This small example is done in Windohs native scripting (abomination
is better term) known as Visual Basic Script:
' ////////////////////////////////////////////////////////////////////
' FileName: DemoRmoveKey.vbs
' ////////////////////////////////////////////////////////////////////
Sub RemoveKey(gcsKeyToDelete)' removes passed registry key
Dim oShell
Set oShell = CreateObject("Wscript.Shell")
On Error Resume Next
oShell.RegDelete gcsKeyToDelete
If Err.Number Then
MsgBox "Error # " & CStr(Err.Number) & " " & Err.Description
Else
MsgBox "Removed registry key", vbInformation, gcsKeyToDelete
End If
End Sub
' Uncomment next line and kiss your ORACLE registry key good bye:
'CONST sKeyToRemove = "HKLM\SOFTWARE\ORACLE\"
' But this is OK to try since there is no such key in your registry,
' make it manually and see what happens:
CONST sKeyToRemove =
"HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\XYZ\"
RemoveKey sKeyToRemove
While removing known registy key is trivial, enumerating registry keys
is not. You'd need to be familiar with another horrid object model - the
notorious WMI to pull trick like this (straight from note 124353.1):
3.g. Go to HKEY_CLASSES_ROOT, remove all keys that begin with
Ora or ORCL (e.g. Oracle..., ORADC..., ORAMMC..., OraOLE...,
OraPerf... and ORCL...).
For kinky details on WMI have a look at:

wmi_start_page.asp
Another place to have a look at since you can get some working examples:

Forgetting about Winodohs natives, move to wonderful world of
Python or Perl and be able to do more magic with lesser amount
of effort and far less headaches...
