Sethc is nothing but sticky keys program which is present in system32 files

This hack allows you to access command prompt from a logout screen. Cool :)

Step 1. Goto c:\windows\system32

Step 2. Rename the file sethc.exe to sethc.exe.bak

Step 3. Copy cmd.exe to sethc.exe (You can copy netcat.exe or any executable like explorer.exe to sethc.exe)

Step 4. Now logog off and in <control+Alt+Screen> press the <shift> key 5 times
