There's already a thread for this issue, but seems like my issue is different.
My drives are indexed, so I can search quickly in drives, but I can't search in the My Computer window when I want to search in all drives.
This issue is from the day 1 of installation, but I though that it might be Windows 7 way of not allowing to search in MyComputer. But it works in my office PC
I've tried rebuilding indexes, changed options in Indexing settings and I couldn't even see any connected or disconnected network drive
