Microsoft never looks at or posts to these 8/8.1 forums.
I do not recommend that you use any Registry Cleaners, Optimizers, Driver Updaters, Tune -Up utilities, etc.
They may do more harm to your operating system than any good that they claim to be able to do.

You normally only replace/reinstall drivers if you are having a problem with the existing ones or you require newer features that a newly released driver for a particular device would give you.
A lot of released drivers have never been updated since the year that they were released, but the devices they are for still work correctly.
You should obtain your Driver Software from your Computer or Hardware Manufacturer, not through Windows Update (except for Microsoft Hardware Updates), as Microsoft normally does nor have those latest Drivers available as Microsoft relies on the 3rd Party Hardware Manufacturer to supply them.
Go to your Computer or Hardware Manufacture's website > Driver and Software Support Section > look up your Computer or Hardware Model number > then your Operating System > locate the correct Drivers > download and install them.
