System backup error [0x80041321]

Thank you so much!  I was having the same problem - went from 7 to 10 and back.  This worked for me - thankfully.  

I am finding all sorts of problems after reverting back.  As far as I'm concerned Windows 10 is a total disaster for MS.  While I've been searching for solutions to the numerous problems I'm now experiencing it seems like most people are having the same problems and MS is doing nothing about it.  Total BS.   Still can't get my firewall to work so I guess I'm going to have to buy one which MS should have to pay for.

Very Good. Pay heed when everybody says to back up your files when updating in Windows. I updated Windows 7  to Windows 10 and paid the price of losing all of my files. I lost all of my saved files along with years of favorites. I updated to Windows 10 and went back to Windows 7 and had the same problem with the back up issue of the error message however your method worked to get the back up working again. I had no luck of retrieving my lost files after reverting back to Windows7. Back it all up before you push the button. Windows has a lot of issues to be dealt with. Thanks for your advice with the  back up problem, worked great.

Thank you my dear. Your suggested steps 1-4 above worked like a steam engine (not quite so polluting I dare say!)

Have a Good Christmas and a happy, healthy and prosperous New Year!

YES! You are absolutely right rpthorn. Big corporation punishing little people like you and me for not liking their latest IDIOCY they called windows 10. They haven't learned the lesson from last century!

And this is the reason: Not enough competition to teach MS a lesson they never forget! and all about capitalism being an economic system of fairness is a load of BS!

Thanks.

Great helps for me!
