The system has become stuttered after updating, which can be solved by troubleshooting resource usage, cleaning caches, and checking drivers. 1. Check the resource occupancy of background processes, use the task manager to view CPU, memory, disk usage, and close high-occupancy processes such as Windows Search and Windows Update; 2. Clean up system caches and temporary files, deeply clean up through disk cleaning tools or execute cleanmgr commands; 3. Update or roll back drivers, update key drivers such as graphics card and motherboard through device manager, or manually install the latest version of the official website; 4. Adjust visual effects and startup items, set them to the best performance and disable unnecessary boot-up programs.

The system has become stuttered after updating, which is a problem that many Windows 10 users have encountered. It’s not that your computer suddenly becomes “old”, but that some settings or background tasks have not been adjusted after the update. The focus is on troubleshooting resource occupation, cleaning up caches and checking driver adaptation.

1. Check the resource occupancy of background processes

After the update is completed, Windows may run some maintenance tasks in the background, such as optimizing system files, index reconstruction, etc., which will occupy CPU and disk resources.

• Open Task Manager (Ctrl Shift Esc) and switch to the Performance tab
• Depending on the usage of CPU, memory, and disk, which one is close to 100%, click in to see which process is causing the blame.
• Common "suspects" include: Windows Search, Windows Update, Antimalware Service Executable, explorer.exe

If it is caused by antivirus software or third-party programs, you can try to temporarily close them to see if they are better.

2. Clean up system cache and temporary files

During the update process, a large number of temporary files and old version system files will be generated. If not cleared, it will not only occupy space, but may also affect the system response speed.

You can do this:

• Press Win S, search for "Disk Cleanup", and select the system disk (usually a C disk)
• Check the options "Windows Update Installation File", "Temporary File", "Recycle Bin" and other options
• Click "OK" → "Delete File"

In addition, you can run the command prompt (administrator permissions) to execute:

 cleanmgr /sageset:65535
cleanmgr /sagerun:65535

This set of commands will clean up deeper system caches.

3. Update or rollback the driver

Sometimes system updates will cause driver incompatibility, especially key drivers such as graphics cards and motherboard chipsets.

Suggest you:

• Open Device Manager (right-click Start Menu → Device Manager)
• Check if there are any devices with yellow exclamation marks
• Click "Update Driver" for key devices such as graphics cards, motherboards, and network cards.
• If it is slower after update, you can right-click to select "Properties" → "Driver Rollback"

If you are not sure which drivers have problems, you can download the latest WHQL certified version to manually install it.

4. Adjust visual effects and startup items

Although some visual effects are good, they will affect the smoothness on low-end machines. At the same time, too many startup items will slow down the startup speed.

Operation steps:

• Right-click "This Computer" → Properties → Advanced System Settings → Advanced → Performance Settings
• Select "Adjust to Best Performance" or manually uncheck unnecessary effects
• At the same time, click "Task Manager" in the "Startup" tab to disable programs that do not require booting.

Basically these common ways of dealing with it. In most cases, the lag after the update will not last too long, but if it does not improve after a few days, further investigations will be made from the aspects of system file integrity, hardware status, etc.
