Although your latter (TenForums) link seemingly guides to a shortcut creation, you can use the final command line in a batch file instead as a shortcut target.
I have written the following PowerShell script 57498059.ps1
to automatise their (a bit complicated) guide:
Import-Module -Name 'Appx'
$StickyNotesName = 'Microsoft.MicrosoftStickyNotes'
$StickyNotesPack = Get-AppxPackage -Name $StickyNotesName
$StickyNotesManifest = Join-Path -Path $StickyNotesPack.InstallLocation `
-ChildPath 'AppxManifest.xml'
$StickyNotesXml = New-Object Xml
$StickyNotesXml.Load("$StickyNotesManifest")
$StickyNotesExec = 'explorer.exe shell:appsFolder\' +
$StickyNotesPack.PackageFamilyName + '!' +
$StickyNotesXml.Package.Applications.Application.Id
"@$StickyNotesExec" | Out-File -Encoding ascii -FilePath ".\stikynot.bat"
# write `stikynot.bat` to a folder listed in Windows %path% variable
# you can type `stikynot` in the run prompt or `cmd` prompt then
"$StickyNotesExec" # return value: cmd command to launch Sticky Notes
Write-Host "$StickyNotesName - done" -ForegroundColor Cyan
<# check if it works #>
Invoke-Expression "$StickyNotesExec"
<##>
Result (and Sticky Notes
app runs on my Windows 10):
PS D:\PShell> .\SO\57498059.ps1
explorer.exe shell:appsFolder\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe!App
Microsoft.MicrosoftStickyNotes - done
type .\stikynot.bat
@explorer.exe shell:appsFolder\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe!App
