Countdown timer for shutdown computer

Many a times people like to sleep on music, but the problem is that the comp will continue

running the whole night. Here is how you can create a countdown timer to shutdown your comp in

your specified time.

Go to run in start menu and input this command

shutdown -s -t 3600

this will create a countdown timer which will go off in 3600 seconds (1 Hour). you can replace

the 3600 to any time limit you want the comp to shutdown ,but remember the time should always be

expressed in seconds i.e if u want the comp to shutdown in Half an hour you have to write 1800

and so on...

If you are as lazy as me and don't want to input the command each time, then create a batch file

or shortcut

Batch:
open a notepad and type

shutdown -s -t 3600

now in the files menu select "save as" and save this file as Activate.bat

Just double clicking this file will activate your timer

Shortcut:
On the desktop right click and create a new shortcut. in the location type

shutdown -s -t 3600

Give it any name like "Activate timer"
Again, double clicking this newly created shortcut will do the same.

FORCING THE SHUTDOWN:

another operator that you can use with this command is -f . this will force a shutdown on system.

suppose you want the comp to shutdown as quickly as possible you can give command

shutdown -s -f -t 00

here we have used a -f operator and the delay is set to 0 seconds.

(as we are talking about quick shutdown, u can use command
c:windowssystem32tsshutdn.exe 00 /POWERDOWN /DELAY:00 also)

STOPPING THE TIMER:
Any time when you want to stop the running timer use a -a operator(standing for abort)

the command is

shutdown -a

You can use it in any way u prefer, like direct input in run (or command prompt) , create a .bat

file or create a shortcut on desktop

SOME OTHER OPTIONS:

shutdown -r (restarting)
shutdown -r -t 3600 (timer for restarting in 1 hour)
shutdown -r -f -t 00 (quick reboot)

How To Delete Annoying Multiple Entries in Boot Screen


Suppose you have multiple copies of Windows XP installed in your PC in different drives or

installed Windows XP on top of another operating system like Windows 98 or Windows 2000. Now,

though you may have removed some or all of the older versions, still the boot screen continues to

show the old operating system entries. Isn't it annoying and confusing to remember and select

every time the only right option? Don't worry, here is how you can get rid of the problem

forever:

1. Load windows and login if required
2. Go to Start menu, click on Run and then type cmd. This open up the command window.
3. Type this command:
bootcfg /delete /id x
where x is the number of the option you want to delete. Say, for example, you want to delete 2nd

boot option then you will type bootcfg
/delete /id 2 and so on.
4. Now reboot the machine to check that you have only the correct option(s) available.

Automatic Screen Refresh Tips


When you are working on your local computer and want to refresh any changes in your system

automatically. For example some times you are watching sports results, online Stock Exchange

rates and any changes to your hard drive but these changes are not usually refreshed until you

press the F5 key on your keyboard.

To refresh your screen automatically you should edit your system Registry. But the best technique

to edit the windows registry keys, always export or backup the whole windows registry keys on

backup drive before editing. Because any mistake in Registry can cause serious problem in your

computer to run properly.

Follow the given steps to change the updates automatically.

First click on Start button then type Regedit in Run option.

In Registry Editor panel go to the path:

HKEY_LOCAL_MACHINE / System / CurrentControlSet /

Control / UpdateMode

Here in right hand side panel edit the DWORD value to be between 1 and 5.

Now restart your computer after any changes to go into effect.

-The file will hereby be referred to in all examples as New Text Document.txt

2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here

on this will be referred to as (secret.rar)

3. Open command prompt by going to Start > Run > cmd

4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [ex: cd C:New Folder]

5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)

Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG,

and is a JPEG, yet it now contains your file.


In order to view/extract your file, there are two options that you can take

a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is there.
b) Leave the file extension as is, right click, open with WinRar and your file is there.
