Numbers and Symbols

%SystemRoot%

A universal reference to the directory in which the Windows system files are installed. Typically, %SystemRoot% is C:\Winnt or C:\Windows. By default, clean installations of Windows Server 2003 use the Windows directory. If multiple copies of Windows are installed in a multiboot system, each copy has its own %SystemRoot% directory.

3DES (Triple Data Encryption Standard)

A more secure variant of the DES standard that encrypts data by using three different 56-bit keys in succession. 3DES thus extends the DES key to 168 bits, providing approximately 6.2x10⁵⁷ different keys.
