Using Tweaking.com – Windows Repair:

When you first run the program you will be introduced to 4 steps before the 
repair options. These steps are highly recommend to do before attempting any 
repairs.

Step 1. Clean Your System Of Infections.

Trying to fix a system that is currently infected is obviously a very bad idea and can make things worse. An infection can hijack a machine and keep part of the repairs from running correctly. Since only part of a repair will work the other part that failed could end up causing problems. Rule of thumb before working on a system is to make sure it is clean. Even if you think your system is clean doing a scan before hand is a good idea.

Step 2. Check File System

Doing a check disk on the hard drive is a good idea. This will have Windows check the file system on the drive fixing any problem it finds. Corrupt files can break a lot of things, including the repairs. So making sure the file system is good is a must.

Step 3. System File Check (SFC)

The built in Windows system file checker is a tool that checks that the Windows files are intact, the correct versions and not corrupted. This is a good idea to do before doing repairs as if a file is corrupt and we try a repair that needs that file then the repair will fail.

Step 4. System Restore

Doing a system restore point is a great idea to do before doing any repairs. If any unforeseen problems happen after any repair than a system restore can put the system back to the way it was before the repairs. This is highly recommended.

Start Repairs

In this final step you can choose between 3 modes.

Basic Mode: This will run only the most basic, safe repair options. Extra advanced repairs are disabled.

Advanced Mode: Runs more advanced repairs while leaving a few disabled.

Custom Mode: Every repair is available. The program will remember your repair choices the next time you choose custom mode.
