store.rg-adguard.net is a GUI for generating direct download links to store apps. Peeking at the source of that page, we can piggyback off them to download the content directly, but using PackageFamilyName, rather than Name (in your example it would be Microsoft.HEVCVideoExtension_8wekyb3d8bbwe).

function Download-AppxPackage { [CmdletBinding()] param ( [string]$PackageFamilyName, [string]$Path ) process { $WebResponse = Invoke-WebRequest -Method 'POST' -Uri 'https://store.rg-adguard.net/api/GetFiles' -Body "type=PackageFamilyName&url=$($PackageFamilyName)&ring=Retail&lang=en-US" -ContentType 'application/x-www-form-urlencoded' -UseBasicParsing $LinksMatch = $WebResponse.Links | where {$_ -like '*_x64*.appx*'} | Select-String -Pattern '(?<=a href=").+(?=" r)' $DownloadLinks = @($LinksMatch.matches.Value) for ($i = 1; $i -le $DownloadLinks.Count; $i++) { Invoke-WebRequest -Uri $DownloadLinks[$i-1] -OutFile "$Path\$PackageFamilyName($i).appx" } } } 

This is limited to the x64 version, and the path must point to a folder. It will download the package and its dependencies and save them all as PackagefamilyName(n).appx

Building further on AJ's Answer. Download any app from windows app store with powershell just supply a url from the store and a path for saving.

Usage:

Download-AppxPackage "https://www.microsoft.com/p/dynamic-theme/9nblggh1zbkw" "$ENV:USERPROFILE\Desktop" 

C:\Users\user\Desktop\55888ChristopheLavalle.DynamicTheme_1.4.30233.0_neutral_~_jdggxwd41xcr0.AppxBundle C:\Users\user\Desktop\55888ChristopheLavalle.DynamicTheme_1.4.30234.0_neutral_~_jdggxwd41xcr0.AppxBundle C:\Users\user\Desktop\Microsoft.NET.Native.Framework.1.7_1.7.27413.0_x64__8wekyb3d8bbwe.Appx C:\Users\user\Desktop\Microsoft.NET.Native.Runtime.1.7_1.7.27422.0_x64__8wekyb3d8bbwe.Appx C:\Users\user\Desktop\Microsoft.Services.Store.Engagement_10.0.19011.0_x64__8wekyb3d8bbwe.Appx C:\Users\user\Desktop\Microsoft.VCLibs.140.00_14.0.29231.0_x64__8wekyb3d8bbwe.App 

Code:

function Download-AppxPackage { [CmdletBinding()] param ( [string]$Uri, [string]$Path = "." ) process { $Path = (Resolve-Path $Path).Path #Get Urls to download $WebResponse = Invoke-WebRequest -UseBasicParsing -Method 'POST' -Uri 'https://store.rg-adguard.net/api/GetFiles' -Body "type=url&url=$Uri&ring=Retail" -ContentType 'application/x-www-form-urlencoded' $LinksMatch = $WebResponse.Links | where {$_ -like '*.appx*'} | where {$_ -like '*_neutral_*' -or $_ -like "*_"+$env:PROCESSOR_ARCHITECTURE.Replace("AMD","X").Replace("IA","X")+"_*"} | Select-String -Pattern '(?<=a href=").+(?=" r)' $DownloadLinks = $LinksMatch.matches.value function Resolve-NameConflict{ #Accepts Path to a FILE and changes it so there are no name conflicts param( [string]$Path ) $newPath = $Path if(Test-Path $Path){ $i = 0; $item = (Get-Item $Path) while(Test-Path $newPath){ $i += 1; $newPath = Join-Path $item.DirectoryName ($item.BaseName+"($i)"+$item.Extension) } } return $newPath } #Download Urls foreach($url in $DownloadLinks){ $FileRequest = Invoke-WebRequest -Uri $url -UseBasicParsing #-Method Head $FileName = ($FileRequest.Headers["Content-Disposition"] | Select-String -Pattern '(?<=filename=).+').matches.value $FilePath = Join-Path $Path $FileName; $FilePath = Resolve-NameConflict($FilePath) [System.IO.File]::WriteAllBytes($FilePath, $FileRequest.content) echo $FilePath } } } 

This correctly downloads neutral and x64 packages but untested for arm and 32bit systems. the path must point to a folder. It will download the package and its dependencies and save them all as their original file names while avoiding name collisions like chrome.

