Enable Standard User to Run a Program as an Administrator

First

Create a Batch File “C:\myprogram.bat” with the following line in it (make sure you replace notepad with your own program):

runas /user:COMPUTERNAME\Administrator /savecred "C:\Program Files (x86)\Notepad++\notepad++.exe"

Second

The first time you run the batch file above you will get prompted for your administrator password.

Run the Batch File first, so you can register your password.

Third

Disable the annoying DOS Prompt. Create another batch file and put the following lines in it:

Set WshShell = CreateObject("WScript.Shell" ) 
WshShell.Run chr(34) & "C:\myprogram.bat" & Chr(34), 0 
Set WshShell = Nothing

Voila. You are good to go.

MD5 Quick Facts

Number of possible an md5 string:

16 possibilities for each digit (0-9 (10 possibilities) and A-F (6 possibilities)), there are a total of 32 digits
so the number of possible combinations is :
16 ^ 32 : 3.4028237 * 10^38

Another way you could calculate it is:

Each Digit of an MD5 represent 4 bits (Hexadecimal). So for 32 digits we have a total of
32 * 4 = 128 bits
so 
2^128 = 3.4028237 * 10^38
