This setting allows you to manage how the system processor should prioritize foreground and background tasks. This registry tweak might fix your CPU.

For this, go to Start > Run menu, enter “regedit” and navigate to the registry path listed below. Now, right-click and modify the Dword value “Win32PrioritySeparation”, in the right panel, to “12” which can set processor scheduling to “Programs”. However, if you want to set processor scheduling to “Background Service”s, change the value data to “26”.

You can also schedule the processor to serve both foreground and background tasks, as explained below:

Value	Outcome
0	Foreground and background applications equally responsive
1	Foreground application more responsive than background
2	Best foreground application response time

When the value is set to 1, the foreground (active) application has more CPU power than the background (inactive) applications (if any), and if you set the value to 2, you get even more power to the foreground application. The maximum value allowed is 26 in Hexadecimal. You can play around with these values till you find your own suited combination.

NOTE:
Higher settings will drag down system resources considerably, especially when doing something big, like saving a huge Photoshop file.
