nielsm posted:The purpose of Program Files being locked down is exactly so you can't modify things in there with regular user permissions. With full write access to the installed software all the time, anything that runs can just modify anything else silently.What kind of things are you doing that involves editing config files (system level, not user level) all the time? As far as I've ever noticed there's nothing stopping regular users from modifying things in PF, all the lockdown only prevent apps from modifying other apps. Sometimes I gotta get in there and change how resolution scaling is being handled and it's never thrown a UAC prompt at me for it.

When you change compatibility settings for a program it's a per user setting stored in registry. Just because the exe file is in PF doesn't mean you're modifying the exe file itself. There is a button to set system-wide compatibility settings instead of per user, you get a UAC prompt clicking that since it stores the settings in HKLM instead of HKCU.

Mr Shiny Pants posted:Yes, but on Linux/Unix it actually works you know. Like sudo actually being pleasant to work with when compared to UAC. Yeah, UAC was annoying way back when Vista launched. Which was apparently actually by design because Microsoft thought that if they annoyed users with UAC notifications, it would push developers to making their software more secure. But it's not 2007. If you have to deal with UAC so often on Windows 10 that it becomes frustrating, you're doing something and/or are using software that you probably shouldn't. It is kind of amazing how much weird stuff there still floating around about UAC. At work someone got some fabulous install instructions for Solidworks from a reseller. According to them he had to: - Disable UAC - Disable the antivirus - Install Solidworks - Leave UAC disabled "to ensure smoother user experience". Activating the antivirus wasn't mentioned anywhere. But the instructions did recommend McAffee at the end.

Buff Hardback posted:Bit late, but disabling the dimming on UAC (aka removing its secure desktop mode) is functionally equivalent to turning UAC off. If it's not running in secure desktop mode, anything else can interact with the UAC dialog meaning that something can just automatically accept it for you. For gently caress's sake. Is this true?

If that's in your Steam folder, it's because of Steam changing its folder to have nonstandard permissions that let anything do everything in there. Mainly because game devs suck at doing it right and Valve doesn't want to deal with people upset that their copy of Hentai Puzzle Slideshow 3 isn't working right.

I'm poking around my folders now that I'm not phone-posting and everything in PF is stuff I don't want to touch like drivers, while my Applications folder is primarily games and game-supporting apps, or stuff that came with self-extractors instead of installers. Guess my installation system isn't secure but it's nothing I'd be worried about if I lost with no backups either.

Yeah, Steam games are the biggest 'have to dig through the folders for something specific' reason, whether it's changing the scaling on the executable or hitting the ini files because some tweaks aren't exposed through the ingame UI. It shouldn't be so complicated just to get borderless windowed mode but it is what it is sometimes.

You end up with ransomware by not keeping your software up to date, installing poo poo off the internet, or just being really unlucky and encountering a 0-day vulnerability in your browser or whatever.

Not quite, sometimes you get some EternalBlue poo poo and an attack goes from zero to owned with no stops or waiting. But that's what computer security is about, nothing is ever perfect but everything you do to add defense in depth is a help. If you follow every one of the best practices you're still not invulnerable. Your chances of getting hit are reduced. As long as it's your home computer, do what you like and make your own best choices about security vs convenience. I for example would have a hard time setting UAC to the highest level, but I'm not gonna turn it off entirely because that's too much risk. If you want to set your own risk tolerance way higher that's on you but a) you should actually inform yourself about how much the risk changes and b) have a backup plan.

By design, Ransomware packages don't need UAC authorization. All they care about is encrypting documents accessible directly from the current user context, which aren't in UAC involved situations.

I've had UAC on max for years after learning of that particular design vulnerability. I don't find it particularly annoying, so meh. I do like how the Settings app can be super janky and pop up UAC prompts without much warning if you simply try to access some specific area of the app. Oh yeah and also I can't use Refresh in the app either because of UAC being set to strict, funnily enough.

Some applications are whitelisted by default, but it absolutely will trigger with all kinds of applications. Just keep using it for a while, you'll definitely notice. Also, of course, real-time protection needs to be enabled.

I have it on, because why not. But stupid stuff like not prompting if you want to save anyway like when you accidentally forgot to open notepad.exe as an admin. Or removing your network drives because it runs in a different context, therefore the installer you started that needs admin access, fails anyway. I know *why* it works as it does, but it's just shoddy IMHO. Like you said, it's been 10 years.

If you're doing something fullscreen like bideo james though you might get silent failures at any point Also it looks like they've changed it to include protected memory access too? That used to be a separate setting and that caused me problems with virtualisation (I couldn't install/update Intel's HAXM thing, just got unhelpful failures until I disabled that)

When I wrote that post I was mistakenly assuming that executables were being given a subset of permissions specific to their own folders, though it turns out I was just dealing with folders using nonstandard permissions. Things were working so I didn't delve any deeper than that, and as time went on everything I cared about moved to AppData anyways.
