Local Security Method to Enable the Administrator Account
Kindly sent in by Dave Waddell
If you prefer a simpler method, visit the Local Security policy, incidentally, this MMC is worth exploring in its own right.

This is how you navigate to the Local Security Policy. 
Firstly click on Vista's Start orb, then in the Start Search dialog box type: secpol.msc.  Note: you must include the .msc extension.

Secondly drill down to Local Policy, Security Options

Thirdly double click Accounts: Administrator account status, and select enable.

 

1, Start > type "memory" on search box.

2. Click on the Memory Diagnostic Tool GUI that will pop-up.

3. Restart now and check for problems with memory.

Forgot Your Windows Password?
A lot of people think that after having lost their Windows admin password, they absolutely have to reinstall their OS. Let me tell you something: They are wrong! Here I’m posting a few methods / utilities which can be used to recover Windows password:

 

1st Method:

The first thing which you check if you forget login password. When we install Windows, it automatically creates an account “Administrator” and sets its password to blank. So if you have forgotten your user account password then try this:

 

Start system and when you see Windows Welcome screen / Login screen, press ++ del keys twice and it’ll show Classic Login box. Now type “Administrator” (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.

 

Now you can reset your account password from “Control Panel -> User Accounts”.

Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

 

 

Right before the Welcome Screen, try pressing Ctrl + Alt + Del three times. This will show a screen that will ask for the default Username and Password. Type "Administrator" as username, and leave password "blank".

 

If able to enter Windows, proceed to the Control Panel. Create User Accounts with Passwords. Also create a User Account without password.

 

Always login not as administrator to avoid being hacked. Use admin account only for editing or adding important files into your system.
