Sadly, as of today LogMeIn is no longer free so many people will now be looking for an alternative way to manage remote PCs for free. Here are a couple of free alternatives to LogMeIn:
- TeamViewer – works exactly like Logmein to manage remote PCs
- RDP (You could open RDP ports to the internet and use Dynamic DNS or a static IP) – Not recommended for security reasons
Of the above free alternatives to LogMeIn, I recommend TeamViewer. It has the best features and is very reliable and reasonably secure. Failing that, the next best alternative might be VNC.
