After installation of windows update on 10th February 2016, the azure roles are not starting in emulator (Full/Express). The logs show below

Looks like if i use full IIS (not IIS Express) and Full Emulator it works but if i select Express emulator (i can only select IISExpress) it does not*

Uninstalling Windows Update KB3126593 solved the problem, but after the Windows update of patch day April 12th 2016, the emulator did not start again. By successively uninstalling the updates, I identified KB3147071 to be the culprit. I reinstalled all the other updates and excluded KB3147071 from further updates and now the emulator works again.

As I have run into the same issue, I tried to uninstall the updates one by one and came down to the one causing the issue: KB3126593.
To verify, I installed all the updates again, except this one, emulator still started properly. After installing the problematic one, emulator stopped working, resumed after uninstalling it again.
I am using quite old Azure Tools v2.6, maybe this is fixed for the newer versions, cannot try this for myself unfortunately.
On my side, both Full and Express emulators were failing, both tried with IIS Express (not using full IIS).
Hope this helps!
Update 18 Feb 2016
I tried to contact Microsoft Azure Support to report this problem, also leading them to this StackOverflow question for more detailed information. They did not seem to care so much, because I don't have an appropriate paid support plan (quite frustrating). If there is anyone who would report this with a valid support plan, I am free to provide any info needed.
Update 22 Feb 2016
Microsoft Azure Support finally started to solve it, it has been reproduced and dispatched to the production team! The only workaround they presented is to use Full IIS in the meantime.

I use Azure 2.7 and ran into the same problem. After uninstalling Windows Update KB3126593 it worked. In the post-installation information section of that update, Microsoft mentions certain error messages that might show up in the event log. I installed the fix again and tried to start a worker (which failed of course), but I did not see any of the described messages. Then I added the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Safe Load Prefixes with the value 'C:\'. However, I still could not launch the worker role. So I uninstalled the update again and then launching worked. Just to share my experience with my attempt of having both: the Windows update and a working compute emulator.
