Uninstall an application from PowerShell–Example Windows Live Essential

I was trying to see an option to uninstall and application from the PowerShell after couple of try I got through.

1. Run PowerShell as administrator

2. Get the status of installation, in this example we are trying to check status of Windows Live Essentials installation so enter as,

“Get-WmiObject -Class win32_product | where { $_.Name -like "*Windows Live Essentials*"}”

3. Store the current installation status to a variable, this example ‘$Software’ is the variable
“$software = Get-WmiObject -Class win32_product | where { $_.Name -like "*Windows Live Essentials*"}”

4. Run “$software.Uninstall()” to un install

5. Execute the step 2 to see the status again

Error while running a PowerShell script with 'curl'

This week I was working on a script to back-up a Audiocodes gateway, while running the script I got below error and it took a day of mine to troubleshooting the issue.

Invoke-WebRequest : Cannot bind parameter 'WebSession'. Cannot convert the "%{http_code}" value of type "System.String" to type "Microsoft.PowerShell.Commands.WebRequestSession".At C:\scripts\Untitled4.ps1:20 char:50+ $statuscode = curl -o null.txt $loginurl -w '%{http_code}'+ ~~~~~~~~~~~~~~+ CategoryInfo : InvalidArgument: (:) [Invoke-WebRequest], ParameterBindingException+ FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

Solution which worked for me

After digging lot into the issue came to know that the issue was due to an Alias of ‘curl’

To solve the issue run "Remove-Item alias:curl" from the same PowerShell window or write curl.exe instead of writing just 'curl'

Hope this will help you
