How to check if WinXP files have been "signed" by Microsoft Digital

There are a lot of software or drivers in WinXP that have not been digitally signed by Microsoft. Although some software that does not have "signature" does not affect the normal operation of the system, some will cause unknown errors. Therefore, when downloading each software, it is best to check whether the software has passed the "signature". The following small series will teach you how to use the WinXP's own verification tool “Sigverif" to check whether the file has been signed.

In the query results given by the system, you will find that all signed and unsigned driver lists are in the Sigverif.txt file located in the %Windir% folder (usually Winnt or Windows). And all unsigned drivers are marked as “unsigned" (Unsigned).

Once the system prompts an exception, you can restore it back.
