  1. BUG: Powershell .net class loads slow since MS-Security Update April 2019

    Since May 2019 Security Rollup for Windows Server 2016, access to .net object via powershell is very slow, when a powershell variable breakpoint is set in the powershell.

    For example loading speed of [System.Environment] takes over ten times with breakpoint set against no breakpoint set.

    Since the behavior only occurs with latest security updates installed (May 2019 (KB4494440) or June 2019 (KB4503267)) i think it is related to the update.

    Did some troubleshooting with procmon until now. For me it looks like when PSBreakpoint is set, there are multiple reads from HKLM\System\CurrentControlSet\Control\Session Manager\Environment__PSLockdownPolicy can't repoduce this when there is no…

  3. Windows Insider Build 18945 - Windows PowerShell is looking in One Drive for the PowerShell Profile

    I don't know why Windows PowerShell is looking for the PowerShell Profile.ps1 file in the Users OneDrive folder.

  5. Set-ADAccountPassword -WhatIf parameter does not work.

    WhatIf is apparently ignored on the Set-ADAccountPassword cmdlet. This bit me really good ********** yesterday and today. It's a big problem when we can't depend on WhatIf working.

    I'm having trouble with the Wait-Job cmdlet on PowerShell Core for Linux. I have a Job created with Start-Job, which I wait for with:

    Wait-Job $job -Timeout 30

    Which should timeout after 30-seconds. However, the command consistently hangs for 2-minutes before it completes. Am I doing something wrong, and if not, could this bug be fixed? I'm running PowerShell 6.2.0 on Ubuntu 16.04.6 LTS.

  8. "Cannot load PSReadline module. Console is running without PSReadline."

    This is an error I get every time I open Windows PowerShell, but not only that, Powershell-Get and PackageManagement are also broken in these ways:

    Install-Module : The 'Install-Module' command was found in the module 'PowerShellGet', but the module could not be loaded. For more information, run 'Import-Module PowerShellGet'.

    Get-PackageProvider : The 'Get-PackageProvider' command was found in the module 'PackageManagement', but the module could not be loaded. For more information, run 'Import-Module PackageManagement'.

    My OS is Windows 10 Pro Insider Preview (Build 18932). I looked for solutions but I really could not find any.

  10. Bug - Blocking psscriptpolicytest Causes PowerShell to Crash

    Major 5 Minor 1 Build 18362 Revision 145

  12. Bug? Invoke-RestMethod returns mis-cased json values for Boolean

    Perhaps a bug in Powershell using Invoke-RestMethod. When querying a particular API endpoint, the json data is expected to return a true/false value.

    When querying with Powershell Invoke-RestMethod, the value comes back as "True" or "False" (Capital first letter).

    When querying the same endpoint with curl, the value comes back as "true" or "false" (all lowercase).

    Not a huge issue, but the is confusing when trying to use a GET to determine the proper formatting for a future POST related to the value. The API endpoint is case-sensitive and doesn't like "True" when expecting "true".

  16. LDAP broken when using Add-ADGroupMember with parameter MemberTimeToLive

    Hi,
    I've wanted to introduce TTL in AD group membership. I've managed to add me to group and after TTL has finished I've been removed. Checked in GUI, via get-adgroup -Identity '***' -ShowMemberTimeToLive -Properties member | select -expand member .
    But when I tried checking with $userGroups = Get-ADGroup -LDAPFilter ("(member:1.2.840.113556.1.4.1941:={0})" -f $adUser.DistinguishedName) or Get-ADUser -Filter "memberOf -RecursiveMatch '$($adGroup.DistinguishedName)'" -SearchBase $($adUser.DistinguishedName) I've got information that I'm still a member of group. Is it bug in LDAP or is there some kind of parameter which is kept?

    Not sure what assembly I need to ensure is loaded

  20. Bug: Ps1 script file with extra extension gets deleted when called from CMD

    When calling PowerShell from CMD and specifying a script file that contains an extra "extension" (extra dot) in the base name, the script is not run but the file is mysteriously deleted:

    Example (run in CMD):

    powershell -file c:\temp\script.txt.ps1

    The same issue when called like this:

    powershell -command "& c:\temp\script.txt.ps1"

    This has been reproduced by me and others on different machines with different paths.

    The same issue exists when called from inside PowerShell like this:

    . "powershell.exe" -file c:\temp\script.txt.ps1
    Start-Process "powershell" -Arg "-file, "c:\temp\script.txt.ps1"

    Note that these will work just fine:

    powershell -command "& 'c:\temp\script.txt.ps1'"
    powershell -command ";& c:\temp\script.txt.ps1"
    powershell…
