I planned to try the frequent advice to do as much work as possible in a "Standard user" account, rather than in the "Administrator" account.
I created a new account, "me_Standard". On opening the account, I found that I could not access any of "my" personal files. That seems fair enough. I should probably have guessed that would happen
So, I deleted the new "me_standard" account. I'm now thinking about the possibility of downgrading my "me_Administrator" account to a Standard account.
But is that going to make any difference?
Here is the description of UAC from "Help and Support":
"User Account Control (UAC) is a feature in Windows that can help prevent unauthorized changes to your computer. UAC does this by asking you for permission or an administrator password before performing actions that could potentially affect your computer's operation or that change settings that affect other users."
Currently, as Administrator, I need to click the UAC popups that appear frequently. (I'm not complaining. I know the reason for the UAC.) If I downgrade to a Standard user, I will still need to click the UAC (and probably need to give an Administrator password). Again, I don't mind doing that. But what will I gain in terms of security?
Another frequently-mentioned reason to use a Standard account is that it restricts viruses and malware to the account of the current user.
However, I'm the only user of this laptop, so there are no "other users" to protect.
