This is the method to stop the 24H2 update and other updates will install normally:
Click your Start Button, then just type cmd and from the resulting list, right click Command Prompt and choose 'Run as Administrator'
Paste this command into Command Prompt and press Enter:
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate /v TargetReleaseversion /t REG_DWORD /d 1
Paste this command into Command Prompt and press Enter::
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate /v TargetReleaseversionInfo /t REG_SZ /d 23H2
Close Command Prompt
Open File Explorer, then navigate to C:\Windows\SoftwareDistribution\Download
Delete the contents of that folder, not the folder itself and restart (not shut down) your PC.

Then, at a later date, if you want to install the 24H2 update, you would need to open the Registry Editor, then go to this location:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
And delete the TargetReleaseversion entry.
