install report (windows): conflict with dkml

[emillon]

Hi,

I have the following experience to report on windows. I installed opam 2.2.0~beta3 from winget, but it's conflicting with a previous forgotten dkml install. Here are my interactions:

• install works well (though I'm initially confused by the diskuv.opam name and the dkml url)
• opam init says it cannot configure cmd, and then exits without doing anything. I suppose cmd is not supported, and retry with powershell. same thing.
• I discover that there's nothing to do in opam init, because there's already an opam root
• I delete opamroot with Remove-Item
• now opam init works, but detects the ocamlc 4.14.0 from dkml 2.0.2 and uses it as a system switch
• I try to run the uninstaller from dkml, but it doesn't work
• I remove dkml from AppData "by hand"
• now I can create a non-system default switch

I'm not sure what to fix / if there's anything to fix, but this might come up again in the future so I figured I'd open this. Thanks
