Win 7 Win Explorer Stopped working, StackHash_0a9e

Hi, 1st time I'm here...after solving all problems since W95, this has me stumped.  I'll yry & simply give the details.  The problem has been occurring for 10 months, very intermittantly.  I'm running 4 different PCs and they all have this issue, and I'll explain what's been done so far too.  The time interval between occurrences ranges 6 hours to some weeks!  All are win7 home x86, with all updates.  Other than what follows, NO OTHER problems whatsoever on all pcs.  The problem manifests in 2 variants as follows:

1. While copying/Pasting files between folder, drives or even USB key drives I will get a popup window saying Windows Explorer has stopped working., and the box offers to provide details or continue.  After grabbing error data (or from EventViewer  or Reliability Monitor, clicking continue and everything goes fine, sometimes Win Explorer may restart.

The error data I have seen many times on your website and others:  The following is shown 99% as:

2. Othertimes, the PC can just be sitting, nothing running, may not even have Win Explorer open.  A similar Windows Explorer Stopped box may pop up, offer no options or buttons and after a few seconds Win Explorer will simply close &/or restart (even if it wasn't open!

Again, this may not happen again for hours to many days.  No recent changes (prior to this stuff) was made.  Did memory test, Norton Scan, Malware bytes scan and SFC /Scannow.  Basically all clean...except 3 or 4 recent enteries were found recently about unable to fix xxx, ran a fndstr "[SR]" parse and they turned out to be a well known set of MS files "telemetry monitoring" I think related to the W10 pushout.

Ran thru Shellx and removed all non MS context menu items (no help).  Read that there was a KB that related to having "Network Discovery turned on", I turned that off on all PC's=no help.  Did NOT apply the Hotfix kb/2494427 ...

since I has no evidence and didn't yet want to complicate the issue??  Tried CLEAN Boot, Safeboot, but the error is so intermittant, the fact that it did NOT help was meaningless.  Following another post on this forum, I have setup a user-crash dump via:

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\explorer.exe]"DumpFolder"=hex(2):43,00,3a,00,5c,00,43,00,72,00,61,00,73,00,68,00,44,00,75,\00,6d,00,70,00,73,00,00,00

So far (2 days...) and no errors, but it may at any moment.  When the fail occurs, I expect the log (dump) will be created & hopefully point to the REAL cause.  If & when the dmp is created, are you able to analyze it & advise?

I also read that a typical reason for this MIGHT be a D.E.P trigger event?  So that's my sad tale...any comments or suggestions would be very much appreciated.
