Does PC-Updater keep a log of driver changes that have been made over time? A driver install log would be very useful in debugging "what changed" scenario. I see the list of copies that is kept, but I'm unsure as to what depth is kept (in terms of history). It might be better to create a session for each driver update.
Why do I ask for this? Well, since the last round of driver updates, I know have random blue screen crashes that end up in bug checks in the power system. Something changed, and I'm trying to track it down. To give you an idea - the other evening I got up from my computer and took the trash to the street. Came back 5 minutes later and stared at a blue screen.
Also, one suggestion - I'm going through the application now, and in the model / cpu system box, I noticed a drop down that said "Select One". I don't know if that was recently introduced or not, but it's pretty important. It needs to be highlighted in a much more obvious fashion. Maybe when an update starts, you can popup a reminder or something.
Just some thoughts.
