It looks like a new platform for all MSI functions, not unlike Dragon Center, but does not come with any of Dragon Center's bloatware modules installed.
I thought MSI Center would just be a reskin of Dragon Center, but that doesn't seem to be the case. I can't believe I'm saying this about MSI, but this is an improvement.
I suppose that time is now, though the Microsoft Store indicates that it was originally published there 11/12/20. They announced MSI Center during CES 2021 as a replacement to Dragon Center, but I do not believe they mentioned a release date.
