How can I limit Windows 7 x64 to use only one core of one CPU?
I already tried this and rebooted but it seemed to have no effect. Task Manager still shows four columns that were all in use from time to time, and Device Manager still showed all 4 cores. And my BIOS setup does not have any option I can tweak.
(I have an Intel Core i5 520M.)

Never mind!
Silly me -- I had adjusted the setting for Windows 8 instead of Windows 7 in
msconfig
!Selecting the correct OS and setting the maximum number of processors definitely works.
