The Windows 10 Creators update seems to have hosed Apache\'s httpd service, which now errors when I first start the WampServer.
The official form confirms this suspicion
Update: looks like the 3.0.8 patch resolves the issues with WampServer 3.0.6 and the Windows 10 Creators Update.
It's not well publicized on the website, (you need to click the SourceForge link on the website and navigate the folder structure to find it.) Direct link to the update here:

Update: looks like 3.0.8 has been pulled as 3.0.9 just came out; here's the link to 3.0.9: https://downloads.sourceforge.net/project/wampserver/WampServer%203/WampServer%203.0.0/Updates/wampserver3_x86_x64_update3.0.9.exe?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fwampserver%2Ffiles%2FWampServer%25203%2FWampServer%25203.0.0%2FUpdates%2F&ts=1498418727&use_mirror=pilotfiber
