Quick Launch bar in Windows 7 keeps disappearing after every restart

Hi aquarianuw,

Welcome to Microsoft Answers.

I would suggest you to use the below mentioned methods and check if this resolves your issue –

Method 1: Perform a SFC Scan 

1.      Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow

2.      Type the following command, and then press ENTER:

sfc /scannow 

A message will appear stating that 'The system scan will begin'. Be patient because the scan may take some time

3.      If any files require a replace SFC will replace them. You may be asked to insert your Win7 DVD for this process to continue

4.      If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations" 

5.      After the scan has completed, close the command prompt window, restart the computer and check.
