Registry permission problem

[wreckwriter]

I switched from Nvidia video card to ATI and am having trouble getting
rid of the Nvidia startup stuff. The files are gone but there are 3 reg
keys I can't get rid of. All are in
HKLM/software/microsoft/windows/current version/run Keys are Nwiz,
NvCplDaemon, and Nvmediacenter. I can open regedit, delete them, close
regedit, and when I reopen it they are back. My user is a member of
administrators and regedit show administrators having full control.
Have also tried from administrator account and from safe mode. As
administrator I can delete the keys and close/reopen regedit and they
still gone but no matter what I do the keys come back on next reboot.

Have also tried DriverCleaner Registry cleaner, and JV16 power tools,
same result.

I've tried checking permissions all the way up the tree and everything
looks ok; obviously it isn't though. This has to be a permissions issue
but I can't find it.

But the files are all gone, its giving error messages at start.

Note- disabling them in MSCONFIG also does not hold, they come back.

Then as David said something is putting them there. Uninstalling the NVidia
drivers didn't do a complete job. You'll have to track down the offending
files manually. They are most likely in the windows\system32 folder and most
likely a dll file. I've never tried it but this program may help.

I used that initially, it claims everything is gone.

It is almost certainly not a permissions issue. You must have a program running at start (or one of those mentioned programs writing at shutdown) writing them back.

 

[wreckwriter]

Neither of those files exist and no service starting with nv is running.

 

[David Candy]

They don't come back by themselves. Somethingf has to write them. Why do you think these are the only NVidia files.

The you'll have to manually search the files for nvidia files. Hovering the
mouse cursor over a file in explorer will give you a popup with the file
details for most dll files. You could also search the registry for nvidia.

I've deleted every nvidia file. Back to permission problem I think.

 

[Kerry Brown]

I've deleted every nvidia file. Back to permission problem I think.

If it was a permission problem you would get an error immediately when
trying to delete the keys.

Just a thought. Do you have any anti-spyware/malware/virus apps running that
may be disallowing the changes?

 

[David Candy]

It has nothing to do with permissions.
