I didn't look up the errors but how people get themselves into trouble is they seek out the vers 2004 update on their own and install it. Did you do that? If Windows update did not offer it to you then there was a compatibility problem. If you sought out the update and did it on your own you might have to try to roll back to 1909 and if that fails....uh oh..maybe a wipe/reinstall is easier than chasing down weird errors. You should definitely not be seeing errors.
I waited a super long time before doing 2004. Windows never popped a notice it was ready but when I typed "Check for Updates" it was there under downloads and ready to install, so I took a chance that it knew I was going to be OK. So far, so good. =)
