Is it safe to disable build-in Fraunhofer IIS MPEG Layer-3 Codec (l3codeca.acm)?

Question

Hello. We faced with probem in RDP: when user log in into VM via RDP that codec causes problems with stuck programs and delay audio.

Can we just remove it from registry whith out problems or add ";" to the beginning of string in key?

path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
key:
**msacm.l3acm REG_SZ "C:\Windows\System32\l3codeca.acm" **

Hi,

Please understand it is hard for us to provide suggestion on specific registry key from RDS perspective. If you could like to test the deleting registry key, it is always suggested to do this on the test VM and backup important data.

I just searched a while and found that there were different versions of the codec but all named l3codecb.acm. Not sure if it is related the compatibility of windows versions.
