# Source: https://stackoverflow.com/a/43317244
$path = ".\aws-ec2-key.pem"
# Reset to remove explict permissions
icacls.exe $path /reset
# Give current user explicit read-permission
icacls.exe $path /GRANT:R "$($env:USERNAME):(R)"
# Disable inheritance and remove inherited permissions
icacls.exe $path /inheritance:r

Thank you so much this had been buggin me for quite a while...

In windows 10, using the commands listed above I ran into the following error:

Invalid parameter "$($env:username):(r)"

so, I changed it by "%username%:(r)" and it worked properly. Thanks a lot!!!

thanks!

Thank you

Thank you!
