done and checked as instructed, reagentc working as explained, disk 0 /part.4 recovery is over 550MB of which 90MB free... still error 0x80070643 came up on win update yesterday without mention of WHICH (KB) update:
"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)"
..but update history unveils:
KB5001716 Update for Windows Update Service Components.
Failed to install on 06.03.2024 - 0x80070643
hope there is a solution soon, as update Service appears to be an important part of Win10 working hassle free and specially secure from hacking, this as I got a view intrusion attempts into MS-account from Ukraine !!! and China!!!
