Question

Hello.&nbsp;From a long time I tried to upgrade my Windows 11 Build 22.000.co_release.210604-1628 to Windows 11 Insider Preview 22543.1000 (rs_prerelease),but everytime I get the error "Installation error - 0x800700c1" and it won't complete. I'm not so experienced. Do you want to explain how can I fix this error ? thanks.

I am facing that error too. Microsoft's products are too buggy now-a-days. It is very annoying. Overall I am frustrated.

moin1407&nbsp; where have you store those files extracted with WinRAR, which folder?Seem I am missing that repair folder, as it constantly brings only the option to install all new and losing all data.&nbsp;&nbsp;

Der Fehler besteht immer noch. Sowohl über Windowsupdate auf eine neuere Version, noch der Weg über eine aktuelle ISO funktionieren. Treiber sind aktuell.
