How to Manage Processes Like an IT Professional
Now that you understand what Task Manager offers, let’s learn how to manage processes professionally. These techniques are particularly valuable when running demanding applications on business laptops or workstations.
Setting Process Priority
To change the priority setting of a process:
- Go to the Details tab
- Right-click a process
- Select Set Priority
- Choose your desired priority level
When and Why Priority Matters
Understanding priority levels helps you optimise performance:
| Priority Level | When to Use | Risk Level |
|---|---|---|
| Realtime |
Time-critical tasks
|
High - Can freeze the system
|
| High |
Games, rendering, encoding
|
Medium - May starve other apps
|
| Above Normal |
Creative applications
|
Low
|
| Normal |
Standard apps
|
None
|
| Below Normal |
Background tasks (cloud sync, launchers)
|
None
|
| Low |
Idle tasks
|
None
|
⚠️ Important:
Avoid Realtime priority—it can overwhelm your system and cause instability by blocking essential Windows processes. This can be mitigated by using CPU affinity.
What Is CPU Affinity and How Do You Set It?
CPU affinity allows you to assign specific processor cores to particular applications, giving you granular control over system resources. This is especially useful on multi-core desktops where you want to dedicate cores to specific tasks.
To set CPU affinity:
- Open the Details tab
- Right-click a process
- Select Set affinity
- Check the CPU cores you want to use
Assigning affinities along with priorities gives you immense control over your system performance, whether you’re working on an HP EliteBook or a powerful desktop workstation.
End Task vs End Process Tree: What’s the Difference?
Most users are familiar with ending tasks, but did you know you can kill the entire process tree? This makes it easier to eliminate unwanted processes and everything running with them.
End Task: Terminates only the selected process
End Process Tree: Terminates the process and all its child processes
When you end a task but it keeps respawning, there’s likely a child process reinitialising it. This usually happens with malware or corrupted installers. Using the “End Process Tree” command eliminates the programme along with all child processes.
Performance Monitoring: Reading Task Manager Like a Pro
The Performance Tab displays real-time resource analytics that help you view CPU thread activity, GPU load, disk transfer rates, network throughput, and memory allocation to detect bottlenecks and performance anomalies. Understanding these metrics is crucial whether you’re running a gaming desktop or a business workstation.
How to Interpret Performance Tab Graphs
| Section | What Does It Show |
|---|---|
| CPU |
View logical processors, base speed, and utilisation per core
|
| Memory |
Shows you a comparison between available, committed, and cached memory
|
| Disk |
Shows the activity time and transfer rates of the disk installed
|
| Network |
Assesses and displays the upload and download speeds, along with your IP, and adapter statistics
|
| GPU |
Shows you the engine usage that is being utilised for 3D, and video decoding, along with the VRAM consumption
|
Advanced Resource Monitoring Techniques
For advanced users who want complete control:
- Open Resource Monitor by navigating to Task Manager → Performance → Open Resource Monitor
- In the Performance Tab, select CPU, right-click the graph and select “Change Graph To” → “Logical Processors”
- Right-click the graphs again and select “Copy” → “Paste Into Diagnostics”
Identifying Bottlenecks
Understanding system bottlenecks helps you make informed decisions about upgrades:
- CPU at 100% = Process overload
- Disk at 100% = Storage bottleneck
- Memory capped = System paging to disk
If you’re experiencing consistent bottlenecks, consider upgrading to a more powerful system. The HP Envy Desktop offers excellent performance for creative work, whilst the OMEN 45L provides extreme performance for gaming and demanding applications.
How Can Task Manager Help Detect Memory Leaks?
Memory leaks occur when software fails to release memory, causing increased usage over time even when idle.
Indicators of memory leaks:
- Commit size steadily increases
- Memory usage never decreases
- Performance slows after hours of use
- Closing the app doesn’t release memory
Modern systems like the HP Pavilion All-in-One come with ample RAM to handle memory-intensive tasks, but identifying leaks remains important for long-term system health.
Customising Task Manager for Maximum Efficiency
You can customise Task Manager for better monitoring and performance efficiency by enabling hidden columns in the Details tab. This is particularly useful for users managing business desktops or monitoring multiple processes simultaneously.
Hidden Columns You Should Be Using
Top 5 hidden columns to enable:
- Power usage - See which apps drain battery
- Power usage trend - Identify long-term power hogs
- GPU engine - Track GPU workload distribution
- Command line - View process launch parameters
- Publisher - Verify process legitimacy
To enable these: Right-click any column header in the Details tab and check the desired columns.
Optimising Power Management
For laptop users, particularly those with portable models like the HP Pavilion Aero 13, monitoring power usage is essential. The power usage columns help identify applications that drain battery unnecessarily, allowing you to optimise for longer unplugged sessions.
Startup Optimisation: Analysing and Controlling Startup Programmes
Optimise your PC’s boot time by managing startup programmes effectively. This is especially important for all-in-one desktops and shared family computers where multiple programmes compete for resources at startup.
How Does Task Manager Calculate Startup Impact?
Task Manager uses these metrics to calculate startup impact:
- Disk I/O usage during boot
- CPU time consumed per app
- Frequency of startup execution
Which Startup Programmes Can I Safely Disable?
Safe to Disable:
- Game launchers (Steam, Epic, Origin)
- Music streaming apps (Spotify, Apple Music)
- Update checkers
- Cloud sync services (when not needed at startup)
