Austin PowerShell Users Group – Slides and Code

Last week I had the pleasure of presenting for the Austin PowerShell UG, this is a group run by Ricc Babbitt. During this session I presented the following topic:

Reach the next level with PowerShell

During this presentation I walked the audience through the process of developing a short script to gather information from a system. I pinpointed a number of steps that you can take while developing a script and how to combine the output from different sources in order to get a complete picture of what is running in your environment.

The code has been shared on GitHub in my Events repository:

Configure Windows 10 Blue Light settings with PowerShell

As discussed in the previous post on configuring Lunar Calenders in Windows 10, another interesting feature was also introduced in the 15002 Windows 10 Build: Blue Light Settings. Recently more operating systems have included options for reducing the amount of blue light emitted after sundown. This is easier on your eyes and allows you to fall asleep better at night time.

There are a number of settings that can be configured in the Settings > Display > Blue light settings, settings menu. The settings that can be configured are as follows:

Because automation is a great thing and manually clicking through GUI interfaces is not always optimal I decided to write a PowerShell function to simplify the configuration. For example you could utilize this function to automatically disable the reduced blue light settings when color sensitive work is performed, or lower the amount of blue light emitted as the night progresses. These are some of the actions that the Set-BlueLight function can perform.

To instantly turn of the reduced blue light setting the following code can be run:

1
Set-BlueLight -DisableBlueLight

To enable the reduced color mode and set the color shift to Medium run the following code:

1
Set-BlueLight -EnableBlueLight -ColorTemperature MediumShift

To automatically reduce blue light emitted based on the Day and Night cycle in your geographical location execute this:

1
Set-BlueLight -EnableAutomaticSchedule

The values that are configured by the script are byte arrays in the registry, so it required a bit of reverse engineering to get the values to match the settings in the control panel. The function is currently available on GitHub in my Shared Scripts repository: Set-BlueLight

This function will be added to the CustomizeWindows10 module after I have developed my functional and unit tests to ensure the quality of this function.

Enable Lunar Calendar in Windows 10

As I installed the latest build of Windows 10 on my system I read that it was now possible to set the calendar to also display the Lunar Calendar in the calendar overview. Because I like automating stuff I decided to take a look at where this is configured. Note that the steps in this post are based on Windows 10 Build 15002,

It turns out this in configured in the following registry key:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.lunarcalendar\Current

Interestingly enough, the store cache seems to contain many of the recently released new functionality in Windows 10. At the moment this seems to be the space to watch if you are looking to automate your settings in Windows, although most values are binary so it might take some work to figure out how to configure this.

After setting this value to the three possible options:

  • Off
  • Lunar Calendar with simplified Chinese characters
  • Lunar Calendar with traditional Chinese characters

Unfortunately this because the Data property is a binary string, so this is not that easy to manipulate. The following values correspond with the settings. I will list both the binary strings as well as their base 64 representation.

Settings Byte Array Base64
Off 2,0,0,0,88,33,207,247,241,107,210,1,0,0,0,0,67,66,1,0,16,2,0 AgAAAFghz/fxa9IBAAAAAENCAQAQAgA=
Simplified 2,0,0,0,148,217,114,130,241,107,210,1,0,0,0,0,67,66,1,0,16,4,0 AgAAAJTZcoLxa9IBAAAAAENCAQAQBAA=
Traditional 2,0,0,0,75,55,152,236,241,107,210,1,0,0,0,0,67,66,1,0,16,6,0 AgAAAEs3mOzxa9IBAAAAAENCAQAQBgA=

To simplify settings these values the Set-AdditionalCalendar function that is included in the CustomizeWindows10 module can be used to configured these settings:

To install this module and configure these settings run the following code:

1
2
Install-Module -Name CustomizeWindows10
Set-AdditionalCalendar -Simplified

Uploaded CustomizeWindows10 Module to PowerShell Gallery

Today I finished another major update to the CustomizeWindows10 module I have been working on together with Jan Egil Ring. This module started as a means for me to configure/tweak Windows 10. When I was experimenting with the various Windows 10 insider builds I found myself configuring the same settings on each deployment and I was looking to simplify this process. The module contains a number of tweaks and configuration options to customize and personalize the Windows 10 experience.

CustomizeWindows10-0.0.0.4

In the past I have uploaded the majority of my scripts and functions to the TechNet Script Gallery, but recently I have started using GitHub as a version control system for my scripts. Eventually I plan to upload my entire collection of scripts to GitHub as it provides the opportunity for easier interaction with a wider community but for now this module is my first experiment with both the PowerShell Gallery as well as GitHub.

The module consists of both a PowerShell module as well as a DSC module to allow complete flexibility when applying these settings. In the following example the module will be used to ensure that hidden files are visible and that file extensions are always shown:

1

4
Import-Module -Name CustomizeWindows10
Enable-ShowFileExtension
Enable-ShowHiddenFiles
Get-ShowHiddenFiles
