OK partly I will answer myself, although I still do not know how to solve the problem to the end.
I sought by the record is in the case of my test computer in the key:
I see the key in regedit, unfortunately I do not see him in PowerShell
Get-ChildItem HKU:\ | Select-Object Name
Get-ChildItem : Cannot find drive. A drive with the name 'HKU' does not exist.
At line:1 char:1
+ Get-ChildItem HKU:\ | Select-Object Name
+ CategoryInfo : ObjectNotFound: (HKU:String) [Get-ChildItem], DriveNotFoundException
+ FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand
Does any of you know why?
