XP Pro x64: Program started at boot with automatic logon behave differently after update

Question

I have a program that I wrote in .NET to select games for mame (arcade emulator). This is a frontend. I configured in the registry an automatic logon for the administrator. In the "startup" windows folder, I added a shortcut to my program.

My program then launch at boot time and I can select a game from the menu. The program then spawns a process to execute "mame.exe" with the game I chose. Everything worked fine for several months.

I updated my Windows XP Pro x64 the other day and since then, when I choose a game, the process "mame.exe" is spawned but its frozen (I have to do end task on the spawned mame.exe, the game never starts).

It does it only when I try it immediately after the automatic logon (when the frontend was started by the "startup" folder at boot time) When I start my frontend manually after a boot, everything works fine. I'm suspecting credentials issue when the frontend is started by the system at boot?

There's so many patch installed that I don't know which one to uninstall to return to my previous state.

Any ideas?

Thanks

You can check when they got installed. Delete just the ones which came recently or mentions this. You should also have a System Restore point to roll back.
