In Win 8 you can search for "recovery" and find the system image backup
tool. In Win 8.1 they changed that, you have to go to the "File History" in
the control panel and at the bottom left is a link to "system image backup".
I use AOMEI Backupper which is similar to macrium reflect only the free
version of AOMEI allows for full, incremental, and differential backups as
well as schedule backups. I have done a image/restore operation on an old
laptop to test it and it works perfectly. Microsoft seems to love moving
stuff around and renaming functions from version to version. Back in the day
I used to use Norton Ghost but AOMEI does everything I need and its free.
Win 8 and 8.1 also has "refresh" and "reset" tools. I still prefer to use I
have used these tools on a few relatives computers who didn't have proper
backups and they did work. Hope this helps.
