The reason why the system is slower and slower to resolve

The system has been used for a long time. Many users will find that it is getting slower and slower. Many people want to optimize the system for this reason, but they can't find the reason why the system is slow. The slower the coming is caused by what reason, let's take a look. We have learned a few things about the reasons for the slowdown of the computer operating system. I hope that the introduction of these aspects can be a good deal for the reasons why your operating system is slow.

1. NIC

If the settings are not correct, the NIC will obviously affect the system startup speed. If your computer does not need a network card, simply unplug the NIC so as not to affect the system startup speed. .

If your computer is connected to a LAN, after installing the NIC driver, the system will automatically obtain the IP address through DHCP by default, but most companies have no DHCP server on the LAN, so if the user sets Into the "automatically obtain the IP address", the system will continue to search the network for DHCP

server at startup, until the IP address or timeout, naturally affects the startup time, so LAN users are better Specify a fixed IP address for your computer.

2.File and printer sharing

Some computers with Windows XP Professional will also have a very slow startup problem, even reaching 1 minute and 40 seconds! The system seems to be dead. After logging in to the system, the desktop does not appear. The computer just stops responding and can be used normally after 1 minute. This is because the Mrxsmb.dll file has been added for the computer startup for 67 seconds after using the Bootvis.exe program!

To solve this problem, just stop sharing the folder and printer: Select &ldquo Start → set → network and dial-up connection, right-click "local connection", select "property", cancel in the open window "This connection uses the following selected components" “Microsoft Network File and Printer Sharing> in front of the checkbox, restart the computer.

Tip: Microsoft has upgraded the Bootvis.exe file several times, and it does help a lot of Windows XP startup speed

3.USB hard disk and scanner and other devices < Br>

If your computer has a device such as a scanner installed, or if you have connected a USB hard drive at startup, try disconnecting them first to see if the startup speed has changed. Generally speaking, because the USB interface is slow, the corresponding device will have a significant impact on the startup speed of the computer. You should try to connect the USB device after booting. If you do not have a USB device, it is recommended to turn off the USB function directly in the BIOS setup.

Tip: Since each drive (including the optical drive) is detected when Windows starts up, if the CD is placed in the CD drive, it will also extend the startup time of the computer.
