Windows 11 Update Failed, then Windows Update failed

I was just offered the opportunity to upgrade to Windows 11 in the Release Preview Channel. I gladly accepted the offer. The upgrade downloaded, then installed (seemingly 100%), and then rebooted. Wi...

    It seems that on many computers there is this problem!

Thought that might do it. After decrypting, the machine updated without a hitch and again offered me a chance to upgrade to Windows 11. Again I accepted. It showed installation 100%, then scheduled my restart (I restated it immediately), and when it came back up it said it was getting Windows ready. Hmm, could that mean it was getting Windows 11 ready for me? Unfortunately, NO. Same OS is installed (Windows 10 Pro). No error codes - it's as if nothing happened at all. Now all my Windows 10 updates are installed (at least that problem is resolved), and I have the original "Upgrade to Windows 11 is ready - and it's free" offer in Windows Update. Should I try it again for the 6th time? I guess I will, but I don't have much hope that it will install.

after you install it and it downloads and reboots, it comes up as windows 10, then you should go to settings and update and select check for update, then a windows 11 build will download from the updates and install as normal. Also check to make sure that your dev tools are turned on. To do this go to settings and then find the allow remote connection from computers on my network and the allow usb connections option. Toggle those on and you should get a message stating windows is downloading additional tools.

If you have a windows insider account you can go to the insider ISO download page and do it that way

    Well, got the additional tools, as you suggested, by turning on developer mode, and turning on the USB switch. Tried installing the upgrade again but no luck. I'll try using the ISO next time.

      I wonder if in your situation after so many attempts it may be worth waiting for a stable
      Windows11 version.
      And these are the currently available ISO versions
      The safest form of updating, however, is Update Windows - it provides a trouble-free return to the previous version of the system and does not expose you to failure.
      please think about it.

        I have been offered this by Windows Update. I thought that as a participant in the Release Preview Channel I would only be offered stable Windows 11 versions.

    I have tried back-to-back installs of the Windows 11 upgrade (Upgrade indicates it is being installed and getting Windows ready, but no change is actually occurring) several times. I did't have developer mode turned on - just did that and toggled the USB switch as you suggested, and am trying to upgrade again now. Will let everyone know how it goes. BTW, every time it has to re-download the upgrade. Wouldn't it save time if the download was done just the first time (not every time)?

      I believe I understand you correctly but just so I understand you have gone to the insiders tab downloaded it, rebooted, then gone to the windows update , run the update check , and windows will download a windows 11 update ...

      https://docs.microsoft.com/en-us/windows-insider/ISOs select download ISO, enter credintials for insider downlaod the Win 11 home ISO, once downloaded open the ISO and at the bottom should be a setup.exe file to run

        _RBL_ I have selected the Release Preview Channel. I downloaded the ISO (Windows10_InsiderPreview_Client_x64_en-us__19044.iso), but when clicking on it I receive the following message:

         

        If I try to right click on the file then file explorer will restart.  Do I need to go out and buy some writable DVDs?
