After uninstalling Python\/Anaconda on your Windows computer, Command Prompt may not open. When you run cmd.exe<\/code>, it flashes on the screen and immediately quits. Also, running DISM and SFC<\/a> (to repair corrupt system files), repairing Windows installation, and running a thorough malware scan may not fix the issue.<\/p>\n

Also, when you open Command Prompt via the Terminal menu in Visual Studio Code, the following error (Error 1: “Incorrect function”) occurs:<\/p>\n

The terminal process \"C:\\WINDOWS\\System32\\cmd.exe\" terminated with exit code: 1.<\/pre>\n
\"vscode<\/p>\n
If you had enabled conda init powershell<\/strong><\/code> and later uninstalled Anaconda, PowerShell might report the following error at every start:<\/p>\n
The term 'C:\\ProgramData\\Anaconda3\\Scripts\\conda.exe' is not recognized as the name of a cmdlet, function, script\r\nfile, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct\r\nand try again.\r\nAt C:\\Users\\Ramesh\\Documents\\WindowsPowerShell\\profile.ps1:3 char:4<\/pre>\n
The profile.ps1<\/code> file would have the following code in it, which auto-starts (PowerShell hook) whenever you launch PowerShell:<\/p>\n
#region conda initialize\r\n# !! Contents within this block are managed by 'conda init' !!\r\n(& \"C:\\ProgramData\\Anaconda3\\Scripts\\conda.exe\" \"shell.powershell\" \"hook\") | Out-String | Invoke-Expression\r\n#endregion<\/pre>\n
Cause<\/h2>\n
This issue occurs due to an incorrect and leftover Autorun<\/code> registry value after uninstalling Python.<\/p>\n
\"autorun<\/p>\n
HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Command Processor
Autorun REG_SZ \"if exist\"<\/pre>\n
The value data might read “if exist<\/code>” which CMD.exe executes at launch and closes automatically. Your Python\/Anaconda installation added the registry value. However, you should be able to launch Command Prompt correctly by running “cmd.exe \/d<\/code>“.<\/p>\n
