Computer slowdown is usually caused by too many startup items, high disk usage, too many background programs, or system problems. Solutions include: 1. Press Ctrl Shift Esc to open the task manager and disable unnecessary startup programs; 2. Pause Windows Search in the service or close SysMain (Superfetch) to reduce disk usage, and upgrade SSD if necessary; 3. Check the Task Manager performance tag, close the background program that consumes high memory, and use lightweight software to replace applications that consume high resource; 4. Run sfc/scannow to check system files, update the driver and clean the cache, and consider reinstalling the system if it is invalid. Following the above steps to check and handle the system can effectively improve the smoothness of the system.

Slowering computers is a problem that many Windows 11 users will encounter. There may be many reasons, but they are usually concentrated in aspects such as too many startup items, high disk usage, improper system settings, or backend programs dragging down. Below are some common reasons and corresponding solutions to help you find out the problem.

Too many startup items, the startup is as slow as a snail

Many people automatically run a bunch of software as soon as they turn on the computer, such as browsers, network disks, antivirus software, communication tools, etc. These software can be seen in the "Startup" tab of Task Manager. If you have more than 5 startup programs, your startup speed will definitely not be fast.

Solution:

• Press Ctrl Shift Esc to open the Task Manager → Click the "Start" tab
• Right-click all software that does not need to be started by turning on and select "Disable"
• Commonly shut down include: Steam, OneDrive (unless you rely on synchronization), various hardware drivers come with their own control center, etc.

Note: Not all software is recommended to turn off, such as certain security software or driver management tools, depending on personal usage habits.

Disk occupies 100%, the system is stuck into a slide

This is a problem that Win11 users often report, especially when you see the "disk" item in the resource monitor that remains 100% occupied for a long time, the system will become particularly stuttered. This may be that system processes such as "Windows Search", "Superfetch", or "Windows Update" frequently reads and writes to hard disks.

Solution:

• Open Task Manager → Performance → Disk → View which process occupies a lot of resources
• If it is "System" or "Windows Search", you can try:
  • Pause the search index: Open "Services" (win R → enter services.msc) → Find Windows Search → Right-click "Pause" or change to "Manual"
  • Close Superfetch: Find "SysMain" (formerly called Superfetch) in the service, right-click and stop and change to "Disable"

If it is a mechanical hard drive, upgrading to an SSD can also significantly improve the response speed.

Too many background programs, not enough memory

Some programs don't seem to be very useful, but in fact they have been running in the background. For example, Edge has opened more than a dozen web pages, WeChat PC version, QQ, video player, design software, etc. After a long time, the memory is full, and the system will naturally slow down.

Suggested practices:

• Check the "Performance" tag in the Task Manager frequently to see memory and CPU usage
• Close unnecessary browser tabs, especially those that automatically play videos or ads
• Use lightweight alternatives, such as swapping Chrome for Edge (more resource-saving), or using lightweight notepad, image viewer, etc.

Also, if your memory is less than 16GB, try to avoid running multiple large programs at the same time.

The system itself cannot be ignored

Sometimes system files are corrupted, updated, or driver incompatible can also cause lag. This situation is relatively rare, but it is also worth checking.

You can try the following steps:

• Run the system file check tool: Open the command prompt (administrator permissions) → enter sfc /scannow
• Update drivers, especially graphics card and motherboard drivers, you can download the latest version through the device manager or official website
• Clean up the system cache: Use disk cleaning tools or third-party tools such as CCleaner

If none of the above methods work, the final choice is to reinstall the system, but remember to back up important data in advance.

Basically, these common reasons and methods are there. Many issues are actually not complicated, but are easily overlooked. First check the startup items, then look at disk occupation, then manage the background program, and finally consider system-level issues. Do it all the time and you should be able to feel a lot smoother.
