KB5101650 breaks Microsoft Store app update toggle (even for admins)

Hello,

I had the same issue for weeks through multiple clean re-installs on Windows 11 Pro 25H2: Microsoft Store showed “You need administrator privileges to pause updates”, even though my Microsoft account is an administrator.

I eventually just found a workaround that fixed the Store pause function for me:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\InstallService → Permissions → Users → enable “Full Control”

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\InstallService\State → Permissions → Users → enable “Full Control”

After changing those permissions in regedit with my user account, I could immediately pause Microsoft Store updates without any error.

In my case this has been reproducible after clean Windows installations, so I currently consider it a workaround rather than a permanent root-cause fix. It fixes the Store update-pause permission problem, but it does not resolve the other Store / InstallService / LiveID errors I have been seeing.

I documented the original issue, reproduction steps and additional Store-SDK / InstallService / LiveID logs here:

Microsoft Q&A: “Microsoft Store: ‘You need administrator privileges to pause updates’ on Windows 11 Pro 25H2”

If you have the same error, it may be worth checking the permissions on those two InstallService registry keys and comparing your Store / InstallService logs with the ones in that thread. Please note that its a bug and issue that affects many users but Microsoft devs do not have recognized yet.