function Download-AppxPackage { [CmdletBinding()] param ( [string]$Uri, [string]$Path = "." ) process { echo "" $StopWatch = [system.diagnostics.stopwatch]::startnew() $Path = (Resolve-Path $Path).Path #Get Urls to download Write-Host -ForegroundColor Yellow "Processing $Uri" $WebResponse = Invoke-WebRequest -UseBasicParsing -Method 'POST' -Uri 'https://store.rg-adguard.net/api/GetFiles' -Body "type=url&url=$Uri&ring=Retail" -ContentType 'application/x-www-form-urlencoded' $LinksMatch = ($WebResponse.Links | where {$_ -like '*.appx*'} | where {$_ -like '*_neutral_*' -or $_ -like "*_"+$env:PROCESSOR_ARCHITECTURE.Replace("AMD","X").Replace("IA","X")+"_*"} | Select-String -Pattern '(?<=a href=").+(?=" r)').matches.value $Files = ($WebResponse.Links | where {$_ -like '*.appx*'} | where {$_ -like '*_neutral_*' -or $_ -like "*_"+$env:PROCESSOR_ARCHITECTURE.Replace("AMD","X").Replace("IA","X")+"_*"} | where {$_ } | Select-String -Pattern '(?<=noreferrer">).+(?=</a>)').matches.value #Create array of links and filenames $DownloadLinks = @() for($i = 0;$i -lt $LinksMatch.Count; $i++){ $Array += ,@($LinksMatch[$i],$Files[$i]) } #Sort by filename descending $Array = $Array | sort-object @{Expression={$_[1]}; Descending=$True} $LastFile = "temp123" for($i = 0;$i -lt $LinksMatch.Count; $i++){ $CurrentFile = $Array[$i][1] $CurrentUrl = $Array[$i][0] #Find first number index of current and last processed filename if ($CurrentFile -match "(?<number>\d)"){} $FileIndex = $CurrentFile.indexof($Matches.number) if ($LastFile -match "(?<number>\d)"){} $LastFileIndex = $LastFile.indexof($Matches.number) #If current filename product not equal to last filename product if (($CurrentFile.SubString(0,$FileIndex-1)) -ne ($LastFile.SubString(0,$LastFileIndex-1))) { #If file not already downloaded, add to the download queue if (-Not (Test-Path "$Path\$CurrentFile")) { "Downloading $Path\$CurrentFile" $FilePath = "$Path\$CurrentFile" $FileRequest = Invoke-WebRequest -Uri $CurrentUrl -UseBasicParsing #-Method Head [System.IO.File]::WriteAllBytes($FilePath, $FileRequest.content) } #Delete file outdated and already exist }elseif ((Test-Path "$Path\$CurrentFile")) { Remove-Item "$Path\$CurrentFile" "Removing $Path\$CurrentFile" } $LastFile = $CurrentFile } "Time to process: "+$StopWatch.ElapsedMilliseconds } } if (-Not (Test-Path "C:\Support\Store")) { Write-Host -ForegroundColor Green "Creating directory C:\Support\Store" New-Item -ItemType Directory -Force -Path "C:\Support\Store" } Download-AppxPackage "https://www.microsoft.com/p/snip-sketch/9mz95kl8mr0l" "C:\Support\Store" 

Modified the script so that it delete old versions and only download latest.

Much thanks to Yorai Levi for the original script!

I've found some additional tools that I think are worth noting and hopefully may be of use to others who are using Windows Sandbox.

Although I tried to install Windows Store manually inside Windows Sandbox, that failed due to required components being missing, but this project fills in all of the gaps:

git clone https://github.com/kkkgo/LTSC-Add-MicrosoftStore 

In that folder, simply run Add-Store.cmd and you will now have an operational Store App on the Start Menu in Windows Sandbox, but it is not complete as a few services have to be started also:

# 'config start=auto' is not required on Sandbox, # but is useful for non-Sandbox environments. SC config wuauserv start=auto SC config bits start=auto SC config cryptsvc start=auto SC config trustedinstaller start=auto SC start wuauserv SC start bits SC start cryptsvc SC start trustedinstaller 

Finally, make sure to log in to the Store with a Microsoft account (press the Profile at top right) after which, you should have a fully operational Windows Store app inside Windows Sandbox.

The project was built for Windows Enterprise LTSC (Long-Term Servicing Channel, designed for Windows 10 devices where the key requirement is that functionality and features don’t change over time) that, like Windows Sandbox, uses a slimmed down set of features, but this project works perfectly on Windows Sandbox. The project installs four components to achieve this:
