Question

Is there a way to remove/ uninstall a self signed certificate from my store using powershell ?

I tried

Remove-Item cert:\LocalMachine\My\$thumb

it did not work, I got an exception saying “Provider does not support this operation”

I also tried

 certmgr.msc /del /n "MyTestServer" /s MY

it did not work either

How can I uninstall certificate from store ??

Thanks in advance
Jeez

Answer 1

This approach seems to apply to Powershell 2 only and thus it is outdated.

Remove-Item does not work with certificates because der cert-provider is readonly in powershell. Found that information here

$store = new-object system.security.cryptography.x509certificates.x509Store 'My','CurrentUser'
$store.Open('ReadWrite')
$certs = @(dir cert:\currentuser\my | ? { $_.Subject -like '*MyTestServer*' })
foreach ($cert in $certs) {$store.Remove($cert)}
$store.close() 

I found the solution here in the comments. So it is untested.
