.SYNOPSIS
Mount a windows registry file
 
.DESCRIPTION
Mount a windows registry file like user.dat, SYSTEM or SOFTWARE from offline windows disk, or even BCD file.
By default, content of this registry is mounted under HKLM:\{Generated GUID} registry key.
 
.PARAMETER File
Full path to a windows registry file. Must be used alone.
 
.PARAMETER Path
Full path to an offline windows installation folder. Must be used with -Hive parameter.
 
.PARAMETER Hive
Name of a windows hive. Currently, only SOFTWARE and SYSTEM are supported. Must be used with -Path parameter
 
.PARAMETER MountPoint
Override default HKLM:\$GUID MountPoint by explicitly specifying MountPoint. Must be full registry path e.g. "HKLM:\Some_Path"
 
.EXAMPLE
Mount-OfflineWindowsRegistry -Path E:\Windows -Hive SOFTWARE
This example will mount HKLM\SOFTWARE registry hive from an offline windows disk connected as E:
 
.EXAMPLE
Mount-OfflineWindowsRegistry -File E:\Users\<username>\user.dat
This example will mount a user profile from the same offline windows disk
 
.OUTPUTS
Registry path to where the registry file is mounted
