It sounds to me like Windows Update is replacing the driver you're installing with a Microsoft NVIDIA driver, and apparently it's a bad driver. So, watch for this update and hide it. Don't let Windows Update install updates automatically for now.

If you don't have the ability to do this, then use this: https://support.microsoft.com/en-us/kb/3073930

Here's the direct download of the tool in the article above: http://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

This should give you the ability to hide updates that you no longer want, such as all driver updates.

I mean it is too big and confusing and adding small options like this would make it more confusing unless I hide them behind tabs.

Hi Ian - are you using the newer version (v4)? It should not have this issue.
We have not updated everyone yet, so you can try downloading again at https://justgetflux.com/

If you are on v4 already, I will look into it...

@herf It is better ! "Current" adds some understanding.

Think about naming these two concepts. "Effects" is good. Add the concept definitions there, nearby.

It doesn't matter how big or small the program is, appdata is not for executables, period!
If every developer used this logic "my app is so small, no reason ask user were to install it" the PC would turn into smart phone clone (although it seems windows is heading that way anyway)

How many Windows users out there that don't have admin privileges on their Windows PC? Perhaps by providing ability change installation directory it would allow install by non-admin and receive updates by non-admins. Or better yet - a portable version would kill 3 birds with one stone...

Regarding updates, there are two different approaches in software updates:

update notification with provided ability to install forced update

A good software would use #1 and allow user choice if they want update or not (and perhaps even allow them chose if app should remember their choice in next update). Many users don't like fresh updates, because often it bring more problems and they want to see other users responses first.
f.lux unfortunately chosen #2, doing it without user's consent, opening a door for installing whatever it wants without user's knowledge, sorry, but that's exactly how backdoor trojans work...
"You simply cannot convince millions of people to update by hand, it doesn't work." that's precisely why #2 approach is bad, because a lot of people disable auto updates that happen without their knowledge and now have to update it manually.

[EDIT]
And f.lux team being an asshole, by giving negative reputation to posts they don't like, while we, mortals, can only give positive reputation...

Thank you! I'll look forward to its return then.

The beta version I posted yesterday says "Adjust day and night colors together..."

It will need an editing pass to reduce the word count, but I'm trying to fix it. :)

@herf In general ! I haven't tried f.lux as of yet! Please include Text-size customizations within f.lux interface so that one could tinker with Font-settings for entire Win OS. How do you make your Desktop items appear in Bold text size? Pl reveal ?

it already does, right click the flux icon > disable > for full-screen app

You're welcome! This program was shown to me right here on the f.lux forum too.

Oh, and I know this may not be necessary, but I apologize for not providing a convenient link to the program. I didn't want my post to look like spam or some official advertisement. I've learned it's good to be more careful than usual on this forum.

@herf Already using the beta. I just feel the curve is too steep.

Hi - we prevent sleep if you turn on Philips Hue support, currently.

@herf I'm not very computer savvy but according to my driver updating software "Driver Easy" all my drivers are up to date.

I think it'll work well since you're allowing yourself at least 3 hours to unwind before going to sleep.

ooohh, I see :)

thanks for clearing that up, I suspected that was the case but couldn't remember if soft white was there before or not.
