No administrator access after installing QWT on Windows HVM

R4.1 QWT built using the community repo guide.
I don’t get a UAC or admin prompt at all after install QWT.
I can run .exe’s but I cannot do any administrative stuff.
I only get “access denied” in various forms.
If I try to launch a command prompt or powershell as admin it only opens it as my logged in user.

I am running Windows 10 AME, without spyware and a restricted user account. There is no administrator account enabled by default on this install. I haven’t enabled it before installing QWT.
