From GitHub, use bat file to in place upgrade Windows 11 v24H2

I Regret.
In place upgrade , after 100% installation, displayed green screen.
Undoing changes put my pc back to build 26080.
See the error message in image attached herewith, please.
Now clean install of build 26085 canary channel from usb is going on ...55% complete... Restarted pc 92% complete... just a moment...
Installed successfully. Please see the images.
In post #10 in this thread on page 1, please read as
x:\sources>K:
K:\> cd sources
k:\sources>
instead of x:\sources>cd K:\sources
Thanks.

This might have its uses but I'm not a fan of 3rd party stuff fiddling around with the registry.If you want a choice of editions to install simply from the UUPDUMP site create an ISO with the relevant editions you want. Then either install (update existing edition), install from scratch (then you will get a choce of which edition to install) or use the dism /Apply-Image method selecting the install.wim for the build you want.

@Bree

That script looks fine but:

Getting a decent iso from time to time is useful for those using VM's or wanting to create "Windows to Go" type of systems. I have several builds on a 2TB external NVME (SSD type) M2 device connected to the host via USB-C connector. The response time of the various Windows builds is still pretty good. I have those windows builds in different languages and some different applications -- IMO much better than endlessly re-booting your main Windows machine if you want to change language or run different apps.
