Hi Desperado,

I understand that you want to try Driver Reviver as a free tool to quickly scan your PC to identify out of date and obsolete drivers.
It will quickly update these drivers to restore optimum performance to your PC.

Yes, you can download the free, trial version of Driver Reviver and use it but for limited functionality such as showing the outdated drivers in your PC.

The free, trial version allows you to perform a full system scan to see if there are any driver updates available for your computer.

You can only use the features are which are present in the free trial, for using more features you need to unlock them by buying the product.

You will need to purchase a license code for Driver Reviver to be able to download and install the driver updates available for your computer.

I hope this helps.

Regards,
Lokesh
