Why can I open Notepad through Notpad and not open WordPad through WordPad?
Because Notepad.exe is located in the C:windows\system32 directory, this directory is already included in the PowerShell environment variable $env:path by default.

C:\WINDOWS\system32; C:\WINDOWS; C:\WINDOWS\System32\Wbem; C:\WINDOWS\System32\WindowsPowerShell\v1.0\; C:\Program Files (x
) \ Windows Kits\8.1\windows performance toolkit\; C:\Program Files\Microsoft SQL Server\110\tools\binn\; C:\Program File
S (x86) \microsoft Sdks\typescript\1.0\; C:\Program Files\microsoft\web Platform Installer\
and Wordpad.exe's "%ProgramFiles%\Windows Nt\accessories\wordpad.exe" directory is not included, you can first enter this directory, then run WordPad, or add the directory where WordPad is located to the environment variable, $env:P ath= $env:P ath+ "%ProgramFiles%\Windows nt\accessories".

By default Type a string, PowerShell will output it as is, if the string is a command or startup program, before the string ' & ' can execute the command, or start the program.
