Windows 7: Running Excel with specific processor affinities

Running Excel with specific processor affinities

Hey all,

I am looking for a way to run excel with a permanent processor affinity in windows 7. I've found a few options, such as a temporary registry hack (would've worked if it was permanent), a power shell command (which would work if there was a way to make windows run the script every time excel was opened), and a batch file shortcut. None of these things quite address the my problem.

No matter how excel is opened (a.k.a. whichever shortcut, file, or script is used to open it), I want the processor affinities automatically assigned without user input. Back in XP the registry hacks were permanent, so those were pretty awesome, but I don't know how to rig something like that up in 7. Any advice you guys could provide would be appreciated.

Hello Ashi, :)

You should be able to use the method in the tutorial below to create an Excel shortcut that will open and run with the set CPU affinity.

Yup, which is a useful work-around, but I'm hoping for a permanent fix. I have several hundred excel documents I need at random, and I don't feel like spending the absurd amount of time needed to make a shortcut for each and every excel file I have on my computer (not to mention, modern versions of excel have an abysmal UI, so trying an in-program open takes even more time than making the short-cuts would).
