Subject: [PATCH] common: Fix WMI exception (#1422)

* common: Fix WMI exception

We currently don't check if WMI service is available when we get the CPU name and the RAM size.
This fix the issue by catching all exceptions and set default values instead.

Close #1353

* remove useless assign

* Fix Exception

* Address comments
