properly. You may see an error about problems with the "hardware abstraction layer" or "hal.dll", or it may even blue-screen during the boot process.

That's because when you install Windows on a computer, it sets itself up with drivers specific to that computer's motherboard and chipset. The drivers for the storage controller, which allows the motherboard to communicate with the hard disk, are particularly important. When Windows boots on different hardware, it doesn't know how to handle that hardware and won't boot properly.

The Licensing Problem: Windows Activation

RELATED: How Does Windows Activation Work?

Windows activation is another hurdle in the process. Most people get Windows preinstalled on computers they purchase. These preinstalled versions of Windows are OEM ("original equipment manufacturer") copies, and are designed to be locked to the hardware they were originally installed on. Microsoft doesn't want you to be able to move those OEM copies of Windows to another computer.

If you purchase a retail copy of Windows and install it yourself, things aren't so bad. The Windows activation process is designed to make sure you only install that copy of Windows on one PC at a time, so changing a computer's motherboard–or even some other bits of internal hardware–will result in the Windows system becoming deactivated. Thankfully, you can just re-enter your activation key.

The Result: Moving a Windows Installation Is Complicated

All that said, moving a Windows installation to another computer is possible…in some cases. it requires a bit more tweaking, isn't guaranteed to work, and generally isn't supported by Microsoft.

Microsoft makes a "System Preparation," or "sysprep," tool for this very purpose. It's designed for large organizations and PC manufacturers, giving them a way to create a Windows image and then duplicate, or deploy, it on a variety of different PCs. An organization might use this method to deploy a Windows image with various settings and software installed on all its PCs, or a computer manufacturer might use this trick to install its customized version of Windows on its computers before selling them. It isn't designed for average Windows users or enthusiasts, though, and it won't run at all on an upgraded copy of Windows–only one that was clean installed. As Microsoft's support page puts it:

"If you intend to transfer a Windows image to a different computer, you must run sysprep /generalize, even if the computer has the same hardware configuration. The sysprep /generalize command removes unique information from your Windows installation, which enables you to reuse that image on different computers. The next time you boot the Windows image, the specialize configuration pass runs… Any method of moving a Windows image to a new computer, either through imaging, hard disk duplication, or other method, must be prepared with the sysprep /generalize command. Moving or copying a Windows image to a different computer without running sysprep /generalize is not supported."

Some enthusiasts have tried using "sysprep /generalize" on a Windows installation before attempting to move it to a new PC. It can work, but since Microsoft doesn't support this, there are many things things could go wrong if you try to do this at home. Nothing is guaranteed.

Other disk imaging tools have attempted to serve this purpose, too. For example, Acronis offers a tool called Acronis Universal Restore designed to be used with the Acronis True Image disk-imaging software. Essentially, it replaces the hardware abstraction layer (HAL) and hard disk controller drivers in an existing Windows installation.

This will de-activate Windows, and you'll have to go through the Windows activation process again after doing so. If you have a retail copy (or "full version") of Windows, you'll only need to re-input your activation key. if you purchased your own OEM (or "system builder") copy of Windows, though, the license technically doesn't allow you to move it to a new PC. However, you may be able to re-activate it using Microsoft's "Phone Activation", designed for those without internet access. Give it a try and see if it works for you. If that OEM copy of Windows came preinstalled on a computer, Microsoft definitely won't let you re-activate it.

You Should Probably Do a Clean Install Instead

You could try messing around with sysprep, Acronis Universal Restore, or another method that will allow your Windows installation to boot on another computer. But, realistically, you're better off not bothering–it'll probably be more time and effort than it's worth. If you're moving to another computer, you should usually just reinstall Windows or use the new Windows installation that comes with the computer. Reinstall your important programs and migrate your files over from the old computer rather than trying to migrate its entire Windows system.

If you need recover files from a dead computer's hard drive, you don't have to boot into its Windows installation. You can insert that hard disk into another computer and access the files from your new Windows installation.

If the exact configuration of that Windows system is so important to you, you might want to consider converting the Windows installation on that computer to a virtual machine image, allowing you to boot that image in a virtual machine on other computers.

Windows really isn't designed to be moved between hardware without a full reinstall, and that's why it's best to create backups of your files with something like File History or another file-backup tool rather than creating system image backups. Those system image backups are really only good on the PC they were originally created on. You can extract individual files from a system image backup, but it's not quite as easy.
