Sure. 😉

I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101.
The installation starts, and after a couple restarts, it says:
" Attempting to recover installation "
" Undoing changes made to your computer "
And then I am greeted with error 0xc1900101 on Windows Update.

2021-07-31T02:08:02+00:00 I didn't know what you were talking about anyway.
What frustrates me is that I have been getting notifications since May that my 1909 version of Windows 10 has expired and is no longer supported. As if I got any support from Microsoft on Windows before that point in time. They only have a telephone for business clients, not those of us who use their "technology" for home/personal.
I have tried a few suggested fixes, run the Troubleshooter many times (BTW, it continues to say, Last Time Checked: Never).
I use the Windows Update tool and actually get through the entire download. Then I check my version in About and it still says 1909.
But each time I review the Download History under Settings, it shows a new and different error code. Never the same one twice.
Super ridiculous.
Meanwhile Microsoft continues to ask if I'd like to buy some more software.
Right.

A colleague pointed me to tpm.msc and on my NUC, it was showing NO TPM. So I checked the BIOS ... and the Intel Platform Trust Technology was disabled, so I turned it back on.
Boom, tpm.msc shows I have a TPM 2.0 chip on my 2015 NUC after all!
So I'm trying the 10.0.22000.100 preview install again from Windows Updates. Bet it works this time.

2021-07-30T14:10:58+00:00 I completely agree. Without any level of details, we high-end users are left clueless. I do not like to be forced to be clueless.
It is like my car having one dashboard light. Am I low on fuel or oil or antifreeze? Is there a failure with the ABS or spark plugs or emissions? I do not want to rip my car apart to find out what is wrong. I do not want to service everything to fix one problem. SAME HERE WITH MICROSOFT. Just give me something more than a code that states I GIVE UP AND YOU ARE ON YOUR OWN - BUT HAVE A NICE DAY.
