Blogger Chris123NT is reporting that the LUAFV driver, which controls UAC in Vista, can cause latency issues if the controversial feature is disabled. Apparently, once UAC is disabled, a registry tweak that disables the driver in question also needs to be applied if the user wants to have solid boot times back (improved boot times obviously vary from machine to machine). The problem occurs in both Vista RTM and the current beta build of Vista SP1 (6001.17042). This seems to me like yet another reason why it’s not a good idea to disable UAC, but I'm sure UAC haters will have a very different perspective. It will be interesting to see how fast Microsoft will patch this problem, considering how important security is nowadays.

How slow can your vista boot? The 3 systems I use it boots in under 15 seconds to the login prompt from after POST (I dont count POST because that time varies by mfg and how they set it up)

I was talking about from login to desktop being all nice and smooth lol

Use this at your own risk, HDrive holds no responsibility if this tweak should cause your computer to spontaneously combust or eat your children.
1. Open the Registry Editor.
2. Navigate to "HKEY_LOCAL_MACHINESystemCurrentControlSetServicesluafv"
3. Double click the "start" string value, and set it to 4.
4. Reboot and see the improvement.
So there you have it. Test it and see how it works for you, of course your results may vary but it should render an improvement for the majority. Any questions or comments are always welcome.
Big thanks to Chris (chris123nt.com) and Ryan (bluescreenofdeath.org) for doing this testing and finding this out!

That line there, is the best way to find the people who think they know a lot about computers, but they have no idea what UAC is, much less how it works and what it actually does.
Right.. Fact is basically no application needs to run with admin rights, so while using programs that follow decade old MSDN multiuser guidelines you do not have an issue with UAC.
UAC is a simple enforcer of long standing guidelines for how programs should run under Windows. Any issues you have with it, are infact with your own usage of the operating systems or the programs you use.

it's so nice to hear sensible things like this from you, HawkMan, FusionOpz, I was getting SO ****ed off with all the vista previews and reviews totally mocking UAC, even actively promoting the idea of the 'solution' being to disable it, normally with no mention of the inevitable down side to doing so. And all of this coming from so-called professionals.
(that and complaining how it should ask for a password or it's useless, when it DOES when your not running as admin all the time, which they should not be doing.)
The only related thing I might consider worse has been software companies flat out saying 'disable UAC' in their forums/FAQ's for their solution to their own software shortcomings, again with no mention of how it's massively reducing the customers system security.
I don't like it. I know what I'm doing, I just don't need it. So.. maybe I should go back to XP?....

Yes you should
For the record, I like Vista after getting used to it, but yeah, no way was it ready when it was released. I don't care what any "Vista lover" says.

No software is ready when it's released. It's impossible to test something on every computer.

It sounds like you're either over administrating your computer and/or you have legacy software that requires admin access.
I'm curious, which is it? I don't encounter UAC dialogs that often so I want to find out why it's an issue with some people.
It's exactly the same as running a root 24/7 on Linux or OSX. No one does it because it's stupid. The same reasoning applies here. No security software can offer the same protection as the LUA principle.
For lots of people this is asking why people like coffee or not. It's purely opinion based upon knowledge for that specific person.

I thought everyone runs root 24/7 because its so easy and simple
Or, maybe, they just know what they are doing and really don't need it?

If they truly 'know what they are doing', they'd realize there is absolutely nothing they can do that offers the same protection against exploits that UAC does.
Actually, I do run root 24/7 and I have UAC disabled, and guess what? It all works perfectly!
If I have my doubts about an app, then I'm smart enough to run it in a sandbox or something.
Trust me, some people DO know how to handle computers, and keep them running nicely without the need to be bugged about every single change you make that could hurt your system but probably doesn't.
Remember the old DOS days? We ran about everything on our computers, there were no restrictions and somehow we managed not to mess up our computers. But maybe that's because there were far less computer users.

There was also no internet and the only way to get a virus was off a floppy disc from someone else.

