Windows XP can run slowly when attempting to access a folder that contains a large number of AVI (Audio Video Interleave) media files. This tweak speeds the process up by stopping Windows from extracting file information from AVIs.

Open you registry and find the key below.

To disable file information extraction rename the key and place a minus sign infront of the current name (i.e. "-{87D62D94-71B3-4b9a-9489-5FE6850DC73E}").

Restart Windows for the change to take effect.

Settings: System Key: [HKEY_CLASSES_ROOT\CLSID\{87D62D94-71B3-4b9a-9489-5FE6850DC73E}]

This setting controls whether hidden files and folders are displayed in explorer when browsing the file system.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'Hidden' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.

Settings:
User Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\
Advanced]
Name: Hidden
Type: REG_DWORD (DWORD Value)
Value: (1 = show hidden, 2 = do not show)

Windows Me and XP include a built-in feature to manage compressed ZIP files and folders. This tweak allows you to disable it and install a third-party application.

regsvr32 /u zipfldr.dll

To enable ZIP folder support run this command:

regsvr32 zipfldr.dll

Restart Windows for the change to take effect.

This command allows you to create a shortcut or execute from a batch file a Windows DLL that will bypass the standard Start Menu method of shutdown and initiate a Log Off, Shutdown or Restart.

For Windows 98 & Me
Either execute the following command from a batch file or create a new shortcut, by right-clicking on the descktop and selecting New -> Shortcut. With the command:

C:\WINDOWS\RUNDLL32.EXE shell32.dll,SHExitWindowsEx x

Where x is either 0, 1, 2, 4 or 8 (or a combination) based on the following table:

0 - Log off: Shuts down all running processes, then logs the user off.
1 - Shutdown: Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped.
2 - Reboot: Shut down and restart the system.
4 - Force (Win98 Only): Forces processes to terminate. When this flag is set, Windows does not query running applications to inform them that Windows is shutting down. This can cause the applications to lose data, therefore, you should only use this flag in an emergency.
8 - Power Off (Win98 Only): Shuts down the system and turns off the power. The system must support the power-off feature.

Click Next and enter the name you want to call the icon (e.g. Shutdown).

For Windows 95
Repeat the steps above but use the command below for the target.

C:\WINDOWS\Rundll32.exe User,ExitWindows

Note: The values above can be combined together to achieve different results. For example, to restart Windows forcefully, without querying any running programs, use the following command line: "rundll32.exe shell32.dll,SHExitWindowsEx 6" (i.e. 2 + 4)
