Show progress while uninstalling

spiceuser-e7rf8 · 2021-11-18T02:34:17.000Z

Hi

I need to uninstall eset off of 1000+ machines using sccm I have a script to remove and can do it at log on, but as there is no requirement for user interaction, I just want a powershell progress bar from 0 to 100% (doesnt have to be accurate)

my script to remove AV is this and works fine

$avsoftware = get-wmiobject Win32_Product | Where Name -eq ‘ESET Endpoint Antivirus’
$avguid = $avsoftware.IdentifyingNumber
$avagent = get-wmiobject Win32_Product | Where Name -eq ‘ESET Management Agent’
$agguid = $avagent.IdentifyingNumber

msiexec.exe /x $agguid /qr PASSWORD=“xxxxxx”
start-sleep -Seconds 120
new-item c:\windows\esetremoved.txt
cls
msiexec.exe /x $avguid /qr /promptrestart PASSWORD=“xxxxxx”

and the script to do a generic PS progress bar is this

for ($i = 1; $i -le 100; $i++ )
{
Write-Progress -Activity “Updating your Anti-Virus Software - Please wait for AUTOMATIC REBOOT” -Status “$i% Complete:” -PercentComplete $i
Start-Sleep -Milliseconds 2500
}

Now I would like some how to have one script that does the eset lookup and can show a progress bar all in one

I have tried calling the scripts individually and it fails to display my generic progress bar

I tried using start-process -argumentlist “-file \path to file\file.ps1”

but not having success

thanks

Cliff

Welcome to the community.

Write-Progress works best with loops and iterative processes, because usually you will know how many iterations to perform, so the progress can be predictable. For uninstalling an MSI, Powershell will not be able to predict the progress for you. You can estimate it, but the progress bar will not reflect reality. Do you know how long the ESET uninstall usually takes? You can use Start-Sleep in a loop to run for approximately that same length of time.

Also, Win32_Product is horribly inefficient and actually a bit evil. It causes the OS to run a consistency check on ALL installed software. You should avoid it, if possible.

First of all, DO NOT USE THE WIN32_PRODUCT wmi class! It is bad practice and can cause unintended consequences. See links below for more info:

Win32_Product Is Evil. | Greg's Systems Management Blog
Why Win32_Product is Bad News! - SDM Software

Instead, you will need to query the following registry keys to identify the application’s GUID:
HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall

HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Second, in order to launch the Powershell script that will display the preloader you can easily just run it with the following Powershell line:

& "PATH GOES HERE\SCRIPT GOES HERE.ps1"