UAC has saved my ass tonnes of times, especially when visiting pr0n sites.. like I would be doing my own thing and all of the sudden UAC comes on.. im like wtf! and then click "no" and say "**** you virus/worm, im not getting STD's"

lmao
god i lolled so hard
Or, maybe, they just know what they are doing and really don't need it?
No really, they do need it, and if they say not, they don't know as much about systems or security as they either think or claim they do.
Look at Linux, and OSX, see how few security problems they really genuinely have? now take a look at the account setup, oh yeah, that's it, you do not run as root 24/7, or in fact ever unless you absolutely have to to install or configure something.
For lots of people this is asking why people like coffee or not. It's purely opinion based upon knowledge for that specific person.
your logic is flawed. Next you'll tell us you don't need a seat belt when driving because "you know what you are doing"
Yeah. Right.
Yeah. Right.
With comments like that, who needs trolls? I wonder why I continue to browse this site.
UAC is not so much of a waste of time when you learn to silence the cancel/allow dialogs while still having UAC running to avoid running into issues with elevation, boot time, among other things.

yes I see Jacob gives me credit at the bottom of his "Full Story" link but jeez, you think he could link back to the original source?
j/k :p.
Awesome, that is pretty cool to steal someone elses discovery, copy and past instructions into your forum, and spin it off as your own. I see Chris beat me to posting, but that is really effed up....
I think it was you guys who just broke a story about Kotaku stealing photos and passing them off as there own? Hah, a bit ironic, no?
I may not have known about it but that testing was MY Work and i didnt get one bit of credit from Hdrive from it, Instead its directly plagerized on his website, then submitted here. Nicely done though, Jacob if your reading this, remove the post all together or SOURCE it correctly.
Then , you won't need to hack the registry...
Delete Prefetch folder
* Click Start
* Click Run (In case Run is not available as an option in your Start menu, you can make it appear, by following this procedure)
* Type Prefetch
* Click Ctrl+A (select all)
* Right click and select delete
* Close the Prefetch explorer.
By default, Windows Vista waits 30 seconds during the startup process before loading the operating system. You can safely decrease that time considerably, and thus speed up your PC boot time.
Here’s how you can do it:
* Click the Windows Start button
* Right click Computer
* Click Properties
* Click Advanced System settings
* In the Advanced Tab, Start and Recovery, click Settings
* In the Time to display operating systems list asetting, set a 3 second value instead of 30.
* Click Apply
Delete Prefetch folder

* Close the Prefetch explorer.
Great, someone still spreading misinformation about prefetch. If you think you know anything about how Windows works, get that idea out of your head right now.

That's secure, right?
I'm sorry, that's very rude and judgmental.
I have disabled UAC on many Vista machines and it does not make a difference from what I have noticed.
No, I didn't think so either.
No, I didn't think so either.
UAC isn't a AV program, but that doesn't mean it's not a "security package" either. So wtf is your problem?
So UAC hasn't helped much (except annoy users with boxes) - is my problem. Deal with it.

Maybe you should tell them not to automatically click Yes to the UAC prompt without reading what's going on.
That virus or spyware won't run if you have UAC block it from the start.
The fact average users don't know what they're clicking yes to and get infected doesn't mean UAC doesn't do it's job.
UAC is tied into alot of services. Performance tuning, and Software compatability to name a few. LiL drunk at time of post fyi.
I do wish Microsoft made the services system more intelligent. By default all Windows versions have had way too many unnecessary services on automatic startup. This makes the startup/shutdown really slow. Some sort of system that really checks if you need all that crap would be good.
When i first used Vista, i thought a similar way to you, i'm experienced, i know what it all does, i can turn off UAC, i was wrong, within a few days i had managed to install some Adware without realising it. UAC is now back on and i don't really see it that much, only when i install a new program or run an old program which wasn't designed for Vista.
Each one to his own, nothing wrong with keeping it enabled or disabled.

What happens in the future when one of your apps that you seem to trust fully as being secure is found out to have a nice security bug that lets people take over your system?
It's not like it hasen't happend before you know. Quicktime? Hell even Norton AV had that problem. And there are others out there.
So, again, how do you know or realise if some "trusted" app you've been using all this time with UAC off (because you kept getting prompts when you use it or others), isn't hacked and being used to do something else on your system?
UAC isn't meant to stop you from installing adware or spyware only. You do realise this right? I mean, hell, you're a PC expert.

