I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101 after rebooting.

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.

Windows for home | Windows 11 | Windows update

Dear Ramesh,

Thank you for your assistance, you were really helpful.

At a point my pc touch screen stopped responding during the many installation attempts, so didn't know what I had done to cause this. then I decided to clean install, so i chose not to keep my files and settings and it worked.

    I agree, I just had to reinstall everything, including a damaged SSD internal drive due to excess of shutdowns. Now I installed from a 24H2 "create media tool" a a new update is giving me again the same issue. Tired of Microsoft.

    Having been a windows for c. 30 yrs, I now feel Microsoft has lost the plot - I don't want to ditch printers, sounds cards, backup software simply because MS doesn't want old drivers - and if this happens again I will buy an Apple Mac (which it probably will when 25H2 arrives).

    Long story short, because my up to date Acronis software rendered my C drive unbootable (thanks), I used a standard Win PE recovery key (sadly I had not updated it to Win 11 so it installed a bare bones/clean Win 10). Thereafter it upgraded automatically to 22H2 but stopped there (bear in mind I was on 23H2 before).

    I then installed 24H2 from an iso download - but having then installed Acronis backup/recovery software (up to date) and with considerable difficulty Creative X-Fi SBX drivers and Canon printer drivers for a 10 year old printer I now find Win 24H2 advising memory integrity issues because of five incompatible drivers (4 of which are Logitech - presumably mouse - drivers and one Acronis driver tinmntr -- annoying because I have no Logitech stuff whatsoever and given #5 driver problem is specifically Acronis I assume the four problem Logitech drivers are also from the latest Acronis True Image installation for their version of the Win PE recovery package).

    Where next, I don't know. But I am not convinced that these driver issues are unlikely to compromise Windows to the extent Microsoft fear but in the meantime I am running Win24H2 with memory integrity and local security authority protection off.

    Any comments?
