Alternative method to create a shutdown timer or simply computer shutdown shortcut
Step 1: Right click on your desktop and choose “New=>shortcuts”.
Step 2: In the box that says “Type the location of the shortcut”,
type in “shutdown -s -t 3600” without the quotation marks and click next.
Note: 3600 are the amount of seconds before your computer shuts down. So , this means 3600 seconds = 60 mints (1 hour). You can change the value in the above code. You can even create multiple shutdown shortcuts. For example a computer shutdown shortcut for 30 minutes, 1 hour, 2 hours, 5 hours etc.,
Step 3: Make up a name for the shortcut and you’re done.
Optional Step 4 : You can change the icon by right clicking=>properities=>change icon=>browse
To abort or cancel the shutdown:
To make an abort key to stop the shutdown timer just create another shortcut and make
the “location of the shortcut” to ” shutdown -a” without the quotes.

Click Start then Run and type "gpedit.msc" without quotes. This opens the group policy editor.

Then go to:
--> Local Computer Policy
--> Computer Configuration
--> Administrative Templates

--> Network

--> QOS Packet Scheduler

--> Limit Reservable Bandwidth.
 
Double click on Limit Reservable bandwidth.

 It will say it is not configured, but the truth is under the 'Explain' tab i.e." By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."
So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%.It works on Win 2000 as well.
