Update screw-up again

Why is it nearly every time an update has been due this year, after trying to download and install them there is always an error?

Once again I had to redo the latest set of updates, as first time round errors were shown. Once finally installed without an error message, I ran sfc /scannow, only to find that errors/violation of the system had taken place. I think this issue has now happened 3-4 times in succession now.

Why does this keep occurring?

Thnx for response. I have error id no.20, - 0x8024001E and 0x800F080A, both of which refer to the cumulative .NET Framework update. It failed twice to install yesterday, but succeeded on my 3rd attempt.

Nothing wrong with the disk showing on Crystaldiskinfo - 100%. It's a fairly new disk anyway.
Result of chkdsk c: /SCAN:
Windows has scanned the file system and found no problems. No further action is required

The update is started as it always has been. Go to the Settings-->Update/Security page and and click Download. It's the Cumulative updates that seem to cause an issue. MRT update always goes through just fine, although sometimes the Security Intelligence Agent for Defender updates also fail on first attempt.

That update also gave me problems i had to update it twice, it crashed my explorere on login and then reverted a restore point after the first time. Just keep trying worked the second time after that.

Yes it was the recent net frame work update

Yes, that's another issue (BiB). I always make a restore point before an update. But each time I make one it often gets deleted after the update has taken place. That's been an ongoing nuisance for years with Win 10, and never fixed.
