in my case - driver update did not bork my system, but there are many drivers listed as "out of date" even though my installed version is greater than the "latest" version reported available by CCleaner. Perhaps this results from manually installing latest versions from PC component OEM sites (e.g., Intel, Asus) -- so CCleaner should look at multiple sources for popular component makers, or at least take the stringified versions from the reportedly installed and latest versions -- and check the numeric equivalent on each segment of the version numbers before reporting a driver is out of date (e.g. installed 10.1045.2 is greater than 10.1030.5).
