W7 backup error code: 0x80070578 invalid window handle - help please

Hi. Have been running Windows back-up successfully for several months, and now an error: 0x80070578 has cropped up - unfortunately, after tracking down that it means 'invalid window handle' (why the xxx doesn't Microsoft tell you instead of just giving an obscure code ? *), I am none the wiser. Is there anything that a mere user (i.e.non-geek) can do to avert this terrible calamity please ?

(yes, I do have another - cloud - backup which seems to be working successfully. And I systematically check for and apply updates; system watched over by ESET antivirus, IOBIt pro and malwarebytes. No recent changes, except for installing AntiLogger free. No, I am not happy with the way Window works, but that is Microsoft's fault, not mine).

Thanks, old gobbo

I cannot answer your question because I've had my own issues with Windows Backup and discarded it completely. It seems to work for a while and then stops without a good explanation.

What I would suggest is what many of the regulars here do: use an alternative freeware such as Macrium Reflect Free (see Backups in our Freeware DB)
