The Razer Stargazer is a SR300-compatible camera that uses the same drivers as Intel's own SR300. So this means that it would be susceptible to changes in the SR300 drivers.
The driver system for the SR300 was recently changed so that the DCM software is no longer required for SR300 cameras. Instead, the drivers are now part of Windows 10 itself in the latest versions of it.
This process is new enough that I do not yet have full information about its workings. So I will link Intel support staff member Jesus G - the_jesus - into this conversation to get his input, as he knows about the new process. Thanks for your patience.
Shame the new drivers don't work
I have a really nice looking monitor decoration but no working camera
Oh, and the drivers distributed with windows update (22.214.171.124) for the USB device "Intel;RealSense Camera SR300" actually remove the Depth and RGB image devices from device manager and then revert back to a Microsoft driver from 2006 :/
At this point all I can do is restart and re-install the DCM software to get the device back (of course it doesn't work)
Jesus G has advised me to point the affected folk to this page, saying that the information here is the appropriate answer to the update problems for the time being.
I did work around. Shame Intel, Windows and Razer dev team.
1st. Go to Device Manager.
2nd. Go to Imagining Devices:
Right click - Intel(R) RealSense (TM) Camera SR300 Depth - delete with uninstall checkbox.
Right click - Intel(R) RealSense (TM) Camera SR300 RGB - uninstall.
Important: Don't restart PC yet till you deleted both.
If system ask to restart click No, and delete secondary driver and select Yes, if both deleted.
3rd. Restart PC
4th. Auto plug and play detect.
5th. Restart PC
6th. Try install intel_rs_dcm_sr300_126.96.36.19918.exe - if succesful go step 7th, if no go step 2nd, and continue.
7th. Checked version of installed drivers..
If version and date are same as mine ur home baby, if not keep uninstalling drivers from device manager, but don't reinstall DCM - just skip that point. My Date and Version showed correct after few reapets of all steps:
