Hi @Gopal3, thank you for reaching out.

The profiler shows that 2 functions seem to use most of the loading time:

• getCompanyDisplayName (to get interpreter details from the Windows registry)
• shellExec of ${activationCommand} && echo '${getEnvironmentPrefix}' && python ${args.join(' ')} in getActivatedEnvironmentVariablesImpl (to get the activated environment variables for the selected interpreter), which looks like this:

. path/to/.venv/bin/activate 
&& echo 'e8b39361-0157-4923-80e1-22d70d46dee6' 
&& python path/to/extension/pyvsc-run-isolated.py path/to/extension/printEnvVariables.py
