Windows 10 and 11: installing WSL2 does not require winget, Chocolatey or Scoop

Posted by jpluimers on 2023/05/18

After using Chocolatey for a long time and writing about it, I have written a few articles on other Windows package managers like winget and Scoop.

Part of the reason was that I wanted to install new systems in a semi-automatic way including WSL2 (Windows Subsystem for Linux 2).

As I have spent quite some time getting treated against metastasised rectum cancer, I missed part of the evolvement of WSL into WSL2 and of the winget evolvement.

The good news is that this simplified the scripted installation of WSL2 a lot, as over time, this got very easy, as confirmed in these posts/messages I found via [Wayback/Archive] winget wsl2 – Google Search:

I even found back this was announced when I was still in hospital: during the Build 2020 conference. A summary is at [Wayback/Archive] The Windows Subsystem for Linux BUILD 2020 Summary – Windows Command Line describing the introduction of wsl.exe --install and that it defaults to install WSL 2 as back-then already most Windows Insider build users using WSL had switched from WSL 1 to WSL 2.

Back to installing

Yesterday, in  Windows “equivalents” for bash backticks in cmd and PowerShell, I showed how to get the wsl.exe information:

C:\temp>PowerShell -Command "SigCheck "$((Get-Command -CommandType Application wsl).Path)""

        MachineType:    64-bit

This was on one of my Windows 10 systems with version 21H2.

The installation progress was as follows and took ome 3 minutes on a 50 Mibit/s fiber connection:

C:\temp>wsl.exe --install
Installing: Virtual Machine Platform
Virtual Machine Platform has been installed.
Installing: Windows Subsystem for Linux
Windows Subsystem for Linux has been installed.
Downloading: WSL Kernel
Installing: WSL Kernel
WSL Kernel has been installed.
Downloading: Ubuntu
The requested operation is successful. Changes will not be effective until the system is rebooted.

Time to play around (:

Windows “equivalents” for bash backticks in cmd and PowerShell

Posted by jpluimers on 2023/05/17

A while ago, I needed the file information of wsl.exe on one of my Windows systems.

On Linux, I would do something like file `which bash` where file will give the file details and which gets you the full path to bash.

The file equivalent on Windows for me is [Wayback/Archive] Sigcheck – Windows Sysinternals | Microsoft Docs, which is part of [Wayback/Archive] File and Disk Utilities – Windows Sysinternals | Microsoft Docs.

The which equivalent on Windows for me is [Wayback/Archive] where | Microsoft Docs.

Disabling the Windows 10 news (and weather) feeds

Posted by jpluimers on 2023/05/11

I finally got annoyed enough to figure out how to disable the Windows 10 news (and weather) feeds.

At first I thought the solution in this post worked for Windows 11 as well, but re-testing in Windows 11 it does not or does not (or not any more: given so many new Windows 11 releases with ever changing functionality I’m not surprised).

Disable Windows news feeds for current user

Failure: just disabling the news feed will automatically get it reset by explorer.exe

Based on the below sources, I made this small batch file:

Restart Windows explorer with an UAC administrator token

Posted by jpluimers on 2023/05/10

Sometimes, you want to restart the Windows explorer. This is already an exception case which you want to do when explorer hangs (for instance when taskbar icons do not respond any more), or has files locked which need to be modified. I described the latter in Inno Setup: Program Folder not showing up In Start > All Programs , with this very simple restart script:

taskkill /F /IM explorer.exe
start explorer

Even more exception is wanting to run explorer with a UAC elevated administrative token. I sometimes do this when moving around stuff from other users on the same computer without having them logged on (as that would lock the files or directories to be moved around).

The risk of running explorer under UAC elevation, is that any program you start will also start UAC elevated, so beware what you ask for…

This is how you start explorer under UAC elevation:

pwsh.exe -nol -noni -nop -w hidden -c "taskkill /f /im explorer.exe; start explorer -v runas -a /nouaccheck"

or if you run an older Windows version of PowerShell:

PowerShell.exe -nol -noni -nop -w hidden -c "taskkill /f /im explorer.exe; start explorer -v runas -a /nouaccheck"

These command-line options and verbs are used:

Time to explain a few:

llamasoft/polyshell: A Bash/Batch/PowerShell polyglot!

Posted by jpluimers on 2023/03/16

PolyShell is a script that’s simultaneously valid in Bash, Windows Batch, and PowerShell (i.e. a polyglot).

[Wayback/Archive] llamasoft/polyshell: A Bash/Batch/PowerShell polyglot!

Need to check this out, as often I have scripts that have to go from one language to the other or vice versa.

Maybe it enables one language to bootstrap functionality in the other?

The quest

The above polyglot started with a quest to see if I can could include some PowerShell statements in a batch file with two goals:

  1. if the batch file started from the PowerShell command prompt, then execute the PowerShell code
  2. if the batch file started from the cmd.exe command prompt, then have it start PowerShell with the same command-line arguments

The reasoning is simple:

  1. PowerShell scripts will start from the PATH only when PowerShell is already running
  2. Batch files start from the path when either cmd.exe or PowerShell are running

Lots of users still live in the cmd.exe world, but PowerShell scripts are way more powerful, and since PowerShell is integrated in Windows since version 7, so having a batch file bootstrap PowerShell still makes sense.

Since my guess was about quoting parameters the right way, my initial search for the link below was [Wayback/Archive] powershell execute statement from batch file quoting – Google Search.

I have dug not yet into this, so there are still…

Many links to read

These should give me a good idea how to implement a polyglot batch file/PowerShell script.
