CBS.log file Access Denied [solved]

Click the START orb icon and in the searchbox type “cmd” and you’ll see the program appear in the search results above.
Right-click the cmd program link and select Run as Administrator.
When the Command Prompt comes up, type “notepad %windir\logs\cbs\cbs.log” and hit enter.

The file should open up.

ADVANCED:

The cbs.log file has many log entries and sometimes you only want to see Windows Resource Checker program results (SFC).  To do this, you will search inside the entire CBS.log file and output the SFC lines to a new text file.  Here’s how:

In the Command Prompt window, type “findstr /c:”[SR]” %windir%\logs\cbs\cbs.log >sfcdetails.txt”

Note: This will create the sfcdetails.txt file in the current folder location.  Just navigate to the file and open it like normal.
