Hi,
to check if command extensions are enabled check the following registry key
1 2 3 4 5 6 | c:\> reg query "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /v EnableExtensionsHKEY_CURRENT_USER\Software\Microsoft\Command Processor EnableExtensions REG_DWORD 0x1C:> reg query "HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor" /v EnableExtensionsHKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor EnableExtensions REG_DWORD 0x1 |
To enable command extensions for a cmd process start it with parameter E:ON
1 | C:> cmd.exe /E:ON |
or within a batch file
SETLOCAL EnableExtensions
Further batch improvements: If you run batch files from a UNC Path cmd generates a warning that the working folder cannot be a UNC path: “Invalid current directory path. UNC paths are not supported. Defaulting to Windows directory”. But when you are sure that your commands/applications supports UNC pathes as working directory you can suppress this by setting
1 | c:\> reg add "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /v DisableUNCCheck /d 1 /t REG_DWORD |
