 Method for getting latest version of powershell from winget
 
-```powershell
-$winget = winget search --Id Microsoft.PowerShell --exact;
-$PSLatest = $winget | where-object {
-  $_ -match "Microsoft.PowerShell"
-} | ForEach-Object { 
-  $_ -split "\s+" | Select-Object -Index 2 
-}
-```
+*manually*
 
 ```powershell
-Get-Command pwsh -ErrorAction SilentlyContinue | Select-Object -ExpandProperty Version
+winget install --id Microsoft.PowerShell --exact
 ```
 
-This method might work better
+*programmatically*
 
-```PowerShell
-$UpdateCheck = [pscustomobject]@{
-  Current=[version]($PSVersionTable.PSVersion | Select-Object Major,Minor,@{N="Build";E={$_.Patch}});
