Upgrading Chocolatey

Of course, Chocalatey itself is upgraded/update with choco:

choco upgrade chocolatey

Installing as non-admin user

The Chocolatey non-administrative section of the docs gives some hints as to installing a package as non-admin user.

It seems to boil down to defining the environment variable ChocolateyInstall with the value of the directory into which the package needs to be installed:

$env:ChocolateyInstall="$home\bin\pkg"

choco feature

Remember parameters (that were passed with -params "…") for future upgrades of an installed package:

choco feature enable -n=useRememberedArgumentsForUpgrades
