Disable User Account Controls in Windows 7 or Vista

• 1). Save all open data and close all programs.
  
  
• 2). Click the "Start" button and select "Settings" and "Control Panel." Double-click "User Accounts." This opens a Control Panel program window.
  
  
• 3). Click "Turn User Account Control on or off." This opens a new program window.
  
  
• 4). Uncheck the box next to "Use User Account Control (UAC) to help protect your computer" and click "OK." Click "Restart now." When your computer reboots, you can access the Chkdsk system tool.
  
  

Run Chkdsk

• 1). Click "Start" and "Run" to open the command prompt.
  
  
• 2). Enter "CHKDSK C: /F > C:\CHKDISKLOG.TXT" and click "OK."
  
  The Chkdsk utility checks your hard disk for physical integrity and file structure quality. Chkdsk automatically attempts to fix any disk problems it encounters and includes this information in the log file.
  
  If you are checking a disk that is in a drive location other than "C:", substitute the appropriate drive letter in the command.
  
  
• 3). Navigate Windows Explorer to the "C:" directory and double-click the "CHKDISKLOG.TXT" file to review the log file containing the results of your Chkdsk operation.
  
  
• 4). Repeat the procedure from Section 1 and recheck the "Use User Account Control" check box.
