I swear, it seems like people are okay with the idea of everyone BUT Microsoft have access to all their personal information on their PCs. Why would anyone install software that has this kind of recklessness in the official documentation?
After making modifications, the exclusion can be deleted if desired. If you have more info about risks of using the dwt utility, I'd be real interested to hear about it.
As for the virus checker, their program's raison d'etre is making registry changes. It's not difficult to imagine that being flagged by Windows Defender is unavoidable.
But that's not really the thrust of the point. It's software from an unknown provenance, and yes, that's pretty standard for Windows but it's not great and it's getting worse all the time. Virus scanners are not a great solution, but not having them are worse. Without any kind of a checksum on that page, it's impossible to verify that the binary you have is the one that you should have. (Not that it's guaranteed that you can do so if there is a checksum.) So you're already in a bad situation, and you're turning off one of the few safeguards you have.
As for registry changes getting flagged by Defender... programs that change the registry aren't rare.[2] They do not universally share this problem. I imagine it's probably a false positive and I don't know how it could be avoided, but the proposed remedy is reckless.

As I said elsewhere, I'd love to be *nix only but my gaming preferences will not allow it.
There are some utilities available that are supposed to improve the privacy/security of Win10 installations, e.g., [0].
My wife kept asking me if she should upgrade to Win10 and I said "don't do it". Since Win8.1 will be supported until 2023 or so, it really didn't matter. Now, thankfully, the "free upgrade" period is over and she won't be nagged to do the upgrade.
After all the years in the game, we'd think MS should know better than pulling all this crap on its users.
