Backup note: I do have my files stored on OneDrive, and that's enough for me, since I'm just using this laptop for university and I don't keep anything else on it.
Hope you approve
@Noxx pretty much pointed out the only thing I would change. Also, the input for OS Firewall should be "3rd Party" rather than "Enabled", as you have ESS9 installed.
Ain't it nice to see a config and something tells you you seen this before? Reminds me of my old config (including OD but excluding backup and extension).
Your config is good as it is but as others said, UAC settings can be turned to default, tho the do not dim desktop version is fine too.
I would however rely on perhaps a pen drive for traditional backup method. I have 2 pen drives of 32 GB each with important stuff, tho it is also backed up on eHDD.
