and Windows 20,001, XP has an annoying latency problem while browsing the LAN, but it's hard to find information about the problem. If you browse a win 9x machine, for example, enter "\ComputerName" in the address bar of the Network Neighborhood, the XP machine checks "Task Scheduler" on the machine on which it is connecting. This search process can cause up to 30 seconds of latency. If you open a shared resource directly, such as entering "\computernameshare" in the address bar of your network Neighborhood, there is no such delay. To avoid the XP search "Task Scheduler" operation, improve the speed of browsing the network, you can delete Hkey_local_ machinesoftwaremicrosoftwindowscurrentversionexplorerremotecomputernamespace{ D6277990-4C6A-11CF-8D87-00AA0060F5BF} child keys.

In Windows XP, we can use the Modify registry to put the "My Computer" icon on the "My Documents" above, the following steps: Find hkey_classes_root\clsid\{in the registry 450D8FBA-AD25-11D0-98A8-0800361B1103}, then creates a new DWORD value "Sortorderindex" and modifies its key value of "54" (16).

We'll dig it up and we can use it. Open Registry Editor, create a new Double-byte value entry under Registry HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings MaxConnectionsPerServer ", it determines the maximum number of simultaneous downloads, generally set to 5~8 a good number of lines. In addition, for HTTP 1.0 servers, you can add a Double-byte value item named "MaxConnectionsPer1_0Server," which is also used to set the maximum number of simultaneous downloads, or to 5~8.
