Favorite maintenance tool?

Latest drivers for what exactly? I manually update GPU drivers from time to time, I don't need external app to do that for me, and all other ones are working fine. All those registry optimizers/cleaners/boosters etc. can potentially do more harm than good if they delete something that they shouldn't have. I'm not using dozens/hundreds of programs for testing or something like that and uninstalling them afterwards so there is not a lot junk to be 'cleaned' in the first place. I probably should use some Windows component to do that once a year or so.

Yeah! It was looooooooooong ago, though.

Check out this old review from 2014

For GPU drivers, I let Nvidia app and Intel Driver Manager take care of it automatically.
For other drivers on my Intel mobo, also the Intel Driver Manager (mostly wifi and Bluetooth, but those are not really necessary)
Windows Update as usual, and Microsoft Store as usual, for most of system/store apps.
You don't need 3rd party apps to mess with your Windows, everything is practically automatic nowadays.
Dism and SFC can take care of possibly corrupt installation files, also deleting junk/obsolete ones in the process, and keeping your Windows install healthy.
Edit: also, don't need to use them all the time. Once every 6 months or so is enough.

Ah, forgot the Microsoft PC Manager app. Get it for free on Microsoft Store, it's from Microsoft itself. It aggregates most (if not all) of Windows built-in cleaning features that are scattered all over windows settings, put them in a nifty systray icon, and even do it all automatically for you if you let it start with windows.
It's good to clean up the caches/temp files.

The only thing i use is Revo Uninstaller that fixes programs leaving junk, only ever update my GPU.
And i personally would never chose "auto" or "quick" update/install for anything.
