Different -notmatch operator results in windows 10 1703, 1607 with Powershell 5 RRS feed

  • Question

  • Hi all, hopefully someone can point me in the right direction as this is driving me loopy...

    I'm checking if my various scripts are compatible with Windows 10 1703. They work as intended in Windows 7 and Windows 10 1607, but with 1703 the operator behaviour is different.

    This is the script I'm running on each of the systems:

    $PSVersionTable.PSVersion
    [environment]::OSVersion.Version
    $userProfiles = (get-ChildItem c:\users).name
    write-host "`nUser profiles on this system: $userProfiles "

    $userPNMatch = (get-ChildItem c:\users).name -notmatch "Administrator|Public|service|.1|default"
    write-host "`nUser profiles on this system with -notmatch operator: $UserPNMatch"

    Output for Windows 7

    User profiles on this system: Administrator philip.allen.1 Public w10user 

    User profiles on this system with -notmatch operator: 

    I'd like to be able to populate a variable using the -notmatch operator and then pipe contents to foreach, whats going on here?

  • Thanks for your reply. I tested this out on two more w10 1703 machines. A machine that was built via inplace upgrade operates correctly, however a machine freshly built complete with windows updates yields same results.

  • I have W10Pro 1703 and cannot reproduce your results:

    PS D:\scripts> notepad get-userprofiles.ps1
    PS D:\scripts> .\get-userprofiles.ps1

  • The variable is an array just as it should be:

    PS D:\scripts> $userPNMatch = (get-ChildItem c:\users).name -notmatch "Administrator|Public|service|.1|default"
    PS D:\scripts> $userPNMatch
    jjones
    LocalTest
    MSSQL$SQLEXPRESS
    MSSQLFDLauncher$SQLEXPRESS
    MSSQLLaunchpad$SQLEXPRESS
    ReportServer$SQLEXPRESS
    SQLTELEMETRY$SQLEXPRESS
    TestAuth
    TestUser
    testuser4
    PS D:\scripts>
