1. Disable non-essential startup items through Task Manager to improve boot speed and system response; 2. Adjust visual effects to optimal performance in system properties to reduce graphics resource usage; 3. Use disk cleanup tools to delete temporary files and perform defragmentation to improve hard drive efficiency; 4. Turn off Windows Update automatic checking and delivery optimization functions in Update and Security to reduce background resource usage; 5. Select a high-performance power plan and set the minimum processor status to 100% to ensure full release of hardware performance.

If you find that your Windows 8 system is running slowly and has longer response times, it may be caused by too many background programs, disk fragmentation, or improper system settings. Here are the optimization steps for this problem:

Running environment of this article: Dell XPS 13, Windows 8.1

1. Manage startup items

Reducing unnecessary programs from automatically loading when the system starts can significantly shorten the boot time and improve system fluency. Free up memory and CPU resources by disabling non-critical startup items.

1. Press the Ctrl Shift Esc key combination to open the Task Manager.

2. Click the "Startup" tab to view all programs that start automatically at boot.

3. Right-click the unwanted program and select "Disable", especially the update service or assistant application of third-party software.

2. Adjust visual effects for optimal performance

Windows 8 has a variety of animations and visual effects enabled by default, and these effects consume graphics resources. Setting it to "Best Performance" can reduce the burden on the system, especially for integrated graphics devices.

1. Right-click the "Computer" icon and select "Properties".

2. Click "Advanced System Settings" on the left.

3. Click the "Settings" button in the "Performance" area.

4. Select "Adjust for best performance", or manually uncheck items such as window animation, transparency effects, etc.

3. Perform disk cleaning and defragmentation

Temporary files and disk fragments will reduce the efficiency of hard disk reading and writing. Regular cleaning and defragmentation can effectively improve system response speed, especially for devices using mechanical hard disks.

1. Enter "Disk Cleanup" on the start screen and click on the search result to open the tool.

2. Select the system disk (usually C drive), check "Temporary Files", "Recycle Bin", "System Cache" and other items, click "OK" and confirm the deletion.

3. After completing the cleanup, enter "defragmentation" in the search box and open the "Disk Defragmentation Tool".

4. Select the system disk and click "Analyze Disk". If the fragmentation rate is high, perform the "Optimize" operation.

4. Turn off system update and delivery optimization

Downloading updates in the background of Windows Update will occupy a lot of network and disk resources, and the delivery optimization function may also share bandwidth with other devices, affecting overall performance.

1. Go to "Control Panel" > "Update and Security" > "Windows Update".

2. Click "Change Settings" and change the update mode to "Never check for updates" or only notify downloads.

3. Return to the "Update and Security" page, enter the "Delivery Optimization" settings, and turn it off completely.

5. Optimize power plan

Power management mode affects CPU frequency and hardware performance output. Using "High Performance" mode ensures that the system is always running at maximum performance.

1. Right-click the "Power" icon on the desktop and select "Power Options".

2. Select the "High Performance" power plan. If it is not displayed, click "Create Power Plan" and select the "High Performance" template to create it.

3. Click "Change Plan Settings" > "Change Advanced Power Settings", expand "Processor Power Management", and set "Minimum Processor State" to 100%.
