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.

    Now my PC is trying to download 10.0.22000.100 (co_release) and failing right away reporting no TPM 2.0 chip. Again, I thought those of us already in the Insider program were supposed to be exempt from that requirement (with the understanding we'd need to clean install Win10 once the preview was over). I give up.

    First off I hear that windows 11 advanced release is rather nice.

    Having said that, it appears that the advanced release is geared towards machines that have virtually no applications or drivers or peripheral devices. That seems a bit presumptuous given people who participate in the windows insider program don’t tend to have naked machines.

    If I were you I would give up on the entire windows 11 advanced release until Microsoft’s installation program has more brains than a box of rocks.

    Well I went back and tried my upgrade once more before I started to remove my second SSD drive and try other things, and on the second try, it installed completely. I think I had just one other update that I let Microsoft update me to before I started the install procedure, so I'm ok with the upgrade, hope you find out what your issue is. And no I don't have any capture cards, I do have one that's USB, kinda older type but still in it's packaging.

    My system to say the least isn't your average run-of-the-mill setup either I have dual ssd's with a different copy of WIndows 10 on each, my main drive is pro, and the second is home, then I have a 2TB standalone drive, then I have 4 1tb drive setup as a raid 5 configuration, running an 8700K overclocked most the time, so I assumed if anyone is going to run into any issues it would probably be me. But I was surprised that I did not have any. Not to mention my TPM isn't a real TPM it's just firmware running through a setting in my BIOS. SO go figure.

    I've solved it! I have two SSDs on my PC, and I remove the after one（Toshiba 512G）, and it works! If you have two SSDs too you can try it

    Hmmm, I have two SSD's in my system also...I'll give that a try and see what happens.
