      Great to see you guys back.  I'm looking forward to "season 2" of the show.

      Andrew: you mentioned going through all of the dumps in your C:\Dumps folder.  That would be awesome.  Definitely do that episode!

      Thanks gents! It's really good to have you back. How you're managing to do the shows a month before Win 10 rollout is beyond me! Well done guys and keep up the great work.

      Also glad to see that you guys are back!

      Yes, Andrew definitely go through what we should do with the dumps that are captured in C:\Dumps.  I got tons of crap in there and I always clean it out to save space but never really have time to go in and debug them that much,  Please show us again how to debug these dump files, because often I try to open the dumps in the debugger and it says "APPX" is not a valid win32 application, or sometimes apps don't have symbol files, and I really would love to see how you'd approach figuring out why these crashes and dumps are taking place, Would love to get back into debugging again, i'm getting rusty. Thanks for coming back

      A debugging (C:\Dumps) episode it is then. Since 132, 133 and 134 have already been taped, this episode will be 135 - airing 27th July.

      Email us ( a OneDrive link to any dumps you can't work out. I can't promise to look at them all, or for very long, but I'll try to give you the 1min answer.

      instead of installing the MSIs use admin install ( Here you don't need to remove them later again. I use this tool to do it via GUI:

      Sorry the question was from episode 29

    • User profile image

      What is running on Andrew's laptop which keeps switching mouse pointer to "Working in Background" (hourglass) every 3s or so.

    • User profile image

      Would be good to a 'defrag' going deep

    • User profile image

      @artisticcheese: Yeah - that is a little weird. Hadn't noticed it. Will have to trace it and find out why!

    • User profile image

      @Kiran Prabhu: Send us the dump - We'll take a look. Might be a symbols issue.

      Defrag tools one drive not working ???

    • User profile image

      you should add a link to defrag tools #88 & #89 since you did not discuss 2-tier symbol folder creation for the new SYM folder

      Defrag tools one drive not working ???


      link to defrag tools one drive doesn't seem to be working anymore

      so do we really need those files or can we get them somewhere else?
