Before install June cumulative update Windows Admin Center works fine and no error happened.
I was told by a Microsoft assistant to come here for help regarding an insider update issue.
As the title reads, a Microsoft assistant told me to consult this community regarding the issue I am facing now. A while ago, I foolishly did not read the fine print and opted into the dev channel of the insider program, because I was having difficulty installing Windows 11. I later found out to my horror that, I could not opt out until a particular window was announced. I have been waiting since then, and updating my computer in hopes that one of these updates will allow me to swap back to the beta channel, and then, hopefully to a stable version of Windows. When I attempted to update today to the "Cumulative Update for Windows 11 Insider Preview (10.0.26120.2705) (KB5050636)", I received the "Install error - 0x800f081f" message, and all the results I have searched have so far given me nothing but pieces of advice that make me fearful for the safety of my computer data. Is there anything I can do that will not run the risk of data deletion, or is it hopeless? I feel like I've run down every alley here. Thank you.
