Registry-based issues with IOBit

[AgentParadox]

So I got a bunch of IOBit products, hoping they would do what I wanted them to. They didn't, and even though I (attempted) to uninstall them, they changed my registries, hooking onto the default Windows Uninstaller, and disabling Windows Defender, therefore I couldn't. How would I go about changing them back to the default settings?

P.S. I'm new to the forum, and vBulletin. Apologies if this is the wrong subforum, I did not see a problem-report subforum for the entire IOBit suite.

Am I left in the dark or something?

You provide no details of what you did and what happened, so it's impossible for anyone to give you a reply. "A bunch of IOBit products" is not helpful. Have you tried using System Restore within Windows?
