How to transfer Windows 10 to new computer with everything untouched

Transferring Windows 10 from an old computer to a new one can seem straightforward with the built-in backup and restore feature, but there are some disadvantages and potential hiccups you might want to consider before diving in. 

Disadvantages:

1. Hardware Compatibility Issues: One of the biggest challenges is that the new computer's hardware might not play nicely with the old system image. Drivers for your old machine could be completely wrong for your new one. You might end up dealing with crashes or performance issues until you can sort it out.

2. Activation Problems: Although you should be able to enter the old product key once you've set up the new machine, sometimes Windows can be a bit stubborn about activation. If your new PC has a different hardware configuration (especially the motherboard), you might need to contact Microsoft support to activate Windows.

3. Software Conflicts: Programs that worked perfectly on your old computer might not function correctly on the new one, especially if they rely on outdated drivers or specific hardware configurations. You might spend time troubleshooting compatibility issues, or worse, find that you need to reinstall many of your applications.

4. Time and Patience Required: The whole process could take longer than expected, especially if you're dealing with a lot of data or if you're doing some troubleshooting along the way. Plus, you'll need to back up and restore files, which can sometimes feel like a chore.

5. Personalization Loss: Transferring Windows 10 to new computer means you get everything as-is from the old PC, but that also includes settings and personalizations you might want to change on your new device. With a fresh start, you could clean up what you don’t need any more.
