2. The 4335 Rule
This trick may not work on all computers
This has been surprising users for quite some time. When you enter a few secret codes, notepad hides them.

3. Open a file using notepad
Here is a simple trick to open any file or program with notepad.
Open notepad and type the following:
Start path of file
Then save the file as Shortcut.bat
Please note that the file type should be kept as ALL FILES while saving it as a .bat file.
Change path of file with your actual file path. For example if you have a file called run with an extension .exe in the folder TEST in C:\ drive, then your path should be something like this: C:\TEST\run.exe
If you want to open some complicated programs such as Firefox, then use this code:
START /d “path of folder” program.extension
Change path of folder with the actual path of the folder, and put the name of the program with its extension. For example if you have a file called run with an extension of .exe in the folder TEST in C:\ drive, then your code should be something like this: START /d “C:\TEST” run.exe

This trick may not work on all computers
Lets say you want to lock a folder named PICS in your D:\ drive , whose path is D:\PICS
Then the code should be something like this:
ren pics pics.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Pics is your folder name. Use the name of the folder in place for pics. Save the text file as lock.bat in the same drive.
To unlock this locked folder:
Open another new notepad text file and type the following:
ren pics.{21EC2020-3AEA-1069-A2DD-08002B30309D} pics
Save the text file as key.bat in the same drive. Here again, pics is the name of the folder. Change it to the folder you want to lock.
8. Make a fake Virus POP UP
Type the following code in notepad:
@echo off
msg * WARNING
msg * VIRUS ENTERED YOUR PC
Save the file as pop.bat and run it. You should get two pop up messages. There has been an issue on some computers, but it should work on most computers.
9. Create a command prompt Virus message
Type the following in notepad:
@ echo off
title Virus
echo Your system is affected by virus
PAUSE
echo:
echo Windows will now try to undo changes
PAUSE
echo:
echo FAILED !
PAUSE
echo:
echo Your system is corrupt

10. Test your antivirus by EICAR STANDARD ANTIVIRUS TEST
Now, you can check if your antivirus really works. Type the following in notepad:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
Save the file as virus-test.txt
Scan the file. If your antivirus detects this file as a virus and tries to remove it, then you can be sure your antivirus is a good one. This is a much easier way, than actually downloading a virus to test it. This sample virus code is perfectly harmless and allows you to test your antivirus. A good antivirus like MS Security Essentials will detect this test virus even before you scan it.
That's all the tricks I'm sharing, at least for now. All the tricks above are perfectly safe and will not harm your computer in any way. There are many destructive notepad tricks as well, like making a real virus which kills the Operating System, but personally, I believe that is only meant for developers who want to make their OS security better.
