Hi
As per heading of question, my laptop is enlisted in Windows Insider Program for Windows 11 Home edition. I had been receiving insider updates and all installed smoothly. Bu the update as per subject line became available 2 days ago and i proceeded with download and install. After 100 % installation, restart prompt flashed. i promptly restarted but for some reason laptop was taking inordinately long time to apply all updates. After 1 or 2 restarts, laptop simply shut down instead of restarting. I started laptop using power button. And now i received message that last update failed and hence reverting to last known configuration. Laptop finally reverted to earlier state. But again update became available as i have enabled auto update. I downloaded and installed update once again. But this time before restarting, i checked all the drivers were upto date, UEFI and other boot options were enabled, and i removed all USB plugged peripherals. BUT when i clicked the restart again after 1 or 2 restart while applying updates, the laptop just shut down. And when i switched it on , again the process of reverting to last working configuration started. My laptop fulfils all requirement for Windows 11. It is Acer Predator G9-791.
I need to know why this update is failing to install and reverting to present configuration. Kindly advise , any and all inputs are welcome
here i am sharing link to feedback hub as suggested - https://aka.ms/AAp1vq4
So guys and gals, here i am posting a way to resolve it. If you are enlisted in Canary or Beta channel, then update is going to fail invariably. But if you are on Dev channel, then there are very good chances of the update going through. But for changing from Canary or Beta to Dev channel, you will have to install Windows Insider build 23165 from https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso?wa=wsignin1.0.
Give it a shot and see whether it resolves it for you as it resolved this update error for me.

Step 1 :: Checking your Device Manager specially Storage Manager below
Delete other vender such as " SAMSUNG NVME Controller " and etc. leaving it to those picture above instead.
Re-Update Windows 11 Insider Preview lastest build for your rigs. Finished.

Hi Ajit Duhoon,
Your CPU is not on the list of approved Windows 11 CPU, but saying that my computer on W10 runs W11 in Hyper-V with a non CPU for W11.
On this page are some common 0xC1900101 but if you know the full error will help you. I know it says W10 but still good for W11.

Have you run DISM and sfc on your system at all?

Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support
I know the Acer Predator G9-791 is getting older but I would still check I have the latest bios installed and also check it's not overheating as dust can build up on the fans, etc.
The last thing I would try is SetupDiag - Windows Deployment | Microsoft Learn but can be quite trying but we will try and help as much as we can.
We are all volunteers here so we are not from Microsoft, and I doubt MS will answer when you have a 0xc1900101 GSOD or BSOD for that matter.
Was there a 5 digit hex number in addition to the original one. One of those may help narrow down the possibilities.
