Before the AnchorService fix (installer = master da948e5f + the #883 Get-Acl/@(if) patch only):
  Windows PowerShell 5.1.19041.6456:  22 passed, 1 failed
    FAIL: re-apply: 7 steps, all unchanged (AnchorService=changed,PeCacheDir=unchanged,PeEntriesDir=unchanged,WorkerFolderAcl=unchanged,
          InstallRootDeny=unchanged,FirewallBlockOutbound=unchanged,HostServiceEnv=unchanged)

After the fix (Invoke-OtOpcUaSc builds the sc.exe command line explicitly):
  Windows PowerShell 5.1.19041.6456:  24 passed, 0 failed
  PowerShell 7.6.10 (Core):           24 passed, 0 failed
Each run: -WhatIf (changes nothing), apply (7 steps changed), re-apply (7 steps unchanged), uninstall (6 steps changed),
second uninstall (6 steps unchanged); anchor Disabled + SID + quoted binPath, ACEs, firewall rule, host-service env, all removed again.
