VDI Client Registry Settings Follow


Registry keys can be used for troubleshooting or fine tuning performance with your VDI setup. If the registry key or sub key is not present, you can create it. Once you have created or edited a registry key, restart the Zoom client for the change to take effect. Using registry keys for non-troubleshooting purposes is not recommended. Changing the LogLevel value in particular can generate a large amount of unnecessary files. 

All registry keys listed will work in the HKEY_LOCAL_MACHINE (HKLM) and HKEY_CURRENT_USER (HKCU) hives, except where otherwise noted. Zoom will check the current user directory, then check the local machine directory for the key. If the same key is set in the HKLM and HKCU hives, the value in the HKCU hive will be used. Keys only need to be configured on a virtual machine's registry table to take effect.
