It's been like this for a long time. Same as with video card drivers. I assume Microsoft gets a request from the manufacturers and then they just put it out there. When it happened to me I checked "hide this update" and it never showed up again (same as I do with video driver updates). So I don't know if it will actually replace a custom profile made by a calibrator. But this is not good:
This profile was set active, overriding the Windows default that was previously set.
For the past year or two I've only used monitors from Dell and Eizo, and never seen any profiles from either. So it's probably just a few manufacturers.
So, Noel, what you are saying is that, when one opened Advanced tab in Win7 Color Management the System Default has been changed from sRGB to something else?
I've been thinking about that setting, in that the default sRGB and my calibrated one (on my new Dell) don't agree, but they are close. My first impulse was to select the calibrated. But I left it for the moment.
While I'm at it, "Viewing conditions profile" throws me. I haven't run a Google search on that term but I think if I am playing with these choices, I should know one or two things about them.
No, actually the System Default stayed the same, but the ACER profile showed up in the Devices panel. However, [ ] Use My Settings was NOT checked, implying they found some way to install the profile that's outside the normal configuration settings somewhere between the Advanced and Devices level configuration.
The fix is to check the [ ] Use My Settings box, add the profile one wants to use in the Devices panel, and [Set as Default Profile]. This overrides the setting above.
That is weird! It also makes me feel nervous.
That is where my i1 profiles show up and to think MS can simply add a profile to which the monitor responds in that menu w/o Use My Settings checked falsifies the security of that setting.
I had better revisit my Update settings.
