Vista/Windows 7
* When run on Vista/Win7 you will need to run the program as administrator  to see & set  most running files.
* As administrator  with UAC enabled you will get a UAC prompt when launching the program and UAC will also block the Start with Windows option!
* Also, the drive/folder the program runs in must allow folders & files to be created/written to.
Make Vista launch UAC restricted programs at startup with Task Scheduler
Run UAC restricted programs without the UAC prompt

 Special Notes & User Feed Back:

Thanks to everyone who has sent us feedback!

Just wanted to let you know of a handy way to work around the UAC prompting for starting PriFinitty and others with Windows. You can create a scheduled task to run at logon with “highest privileges” thus bypassing the prompt. Method found here: Make Vista launch UAC restricted programs at startup with Task Scheduler

Thanks for the feedback!
I had the "CPU Usage Query Failed" error on Windows 7 64bit.
Opening CMD.EXE and executing lodctr /R did it, now
setaffinity64 runs again.
Kind regards, Baltzer

Thanks for the feedback!

I tried Affinity 64 (beta 1.0) program it's working very well, and what is interesting the icons for the 64 bit  programs reminds me to AtariST icons in monochromatic mode even it's obviously icon of Macintosh classic, many thanks for additional effort and i wish you all the best!

You're seeing a default icon that is used when Affinity64 is unable to retrieve a files icon or the .Exe file doesn't have an icon. In v1.01 the default icon has changed and the program should now be able to get icons for most 64-bit programs.

Affinity 64 is based on Set Affinity II and I haven't tested it much at all.
Cheers, Ed

I've been using Set Affinity II for some time now.
On Vista sp1 x64 home premium with an intel 9540 (4 cores).
It's great and works fine.
Just one little annoying thing: it
cannot automatically startup because vista blocks it.
Something to do with not properly signed applications. 
Maybe this could be helped when installing the program with a proper installation tool.

I would like to make the programs more Vista/Win7 friendly but I have no plans to do so. Most likely the program will have to be run as Administrator type user and have UAC disabled for the Start with Windows option to work.
Cheers, Ed
I used Set Affinity II for a couple of months - using Vista 32 - and it's been amazing.
Upon start now I get the following error:
CPU Usage Query Failed"
Any idea what it means please?
Regards, Antonio

Awhile back a WinXP user emailed me with the same problem. IIRC when he ran Windows "Performance" monitor (in admin tools section) the CPU usage didn't work there either.

He said he fixed it using the info found on MS site here,
How to manually rebuild Performance Counter Library values

I've never had the problem and don't use Vista or Win7, so really can't offer any other help except to try the newer
Set Affinity II v1.039 as it should bypass and disable CPU usage in the program if it fails to work.

Just a note, our PriFinitty2 program uses a different approach but only shows the total CPU usage, or CPU usage per program.
