I've heard about Prey but haven't actually tried it myself. They have a free tier to do basic tracking and a paid tier for extra features (like remote wipe, etc). See https://preyproject.com. However, I'd be concerned about the security of an application like that.
The real issue is that PCs don't (usually) have automatic 24/7 connectivity via a cellular network. Without this, if someone steals your laptop and never brings it online, how would it report its location? Or, if you're using normal software installed on the hard drive, the person who stole it may never boot your OS and could just wipe the drive, rendering most normal software useless.
EDIT: Oh yeah, if you use Windows 10 and login via a Microsoft account, you can check on the last known locations of devices at account.microsoft.com.
