Bug Description

BleachBit 0.9.1, depending on version of Windows, uses wmic to find out whether a process like Firefox is running. Apparently this freezes inside a batch file.

There are no more reports like this, so maybe it was idiosyncratic to the user's system

I started getting wmic hang in a batch script Today on a one machine. Entered "wmic" in cmd.exe window at it also was frozen too. At a guess some problem with WMI service . I note On April 2 an "auto update retrieval of third-party root list sequence number" is in event log and a few messages about eventid 36876 return code 0x80096004 in event log today both struck me as unusual. I
have not idea why I would get that last message after googling it meaning.

Never had wmic issue before. After I rebooted issue disappeared. If it happens again I will add information.

I have found two sites suggesting using " wmic .... <NUL" (redirecting stdin to null) for use in scripts to prevent hanging. That would not help cmd.exe prompt.

I have changed any batch script code to include this:
     <NUL wmic /interactive:off process ...
Just in case it makes a difference.
