This sounds like Apache has not started.
There are a number of reasons this can happen all of which normally mean that something else is using TCP Port 80.
As its windows 10 you are using it is likely to be either SKYPE or IIS.
Windows 10 installs IIS (MS's WebServer) by default (for reasons only known to MS) If you are not using it I suggest you uninstall it as it is not required for normal operation of Windows.
So go to Start -> Control Panel -> Programs and Features
Click the 'Turn windows features on and off' link in the left hand menu.
Wait for the list to load and then find 'Internet Information Services'
Un check the check boxes for the following items ( you may not see all of them ), and there may be others I done know about. You may have all of these or just some of these.
1. IIS
2. Web Deploy 2.0 (Web Deployment Agent Service)
3. MS Sql Server Reporting service.
4. BranchCache ( Windows 8.1 )
5. SQL Server VSS Writer
Windows will then have a think for a while and then remove those applications, you will probably be asked to reboot to complete the uninstalls.
Reboot anyway when the uninstalls are complete.
Then try wamp again.
Alternativeley just disable it/them.
Start -> Control Panel -> Administrative Tools -> Services
Find IIS in the list of services.
Left Click that line and select Properties
Change the 'Startup Type' to disabled.
Ditto for the other possibilities if you see them.
