pointless tools from my view. any installed driver is also available as a full package in the web. in special for complex drivers like logitech absolutely useless, it wont run or has no functionality/options.
@ Brummelchen Did you read ALL the info in the link ? It backs up Lots of other associated data etc etc than just the drivers !
tl;dr as long i tried such tools they work same way. i can backup my sound driver but it wont work because setup also installs needed libraries (dll files) which are not set in the INF file.
