Hi guys! I tried to update to update to the newest build several times. The last time it failed with an error code 0xc1900101 (shown in the Update center). First I tried to update on a laptop which is now in repairs with an utility from Microsoft site as the update didn't appear in the Update center. Then I moved the SSD from that laptop to another one (before giving it to a repair center) as that PC needed to be repaired at that time, just to have my OS during repairs of that laptop. Then, after some time, I tried to perform it exactly like the last time, hoping that it would be done well on the other device, but still got the same error. Since a week had passed, it showed up in the Update center. I hopefully tried to do it from there, thinking that it might really install normally as it's officially available. Still no luck. I did a SFC scan, reported no errors. I did Dism /online /cleanup-image /scanhealth, reported no problems as well. Here are all the necessary logs from the folder C:\$WINDOWS.~BT\Sources in a single archive - Update Logs.zip on Google Drive. Can anybody here solve my problem, please? All the previous upgrades were done well, I've been having this version 1909 since the end of the last year. In general, I've been having this copy of OS since 2017. I did SetupDiag.exe, and with the produced log (also presented in that archive) I can see that the problem is in plugin SxsMigPlugin.dll and there is its own error code, but I don't know what to do with this. Googling didn't bring me to any appropriate results.
