registrykey

I am working on File Associations. I have identified that there is a key called UserChoice in: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\[ext]. I have been able to read from and write to the UserChoice key provided that I create it and that it has not already been created by Windows. However, if the UserChoice key has already been created by Windows, then I need to run as Administrator to get access to the key. My ultimate goal is to delete the UserChoice key.

So far I have used Get-ItemProperty and reg query and although both will pull the value, both also add extra text.

Andy Arismendi $key = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion' (Get-ItemProperty -Path $key -Name ProgramFilesDir).ProgramFilesDir I've never liked how this was
