OK - haven't heard of Macrium Reflect before and will look into it...
Macrium Reflect [free edition] is often recommended in this forum for making system images. Other utilities are available but this one is so commonplace that you can get plenty of help for it.

It can also make bootable system images. This facility is called viBoot and it requires Win10 Pro.

While you're thinking about backups, consider Backup and Restore Device Drivers - TenForumsTutorials as well.


Don't be tempted into using Windows imaging.

MS said not to in their announcement of Windows 10 Version 1709 and have never withdrawn that warning

imaging deprecated in Ver 1709 - TenForums
