System Verifier is a small-sized application capable of detecting various components that were installed incorrectly. It's capable of verifying DirectShow filters, Windows file associations and Windows Search service property handlers.

However, it's not designed to resolve issues, so you should resort to another program capable dealing with this sort of tasks.

The downloaded package consists of a single .exe file that can be saved to a custom folder on the disk or to a USB flash drive to launch it on any PC effortlessly.

Just keep in mind that .NET Framework must be installed, otherwise it won't run. It doesn't generate files on the disk or integrate new entries into the system registry. To be able to uninstall it, you just have to delete this object.

When it comes to the interface, System Verifier has a standard .NET Framework form split into two tabs for configuring settings and viewing results. It has a simple design and layout that makes it easy to use by anyone, even those inexperienced with such software.

It's possible to include or exclude any items when it comes to extension registration for DirectShow filters, extension handler mapping for Windows file associations, and Windows Search Service.

The scanning operation can be triggered with one click. Once it's over, you can inspect results to find out the name and description of each issue. Clicking an entry reveals additional details about a specific problem, such as unregistered file extensions.

It carried out scanning operations swiftly in our tests while remaining light on system resources consumption. No error messages popped up and it didn't hang or crash. Thanks to its intuitive interface and options, System Verifier can be easily handled by any users interested in finding and debugging invalid components which belong to Windows.
