windows - Powershell: Variable assignment triggers module import -

-

this code works powershell command line generates error when run script:

$key = 'hkcu:\software\microsoft\windows\currentversion\explorer\advanced' set-itemproperty $key hidden 1

when run script, following error:

hkey_current_user\software\microsoft\windows\currentversion\explorer : module 'hkey_current_user' not loaded. more information, run 'import-module hkey_current_user'. @ c:\users\mybitch\desktop\vss-customize-desktop.ps1:19 char:6 + $key=hkey_current_user\software\microsoft\windows\currentversion\explorer +      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : objectnotfound: (hkey_current_us...ersion\explorer:string) [], commandnotfoundexception     + fullyqualifiederrorid : couldnotautoloadmodule

this simple assignment...why powershell try import hkey_current_user module? why behavior different powershell command line?

the error message betrays problem. in script, apparently doing this:

$key = hkey_current_user\software\microsoft\windows\currentversion\explorer

that invalid assignment. should doing describe:

$key = 'hkcu:\software\microsoft\windows\currentversion\explorer\advanced'
