Delete LEGACY_.... keys in Registry ?

[SuRGV]

Hi,
I installed Oracle (9i) and then removed it. Now I want to install again but it did not allow me to use certain name for database name because it says that name already exists.
After searching through Registry, I've found 3 keys that I can't delete:
-LEGACY_ORACLESERVICEDESC495
-LEGACY_ORACLESERVICED495
-LEGACY_ORACLEORAHOME90TNSLISTENER

Is there any way to remove these keys (as well as other LEGACY_... keys) ??

I'm using Windows XP Pro.
Thanks.

LEGACY keys cannot be (easily) deleted. They are created everytime a service starts at bootup. One for the current profile and typically one set created for LKGC. If you remove the services and reboot you SHOULD be able to recreate those databases. If by some chance you can't, there is one other thing you can try:

1) Start -> Run: regedt32 -> OK (make sure you are logged on as an administrator)

2) Go to the HKLM sub-window and find the key you want deleted. Highlight it.

3) In the Regedt32 window menu select Security -> Permissions.

4) Change the access permissions for Everyone and/or Administrators to Full Control. Apply the settings.

5) Repeat 1-4 for all keys you need deleted.

6)Close Regedt32 and open Regedit. Delete the keys you don't want anymore.

Unlike files, the administrator does not have automatic full control over the registry. There are certain keys that only SYSTEM can touch unless an admin changes the permissions.

EDIT: One minor correction, caught by Greebe. Windows XP has finally killed Regedt32. The permissions settings are in Regedit, under Edit -> Permissions. Do the same steps, but do it all in Regedit. The above works for Win2k and below.

Windows XP has finally killed Regedt32.

The vileness never ends..
