According to Microsoft's description, a Windows repair installation involves replacing the currently installed version of Windows with a completely new installation of the operating system. I therefore assume that there are no significant differences compared to a clean installation of the operating system, which also overwrites all other programs and data. Of course, I can't completely rule out the possibility that this might resolve a hidden error that has been preventing the installation of Windows 24H2.
I can understand that Bill K is reluctant to go through the hassle of completely reinstalling the operating system and all the applications he installed. It takes me at least a whole day to get everything back to the way it was before. I only do it when all other solutions have failed.
oldscholl is right, staying with Windows 23H2 is not a long-term solution.
