When you install SnapCenter Plugin for Windows on your host, it will install the SnapCenter Service for Windows (SCW) on the host and push all powershell modules to C:\Windows\System32\WindowsPowerShell\v1.0\Modules\SnapDrive
Remember that this directory path is same for SnapDrive.
You can uninstall Snapdrive and install SCW service. Note that not all snapdrive cmdlets will work with SnapCenter.
If your system is still having old snapdrive PS modules, during SnapCenter plugin installation the packages are always overwritten to the directory file.
