Configure Storage Sense using PowerShell

Recently the Storage Sense functionality has been added to Windows. Unfortunately there are no PowerShell commands available to manage this so I decided to write this function to be able to manage the different settings that are available in regards to Storage Sense.

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

By clicking: Change how we free up space, the following options become available:

So in order to configure this using PowerShell I have created the Set-StorageSense function with the following parameters:

  • EnableStorageSense
  • DisableStorageSense
  • RemoveAppFiles
  • ClearRecycleBin

So if you would like to disable this functionality and not have Windows automatically clear out temporarily and otherwise obsolete files you can run the following command:

1
Set-StorageSense -DisableStorageSense

Alternatively the other options can also be configured, the following command Enables Storage Sense and configures all cleanup options to true while displaying verbose output:

1
2
Set-StorageSense -EnableStorageSense -RemoveAppFiles $true`
-ClearRecycleBin $true -Verbose

This would of course not be complete without being able to query this data as well, which is possible using the Get-StorageSense function:

Although I looked into manually triggering the Clean Up job, this is something that did not seem possible, I used Sysinternals Procmon to determine which command is associated with that. But even when running this as the System account it did not appear to clean anything. I will provide the execution in case it is of value for anyone else:

c:\windows\system32\svchost.exe -k localsystemnetworkrestricted -s StorSvc

Let me know if PowerShell functions like these are useful to you and if it works as expected. Do note that this functionality is only available in recent builds of Windows 10.

Windows 10 – Start Windows applications from Bash

Working with Bash on Windows, I can say that it significantly simplified the way I can work cross-platform. It has allowed me to use native Linux tools, when working with Linux systems, which is a big step up from using a mix of compiled for Windows Unix tools and GUI applications. Because of this unique functionality Windows 10 has a big lead over any other platform as my day-to-day platform.

For example it is possible to add a new Windows users account directly by using the net.exe tools:

1
net.exe user /add testaccount

Alternatively it is also possible to start Windows PowerShell in Bash to execute a command, for example it becomes possible to use PowerShell to determine which processes are running in the Windows environment and the ps command to determine what is running in Linux:

1
2
powershell.exe -nop -command "Get-Process | Select-Object -First 10"
ps -aux

For me the greatest advantage is the fact that Windows executable files can also be directly called from bash, simplifying the interaction between the different OSes. An example of this is opening explorer in your current working folder in the bash terminal:

1
explorer.exe .

When a path is not accessible for the Windows application, for example anywhere in the Unix file system, a proper error message will be displayed:

1
explorer.exe .

Using this same method it is also possible to add the path to your favorite script editor to the Bash on Windows path allowing them to be directly called from the console. In the following example I will show how to open VSCode directly from Bash:

1
2
3
ls README.md
export PATH=$PATH:/mnt/c/Program\ Files\ \(x86\)/Microsoft\ VS\ Code/
Code.exe README.md

For more information and example of what is possible with the Bash commandline on Windows or I recommend following the Windows Command Line Tools For Developers blog on MSDN.

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
