The reason for the high CPU usage of WinXP system and the solution

In the process of using win xp system, the user finds that the system is slow to use, and when the task manager process is viewed, the CPU resource occupancy rate is reached. 100%, the system load is too heavy to slow down the system's running speed, how to solve this problem? How do users solve the problem based on their own experience?

Several possibilities for high CPU usage:

1. Anti-virus software causes malfunctions

Some anti-virus software randomly monitors web pages, plug-ins, and emails. The system burden, such as Kaspersky and other anti-virus software performance is more prominent, bringing invisible trouble to users.

Processing: There is basically no reasonable way to deal with it. Try to use the least amount of monitoring services, or upgrade your hardware.

2, the driver is not certified, resulting in 100% CPU resources

A large number of beta drivers flooded the Internet, causing difficult to find the cause of the failure.

Processing: Especially for video card drivers, it is recommended to use Microsoft-certified or officially released drivers, and strictly check the model and version.

3, viruses, Trojans caused a large number of worms to quickly replicate within the system, resulting in high CPU resource utilization rate.

Processing: Thoroughly clean the system memory and local hard disk with reliable anti-virus software, and open the system setting software to check whether there is abnormal startup. Regularly update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, master the correct anti-virus knowledge, and avoid Trojan interference. 4, control panel & mdash; management tools & mdash; service & mdash; RISING REALTIME MONITOR SERVICE Click the right mouse button, change to manual.

5, Start -> Run -> msconfig -> Start, close unnecessary startup items, restart.

6, view & ldquo; svchost & rdquo; process.

svchost . exe is a core process of Windows XP. Svchost.exe does not only appear in Windows XP, but svchost.exe exists in Windows systems that use the NT kernel. Generally, the number of svchost.exe processes in Windows 2000 is two, and the number of svchost.exe processes in Windows XP has risen to four and four.

7, View Network Connections

When a computer with Windows XP is installed as a server, when it receives a connection request on port 445, it allocates memory and allocates a small amount of CPU resources. Serve these connections. When the load is too heavy, the CPU usage may be too high because there is an inherent trade-off between the number of work items and the responsiveness. You need to determine the appropriate MaxWorkItems settings to improve system responsiveness. If the value set is incorrect, the server's responsiveness may be affected, or a user may have too much system resources.

To solve this problem, we can solve it by modifying the registry: expand the [HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\lanmanserver] branch in the Registry Editor, and create a new name in the right window. “maxworkitems” DWORD value. Then double-click the value, type the following values ​​in the open window and save and exit:

If your computer has more than 512MB of memory, type "1024""; if your computer's memory is less than 512 MB, type "ldquo;256".

The high CPU usage of win xp system may be caused by viruses, hardware problems or improper system settings. The above content describes the solution in detail from the hardware, software and virus. I hope to help users.
