Default Prime95 doesn't start automatically even with "Start at Logon" enabled

On one of my PCs, Prime95 does not start automatically even though the "Start at Logon" option is checked. Disabling and re-enabling the option does not help. As far as I'm aware, this does not happen on other computers. Anyone have an idea what might be the cause?

It's not a huge deal, but does get annoying when the computer is restarted for whatever reason.

There is a tool by Microsoft's Sysinternals: Autoruns. Does it show up there?

Prime95 uses the registry to "Start at logon". It will use the "Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" location to store a "Prime95" entry with the path to the executable to ensure the program is run at logon.

For instance if Prime95 is running from the C:\MyPrograms\Prime95 folder the "Prime95" entry would have the value :
"C:\MyPrograms\Prime95\prime95.exe"

But these keys are ignored when the computer is started in Safe Mode (unless one prefixes the string with an asterisk "*" but that might only apply to the "runonce" keys.)

Another thing : the run keys can only store commands that are less than 280 characters.

You don't need the registry to verify if a program is set to start at logon : use Task Manager; if needed click on "More Details" and check the "Startup" tab. If Prime95 is set to start at logon you should have one "PRIME95 Application" line.

If everything seems correctly set and the program still doesn't run at logon, you might expect to find the reason in one of the hundreds of event logs, but AFAIK there will be nothing : the logon process doesn't log that kind of events.

Another way to ensure a program starts at logon is to use the TaskScheduler which will result in logs or the startup folder : C:\Users\User\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup ...

Another idea (far fetched) is maybe you clicked on "don't show the icon" and it is in fact starting, but it is hidden. This would be easy to see, if you look at CPU occupancy after about 30 seconds from start, or longer, you should see your cores busy (half of them if CPU has HT and it is disabled in P95).

Thanks for the ideas. I'll check the registry entries.

I don't believe this is the case because there is no active Prime95 process.
