Games and applications sometimes compete for CPU resources, especially when multiple programs are running at the same time. If a game feels sluggish or an application responds slowly, adjusting its process priority may help Windows allocate CPU time more effectively.
Windows allows users to change process priority through Task Manager. For a more convenient approach, Wise Registry Cleaner also provides a System Tuneup option to prioritize CPU power for active apps and games. This article explains how to use both methods.
Method 1: Set Priority to High in Task Manager
Task Manager lets you change the priority of a running game or application without installing additional software. Note that this change is temporary and will reset when the app closes.
Step 1. Open Task Manager
Press Ctrl + Shift + Esc to open Task Manager (or right-click the taskbar and choose Task Manager).
Step 2. Change the Priority
Switch to the Details tab. Right-click the target process and select Set priority > High from the context menu. If Windows displays a confirmation prompt, click Change priority to proceed.

Method 2: Prioritize Active Games and Apps in Wise Registry Cleaner
If you want a permanent tweak that prioritizes your active games and apps without manually changing settings every time you launch a game, Wise Registry Cleaner is an excellent alternative. It adjusts how Windows allocates CPU resources to whichever application is currently in the foreground.
Step 1. Download Wise Registry Cleaner
Download and install Wise Registry Cleaner from the official WiseCleaner website.
Step 2. Open System Tuneup
Launch Wise Registry Cleaner. At the top of the window, click on the System Tuneup tab.
Step 3. Find the CPU Prioritization Option
In the System Tuneup list, locate Prioritize CPU power for your active apps and games.
Step 4. Enable the Optimization
Select the checkbox next to Prioritize CPU power for your active apps and games. Click Optimize to apply the selected optimization.

Conclusion
Adjusting process priority can help Windows give more attention to games and applications that need additional CPU resources. Task Manager is useful for setting the priority of a specific running process, while Wise Registry Cleaner provides a simpler way to optimize CPU prioritization for active apps and games. Choose the method that best fits your needs and see whether it makes a difference in everyday performance.
