NOT a big fan of driver update utilities -- I'd rather have more control or hands-on -- but after recently searching, & failing to find a newer Bluetooth driver for one of our devices, I figured I'd give Driver Techie Pro a try. On the plus side it did find that Bluetooth driver. On one device dating from around 2015 I think, using a lowly Intel Atom CPU [we used it for years as a Blu-ray & media player], the app found a newer driver for the network adapter, along with a few more updates that were for the most part inconsequential. On the 2nd device, an Dell AIO, also dating to about 2015, besides finding the Bluetooth driver it found 9 more updates. I have no idea what several of them were for, since the app's window is too small, & won't enlarge to see the cut off text. And there was a problem child, allegedly a newer HD Audio driver, it to forever & ever to download, allegedly installed successfully, but I couldn't find a hint of it on the system drive. It wasn't in the 2 Windows temp folders, not in Program Data or the User folders -- Driver Techie Pro stores the drivers it downloads in it's folder in Users\ [UserName]\ AppData\ Roaming\ -- and I couldn't find anything audio updated in Device Mgr. Concerned that it might have mucked something up, I tracked down & installed the latest Realtek driver I could find. While it did find that Bluetooth driver, the device's WiFi uses the same chip, & it did not update the WiFi driver, so overall the lone plus is outweighed by the minuses.
Driver Techie Pro 1.0.1.8 itself installs to the program's folder & the User folder mentioned earlier, with very few new registry entries -- the app isn't listed with the other installed software in Settings -> Apps for example.
[FWIW, this one was a project... got hit with a forced update in my Win10 VM, so I updated & compacted that so I could finish the initial testing, then updated Win11 on the 1st device before I added Driver Techie Pro & tried it. Then there was the mystery forever download on the 2nd device, where I spent time trying to figure out what happened, then tracked down & installed the audio driver. Phew...]