I emphasized on adware since that was the point of the poster.
I update every software on my PC on the same day of the update/patch release, sure a hole can be published before a patch is out, but heck, common sense plays a pretty big part in this. I didn't ever face any problem with this philosophy for 10+ years, and well, I'm not running a CIA server to tighten the security so I had to get a prompt in my face each time I want to delete a folder.
As I said, each one to his own, apparently it's too hard to understand to some people who support UAC as it's the next big thing, although a computer n00b will click "Allow" to allow a spyware/virus/attack etc to be executed (I see it happen). It's like people who advise to set a black/dark wallpaper to lengthen the lifespan of a monitor, silly
Of course, that may be because I had it installed for only 2 days because I saw how bad Vista sucked!!
Now,
I have a new system with Vista installed and still can't stand it, but I paid for it this time, so may as well keep it, maybe! Am still considering blowing this POS OS off the computer though.
This UAC thing had got to be about the dumbest "security" feature ever thought up! Took me about 5 minutes of setting up that new computer to see how stupid this is and then disable it!!

I can run old games just fine without being administrator. What games really require you to be an administrator? Any game that puts its save files in My Documents or the Saved Games folder doesn't need admin access. If it IS a game that puts save files in the Program Files folder, just install it outside of the main Program Files folder or on another drive.
I play lot of old CNC games mostly, and they all run perfectly without admin access.
You could get around it by installing into directories other than Program Files, but then you run the risk of mods failing to install or just not work right. Admittedly, this isn't a Microsoft or Vista shortcoming but sloppy coding on the part of the software writers. The common denominator though when things get weird is frequently UAC and the choice becomes either work around everything else, discard the software, or simply disable UAC. I chose the latter.
I have about 100 games that I revisit occasionally, and some date back to 1992. Heh, one game Civilization 2, won't play the game music unless an analog cable connects the cdrom to the cdrom sound input of the soundcard. That has nothing to do with UAC or Vista, just thought it was interesting trivia to show how some things were coded very rigidly.
Another thing that happened with UAC was I installed a program and it installed into the Program Files directory, but it never prompted me. I think it was 7-zip, but could be mistaken on that. Anyway, it was a program that also integrated into the Explorer shell as a right click option. When it installed and UAC never popped up the first thing I though was "OK, not only is it annoying but I can't trust it either" It let this program install without me having to run it as Administrator and never even blinked. To me UAC is at best a False sense of security, and at worst an over engineered added layer of complexity.
condoms suck.... so does UAC!
There are a truly awful lot of 'unexpected' but well cared for children, single mothers, unwanted children, orphans, shotgun weddings, and STD's all around the world simply because a lot of people sadly really are THAT STUPID, and stupidity often increases exponentially with arousal and hormones.
When I choose to use Vista, UAC will be the first to go.
Oh, and no. I haven't had spyware OR viruses for years. (including protection for both - so don't bother with the comment.)
Even for those that don't you can automatically run poorly coded applications as an elevated process.

MikTex seems to have problems with it, as on demand missing packages need to be installed from the command line window. Somehow the processes are started in a way so that UAC makes problems. (even when the command window is started with admin rights)
I've been working in IT for.. er... 10+ years, and been enthusiastic about IT for a lot longer than that (BBC Micro's, Acorn Archimedes's, etc) - I think I know what is an acceptable risk and what is potentially harmful for my computer. Its no worse than it is under XP and i've yet to run into any problems with software installing itself without my consent?
Ugh. Just shoo.. shoo, all of you.

Right on bro. Its one of the weirdest things. UAC is a catch all for MS(they hate it when you say that too) I didn't need it yesterday and I don't need it today. My system is as locked down as I want it and I will never allow UAC to run on any system I own.. EVER! So stick it.
I mean really people? Does that not set off sirens in your head about where Vista is as an operating system? I like Vista but it needed another 12-18 months to cook and these UAC growing pains only serve to hammer home that obvious point.
VMWare?
Strikes me that if you really "need" this "feature", then you're a bit of a n00b.

Seriously, it's not just a "Are you sure?" permission asker. It provides file and registry virtualization and internet explorer 7 runs in protected mode when it's on. Also it enables User Interface Privilege Isolation, which combats code injection exploits.
I recommend you to enable it, but put it on quite mode, you dont even notice it.
Windows Vista for Many Users
Windows Vista for Single Users
So when I install vista, it gets one name, all rights to me, no admin questions asked.
Its your choice to disable... I've been running Vista for quite a while now, the first thing I did was disable UAC.. had NO problems since.
If its such a problem, tell me why?
