Remove a Registry Key

abos_systemax

The RegKey works perfect in Windows, it appears that the REGED program in FogOS is the one having issues with the notation.
I was looking for any documentation on the subject, but Google refuses to think that I really do not wish results for REGEDIT, but for REGED.

That is why I wanted to boot to FogOS without actually deploying an image, so I could actually try to find a manual for REGED

@abos_systemax OHH, okay, I get you! sorry for the misunderstanding there.

I don’t have any experience with this yet, but I will get to ~~playing~~ “working” and see if I can’t figure something out in my free time!

Hello everybody,

I made a .bat file to delete a registry key.
I use it in a snappin with Batch Script but it does not work, I have an error code 1

reg delete "HKLM\SOFTWARE\TightVNC" /f

Someone can help me please ?!

Thanks you

Tom Elliott

@maouu Does the key actually exist on the machine?

The error code you received is from the reg delete command itself. If the command runs it only returns two codes.

0 = Success
1 = Failure

There isn’t any information as to why there would be an error so I’m just guessing the key simply doesn’t exist on the machine the snapin is running on.

maouu

Yes the key exist !
Does FOG have system rights to delete a registry key?

How can I use the .reg file to delete the key ?!

Thanks

Tom Elliott

@maouu The FOG Client runs as the SYSTEM user, so yes, it has systems rights to delete a registry key, I would think.

Are you sure that is the location of the key, or is it in HKLM\SOFTWARE\WOW6432Node\TightVNC

I’m not questioning your expertise, but the information would seem to indicate something else.

I suppose you could create the reg, create a batch script to load/run the reg key, and use a “snapinpack” to run on the machine.

There’s too many things to think about here though.

@maouu said in Remove a Registry Key:

How can I use the .reg file to delete the key ?!

regedit.exe /s "mykey.reg"

Then in your mykey.reg file you need this syntax with all of the other normal prefix settings

[-HKEY_LOCAL_MACHINE\SOFTWARE\TightVNC]

Also know that the short name hklm may not be what reg is looking for, you may need the full name there. I have not tried it only offering a suggestion. The FOG Client/snapins run as SYSTEM so it should have full access to the registry even with UAC enabled.

Oh yeah, depending on what version of VNC is installed (32 or 64 bit) the key path will be different. Good catch on that Tom.

@george1421 Thanks, I’ll already test with the full name but it’s same issues.
I’m on W10 64bits system
I’ll test with: regedit.exe /s “mykey.reg”

@Tom-Elliott Thanks you too but my registry key is in HKLM\SOFTWARE\TightVNC
On HKLM\SOFTWARE\WOW6432Node\ i’ve nothing

Thanks you

Tom Elliott

@maouu Can you run the reg delete from the command line as is?

maouu

@Tom-Elliott Yes it’s work perfectly ^^

FWIW then you have the 64 bit version of tightvnc installed otherwise this key would be populated.

maouu

@Tom-Elliott It work from the commande line but when i made a snappin it’s not work.
I have a code 0 but my registry key is not update…

My snappin :
regedit.exe /s “http://192.168.1.6/fog/package/FOG/Key_TightVNC.reg”

@maouu I know tightvnc, so I’m going to ask what is your goal here. Do you want to preset these values using regedit? If so there is a different way to go about this that we use.

maouu

@george1421 At the beginning I just wanted to make a script to uninstall VNC completely and cleanly so I could reinstall it with the right settings on my computer park.
I realized that just by editing the registry [HKEY_LOCAL_MACHINE \ SOFTWARE \ TightVNC \ Server] it worked.

I want to add the following elements:

“IpAccessControl” = “192.168.2.0-192.168.2.255: 2,192.168.3.0-192.168.3.255: 2,192.168.4.0-192.168.4.255: 2,192.168.7.0-192.168.7.255: 2,192.168.8.0-192.168.8.255: 2”

“QueryTimeout” = dword: 0000001e

“QueryAcceptOnTimeout” = dword: 00000001

When I run my script:
regedit.exe / s “http://192.168.1.6/fog/package/FOG/Key_TightVNC.reg” I get a code 0 in Host Snapin History but the registry is not changed

@maouu Here is how we deploy with PDQ Deploy (sorry I don’t use snapins but the install function is similar:

I’m pretty sure if you reinstall with the new parameters they will overwrite what is in the registry. I know this ISN’T what you are looking for, but it works for us.
