The Creators Update has caused issues with cameras - not just Intel RealSense but with Logitech models of webcams too. Someone else had a problem with the camera on their HP Envy 17 stopping working this week, and they had it fixed by contacting a Microsoft support representative. See the comment at the very bottom of the page in this link:
The Microsoft representative fixed it through opening a remote control link to the user's PC and installing files for them. But you could probably do the job yourself using the process described in the comment if you are experienced enough with PC installations.

Thanks for reaching out!
I understand your situation and how it can be inconvenient. It has been officially noted that the Windows* 10 Creators Update build 15063 is not compatible with the Intel® RealSense™ SR300 camera driver as you can see at https://communities.intel.com/community/tech/realsense/blog/2017/04/07/windows-10-creators-update-build-15063-is-not-compatible-with-intel-realsense-sr300-camera-driver.
As it is stated in the article above, we are working on the issue but as an immediate workaround, we suggest not to install Windows* 10 Creators Update build 15063 through Windows Update.
I hope this information helps you,
