OldFatGuy: Thanks. Unfortunately, most of them returned after a reboot.
And now for some fun facts for those of us clueless ones who hope and pray when we find info on something we need and how it's so hard to tell what's "good" advice and what's bad.
Case in Point: One program I was wondering about uninstalling is MSI SDK.
Now here's what one website about it:
MSI stands for Microsoft Installer, which is a tool used to install programs on Windows computers. The MSI SDK is a set of tools and resources that allow developers to create and customize MSI packages for their software.

Okay, so it's a Microsoft product. But wait:
If you are a software developer, you may be wondering if you need the MSI Software Development Kit (SDK).
The main executable file in the MSI SDK is MSI.CentralServer.exe, which is 167.98 KB (166896 bytes) in size on the computer. To remove the MSI SDK, type C:/Program Files (x86)/MSI/One Dragon Center/unins000.exe into the Start menu of Windows.

Okay, so it's an MSI product (Dragon Center is 100% verified to be an MSI Product).
This is so much fun for morons like me. So it either stands for Microsoft Installer or MSI Software Development Kit. I guess I'll throw my lot in with MSI Software Development Kit since, you know, MSI SDK is pretty much an exact match.
And I still can't find any good recommendation on whether or not to keep Dragon Center (or the newer version which is called MSI Center).
From the description you found, you only need the msi-sdk if you are going to develop programs and setup msi installers for them. I sort of doubt you are, so it should be safe to uninstall msi-sdk.
