To enumerate all subkeys in a Registry key, you might be using a line like this:
PS> Dir HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall | Select-Object -expand PSPath Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Uninstall\AddressBook Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Uninstall\Connection Manager (...)
It will return the PowerShell-style path including the provider name, not just the Registry path. If you used the -Name parameter, on the other hand, you just get the subkey names and no path at all:
PS> Dir HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall -Name AddressBook Connection Manager (...)
The easiest way to get the true Registry path is Resolve-Path:
PS> Resolve-Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* Path ---- HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AddressBook HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Connection Manager (...)
The resulting paths still use PowerShell drives. To get the native Registry paths, try this:
PS> Resolve-Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object -ExpandProperty ProviderPath HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AddressBook HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Connection Manager (...)
