A log file will also be created wherever you decide to run SMBCheck from and will look similar to:
SMBCheck Log v22.214.171.124 Current User: MajorGeeks EULA: ACCEPTED C:\WINDOWS\system32\drivers\srv.sys exists. Actual Version: 6.2.14393.1770 Expected Version: 10.0.14393.953 System is patched.
SMBCheck is portable and runs in the command prompt, so you might want to Run as administrator. You will be given details, including Windows operating system, version, expected version, and whether your system is patched or not.
