With Netsh.exe you can easily view your TCP/IP settings. Type the following command in a Command Prompt window (CMD.EXE):

netsh interface ip show config

With Netsh.exe, you can easily configure your computer’s IP address and other TCP/IP related settings. For example:

The following command configures the interface named Local Area Connection with the static IP address 10.0.0.100, the subnet mask of 255.255.255.0, and a default gateway of 10.0.0.1:

netsh interface ip set address name=»Local Area Connection» static 10.0.0.100 255.255.255.0 10.0.0.1 1 (The above is one long line)

If you want to export your current ip settings:

netsh -c interface dump > c:mySettings.txt 

If you want to import your ip settings:

netsh -f c:mySettings.txt

or instead of -f

netsh exec c:mySettings.txt

Force a shutdown in Windows

rundll32.exe shell32.dll,SHExitWindowsEx 4

The above will shutdown any running processes and shutdown your computer without saving any data or warning. It should only be used if you have problems shutting down normally.

Note the numbers at the end of each of the above command lines. They are what make the different actions possible and they can be combined. The most common combination is using the Force shutdown action with a restart. Restart = 2 Force =4, so you would just add 6 to the end of the main command line:
rundll32.exe shell32.dll,SHExitWindowsEx 6

If your computer supports the power-off feature, you can also use the number 8 which is a Power Off action which will not only shutdown your computer, but turn off the power too.rundll32.exe shell32.dll,SHExitWindowsEx 8

To summarize:

0 = Logoff
1 = Shutdown
2 = Restart
4 = Forced Shutdown
8 = Power Off (Shutdown and turn off Power)
