This applies to Windows 7 SP1 x64 Professional.
If UAC is set active, WWL will not start up automatically when the system is rebooted. This may be happening on other Windows versions also.
I do not know if this just started with V7.0.96 because I typically do not have UAC active. I was testing something else by activating UAC and discovered that WWL will not start up with UAC active.
I am not sure if this is the same problem I had but sounds the same. I used Revo Uninstaller to uninstall it and reinstalled it and that worked for me. You can try that and see what happens.
I found that the Privilege Level on file ww.exe was set to “Run as Administrator” active. By unchecking this, WWL now starts with UAC turned on or off.
