Windows 7 Update Settings Disabled (Important Updates Grayed Out)

This worked for me:

1) Hold WindowsKey + R 
    (is hold Start & press R on your keyboard)

2) Type: “regedit”
Hit Enter

3) Go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Find AUOptions. 
Double Click AUOptions or Right Click Modify

> You can change the values data from 1 through 5 <

1. Download updates but let me choose wether to install them
2. Check for updates but let me choose wether to download and install them
3. Download updates but let me choose wether to install them
4. Install updates automatically / Never Check For Updates
5. Enable the option box to choose manually

(Note: Option 1,2,3 & 5 did not give me the option for Never Check For Updates. I chose 4 at the end because I want Never Check For Updates)
