[ bug report] After uninstalling anaconda, Windows cmd will become unavailable

[RidiculousDoge]

Expected Behaviour

Uninstallation of conda does not affect cmd

Actual Behaviour

Environment Path still has cmd.exe，but the program cannot be used.

Steps to Reproduce

• Uninstall anaconda
• press win+R, enter cmd

ST3, Anaconda and OS versions

Windows10 x64, anaconda 2021-11

How to repair:

conda seemingly modified the Windows registry. Editing the registry HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor autoRun to "" solves this problem. But It is obviously an unexpected behavior for conda to change this registry.
