Today I continued on my project of trying to find updated drivers for 4 of our devices, this time using Driver Booster 10 PRO. Our 2 main PCs are newer & less complicated, so there's not really much need to hunt drivers through a utility like this, but those 4, 2 tablets, an AIO, & a laptop, have things like touch screen, camera, & battery drivers, which can be pretty hard to come by after the 1st year or two when manufacturers discontinue support [in those cases where they even offer it initially]. Problem is, the original drivers for those sorts of components have a habit of clashing with Windows, either because of Windows updates, or newer versions like Win11. And Driver Booster 10 PRO did find several, though they lean towards sketchy compatibility. Much like driver sites, if company X uses a certain component, & company Y uses something similar, or at least something judged close enough, they'll recommend a driver used by company X for devices made by Company Y. Sometimes that works, sometimes it doesn't -- flip a coin.
Anyway, at best I avoided a few problems down the road -- stuff that might be a problem with a new update or version of Windows, & I **might** have cured a couple of annoyances, though it's too soon to tell, e.g. the battery meter & charging in Win11 on one of the tablets. At the same time a couple handfuls of drivers would not work properly, for example, I wound up spending a couple of hours getting the touchpad working on the laptop again. which is why I generally stay away from these apps. Note that in many cases the old drivers remain in Windows\ System32\ DriverStore\ FileRepository, That's a valuable source if you need the files for the driver that was working before you updated them, but if the driver set is large, e.g., a graphics driver, you might want to delete it to get that space back -- you'll have to set the permissions before you can delete any folder stored there.
In case you want/need to get rid of it, Driver Booster 10 PRO adds the program's folder, plus folders in Users\ [UserName]\ AppData LocalLow & Roaming. You also get 2 folders in ProgramData named IObit & ProductData. The registry didn't get hit hard at all from installing the app, with 62 new entries recorded in my Win11 VM, but activating the app caused a partial rewrite of the registry hive, getting 53k new entries, though just 3 were for IObit.
