About windows Firewall/internet connection sharing ICS can't start

Recently, my computer (XP SP2) has a situation, and a SVCHOST.EXE application error message pops up on the Internet. Similar to the memory error prompt, the network cannot be accessed immediately after the point is determined, the dialer cannot be opened, and the ICS is set from the dialer properties, the control panel, and the system firewall is displayed: windows Firewall/internet connection sharing ICS cannot be started, must Restart the computer, but after a while, this will happen again.

If you do not restart, but log off and then start, the sound icon in the taskbar disappears, and any audio and video files can not be played. In addition to the system sound when starting, there is no sound anymore.

In the face of this situation, I went to Baidu for a multi-party search, summed up the following reasons:

1, the virus went into safe mode antivirus

2, the system has an error Using System Restore

3, the registry error needs to be manually fixed

But I think the most useful is this Article 4, to Microsoft upgrade system, huh, huh~

You may not know that Microsoft has another vulnerability recently. This situation is caused by this vulnerability. After the upgrade, the problem disappears. Some people say that they do not know which program to upgrade.

Open Control Panel Point Security Center Select Automatic Update Settings at the bottom Select Notify me when there are downloads available, but do not download and install them automatically. After a few minutes, the system prompts you to download and install the patch. After the installation, the problem disappears. . . . . . . . . . . . .

Or upgrade from here:
