Where can I get free Microsoft point codes to redeem without having to pay for other things to get that for free
No where it doesn't work that way with digital money
There is no way you can get free Microsoft points; you'll have to do something to get them. You will be required to do something like take a survey or send a certain link to a certain number of people. Check out www.mspointscodes.com/ and www.prlog.org/10465310-free-microsoft-points-codes.html for some things you can do to get free points.
Go to bing.com. They have a rewards program. You can get Microsoft points and more stuff but it takes about a week to get at least 100 Microsoft points.
