 ### Step 6: Repair or remove unsigned drivers
 
 Check for any unsigned drivers, and repair or remove them. Drivers might not be properly signed in the following circumstances:
 
 - You disabled driver signature verification (highly not recommended).
-- A catalog file (file that has a *.cat extension) that's used to sign a driver is corrupt or missing. If a catalog file is corrupt or missing, the driver appears to be unsigned, even though it should be signed.

 1. In the File signature Verification tool, select **Start**.
 1. After the tool runs, it provides a list of the names, locations, and versions of any unsigned drivers that it found. To see the log that the tool created, select **Advanced** > **View Log** (the log includes the unsigned driver information, and might also list the associated catalog files).
-1. The next step is to check that the identified drivers have problems. In some cases, the problem might be related to the catalog file instead of the driver itself. To perform a detailed driver check, download [sigcheck.zip](https://download.sysinternals.com/files/Sigcheck.zip) and extract the tool to a directory on your computer, for example: C:\sigcheck.
