I have run most revisions since r6373 and at the moment am running r4848 and never had a crash while decoding yet.
I have windows 7 with all updates installed. It is a six core amd unit with 8GB ram. WSJTX is set for decode deepest and the waterfall to bins/pixels 3 and the default jt65 2500 jt9 Using split mode on my ic-7000 I can operate anywhere displayed on the waterfall with no issues. The system is left on most of the time, with random downtimes to allow the missus to run her version or to see if there are any issues with the latest builds. Your 1st update is for explorer which I don't use anyway (I use firefox and chrome) though as explorer is integral to windows I would think I have the update. The 2nd update seems to be causing issues for some and nothing for others regardless of if they use wsjtx or any ham related software. I'm wondering if the issues are hardware/software rather than just software ?, not saying that there is a problem with your hardware but there are so many pc configurations it could be something totally random causing these issues.

Testing was done on 3 different versions of WSJT-X (r3673, r4400, & r4633) in total isolation from the world, save "on-air" signal input. Almost every permutation of disabling software, option settings, etc. were employed in a very large number of tests. Each test was performed after a complete scrubbing of my laptop's hard drive, memory, and drivers. No positive effects were observed during the tests. I finally uninstalled every Windows update placed into service in Dec 2014, and re-tested. Results were most encouraging, with long runs of each WSJT-X version before a hiccup. Hiccups were cured by restarting WSJT-X (not the optimum resolution, but much better than others found to date). Final confirmation of WSJT-X - Windows interaction having some relationship to the errors observed came when each Windows update was individually re- installed. No change to the much improved operation of WSJT-X versions was observed until two different updates were installed. Each caused a slow- down of decoding, increased errors, and frequent Decode lock-ups. The "offending" Windows Updates are: KB3025390 - major "offender" KB2952664 - minor "offender" With these two Windows updates uninstalled, and everything but the kitchen sink attached to the laptop and every bit of software normally used in weak signal operations here running, the results of testing were impressive. Fast decoding (I use "Deepest" decoding), and a noteworthy improvement in mean time between errors. Best, only one decoder lock-up over 6+ hours of testing. If a KV error occurs, with or without the pop-up error window, normal operation continues. The pop-up error window can be closed when it appears - no observable deterioration in normal operations occur when that pop-up appears, nor when it is manually closed. Any thoughts about this line of testing and its results?
