Add a PowerShell module to manage Windows Updates like you can now with the GUI. Like checking for updates, installing all updates, or a selection of updates, creating a report of pending updates, etc. The Windows Update options in the Server Configuration Manager (sconfig) are very limited.

I do test:

$a=Get-WinEvent -FilterHashtable @{LogName="Microsoft-Windows-PrintService/Operational";"Param5"=
"UserPrinterName"} -Verbose -ComputerName printserver

VERBOSE: Constructed structured query:
<QueryList><Query Id="0" Path="microsoft-windows-printservice/operational"><Select
Path="microsoft-windows-printservice/operational">[([EventData[Data[@Name='Param5']='UserPrinterName']] or
[UserData//Param5='UserPrinterName'])]</Select></Query></QueryList>.

Get-WinEvent : No events were found that match the specified selection criteria.

1. Really the log contain events under the filter!


2. If you copy-paste the Constructed structured query into Eventvwr.msc then you get error!


3. If I do the test with part of the generated query "[UserData//DocumentPrinted/Param5='UserPrinterName']" then you get the events in Powershell and in Eventvwr.msc

Get-Date -UFormat %V is supposed to return the ISO 6801 week number like Unix does. I don't understand what value it currently returns (I think it's nothing sensible), but it definitely is NOT the correct week number!

Invoke-WebRequest & Invoke-RestMethod need a parameter to easily skip/ignore checking for a valid certificate of https uri's. This could be required for a number of reasons such as development site only using self signed certificate while testing.

OS: Windows 7 - 10

Not working example:

$releases = 'https://github.com/hluk/CopyQ/releases&#39;
$downloadpage = Invoke-WebRequest -Uri $releases -UseBasicParsing
$downloadpage.links # <-- hangs here

Other properties seem to work normally.

This example uses basic parsing and works without out. However, the behavior doesn't generally depend on this setting and I had sites that hang on many occasions.

The following issues seems related:

The output of Get-History has Start and End times which can be put together to calculate a Duration. Why not add that to the default formatting of history objects?

As a workaround, I use these:

New-ScheduledTaskTrigger -AtLogOn -RandomDelay 0:15:00; or
New-ScheduledTaskTrigger -AtLogOn -RandomDelay (new-Timespan -Minutes 15)
does not set the delay option. The checkbox in ScheduledTask Panel never gets set.

I try the new CMDLet Get-ComputerInfo, but the most properties in the result are empty.
Only this properties show values:
WindowsBuildLabEx,WindowsCurrentVersion,WindowsEditionId,WindowsInstallationType,WindowsInstallDateFromRegistry,WindowsProductId,WindowsProductName,WindowsRegisteredOrganization,WindowsRegisteredOwner,WindowsSystemRoot,TimeZone,LogonServer,PowerPlatformRole,DeviceGuardSmartStatus

Try also as Admin and with different Hardware and VM's. (Windows 10 x64 Versiom 1607)

De-duplicating a collection, or aggregating similar items in a collection, can be done in linear time via hash sets or hash tables, respectively.

"Select-Object -unique" and "Group-Object", however, both use O(n^2) algorithms that rely only on equality, never leveraging hashing. It's literally faster (by a lot) to use "Sort-Object -Unique", which additionally does sorting.

Blog post at http://latkin.org/blog/2016/08/02/curious-behavior-when-de-duplicating-a-collection-in-powershell/ has more explanation.

It was suggested by Bruce P on Twitter that I open this bug: https://twitter.com/BrucePayette/status/760532657293832192

Running the new Get-ComputerInfo returns the following error
C:&gt; Get-ComputerInfo
Get-ComputerInfo : Unable to find an entry point named 'GetFirmwareType' in DLL 'kernel32.dll'.

This is on a XenDesktop VM hosted on VMWare, so I guess it's due to the desktop being virtualised. OS is Win7x64

Adding an eval alias to the PowerShell core, pointing to the Invoke-Expression command, would help to improve compatibility with Bash scripts on Linux.

Invoke-WebRequest and Invoke-RestMethod commands only support TLS 1.0 protocol. We need to have a native support for newer TLS (1.2) versions for modern web interfaces.

Given a simple array which has been boxed in a PSObject

[PSObject]$o = @(@(Foo,1),@(Bar,2))

Calling ConvertTo-Json returns a weird pointless wrapper around it:

convertto-json $o
{

"value":  [

              [

                  "Foo",

                  1

              ],

              [

                  "Bar",

                  2

              ]

          ],

"Count":  2

}

Which completely breaks round-trip support

ConvertFrom-Json (Convertto-Json $o)

value Count

{Foo 1, Bar 2} 2

As you describe here:

The Get-EventLog command is slow. Using Get-WinEvent is much faster.The Get-EventLog is still easier to use though.
Maybe Get-EventLog could be refactored to use Get-WinEvent

MSSQL Tiger Team gave a great presentation today about new extended events and properties for troubleshooting AoAG. These improvements rely on AG Lease & X-events. It would be great to have a set of Cmdlets added to the AG modules to return information captured by AG-Lease a few examples:

Get-AGDiagnosticEvent
Get-AGLeaseExpired
Get-AGLeaseSystemComponent
