Windows Live Sync – WLSYNC.EXE
Files called wlsync.exe and moe.exe install with WindowsLive Sync. Moe.exe (Mesh Operating Environment) and wlsync.exe (Windows Live SYnc) make up the core syncing engine for the new Windows Live Sync, as well as the older 'Live Mesh' that it replaces. The new Live Sync is based on Mesh technology, and still includes the same syncing engine. Windows Live Sync lets you synchronize folders between your computers and online storage at SkyDrive. You'll find more information at http://explore.live.com/windows-live-mesh-devices-sync-upgrade-ui If you do not use Live Sync, you may have these files installed on your system if you installed the new Windows Live Essentials bundle.
