Remote Desktop recurring use

Hi all.
I am currently using TeamViewer to help my family with their semi-regular computer needs. Regular enough, I suppose, that TeamViewer detected 'commercial use' (even though mostly what I do is install drivers and updates on my family members' computers.
I cannot justify 58$ a month for TeamViewer. So, my question is can I setup Windows' Remote Desktop for recurring use?
I have googled this and searched forums and articles, but have not found a satisfactory answer.
If anyone has experience with Remote Desktop's updated futures, please weigh in.

Surprising! How do you know that ? Were you running 'Commercial Trial' version ? Try to Use 'TeamViewer QuickSupport' & 'TeamViewer Portable' from Down There!

There have been multiple reports of TeamViewer harassing customers about suspected commercial use in an attempt to get them to pay for a monthly subscription.
@FUState, check out VNC remote desktop:
TightVNC: VNC-Compatible Free Remote Control / Remote Desktop Software

I received a message in response to my support message to TeamViewer (in my message I explained how I am using TV for personal use (with details)).

They responded with apologies and an explanation (essentially saying) that they are cracking down on suspected commercial users (though they did not get into details of how they suspect commercial use).

So, I can use TeamViewer for free again. I appreciate all of your suggestions, and if this happens again I will definitely look into the other options listed here.

Thank you!
