Backup error: The task image is corrupt or has been tampered with

I am doing my first backup in a while. I don't know if it is related, but since my last backup I have switched to Windows 10 and back to Windows 7. Using Windows 7, I get the error "Backup error: The task image is corrupt or has been tampered with x80041321." I am unable to proceed.

Please note I can follow explicit detailed instructions but I cannot follow instructions written for people really good on computers that leave steps out or assume you know them.

I have Googled this error and have not found anything very recent. I think it is best for me to start here. This forum has always been very helpful to me. Thanks.

Note: I posted this originally under Backup and Restore and have gotten no response.

Install and use Macrium Reflect Free to create your image backups.

Good tutorial for it here: Imaging with free Macrium

The tutorial link did not work. I am really looking for a solution on how to fix the Windows backup error.

The links you sent me did not help.

Since I have tried all kinds of solutions that I have found on the internet, long confusing suggestions, I cannot fix my backup. I looked at the macrium as you suggested but under the free version there is not a check by the "File & folder backup" option. That makes me think I can't back up my stuff. I am so confused, not getting any help and don't know what to do. I have found a few other postings of people having this same problem after reverting back from windows 10 but not solutions.
