Find File or Handle freezes Process Explorer RRS feed

  • Question

  • While using CTRL-F to search for handles related to Corsair iCue, all of a sudden Find (CTRL-F) no longer works, and PE stops refreshing until I change the refresh rate.

    This is Windows 8.1 Pro w/ current Windows updates applied (9/30/2020).

    I changed PE to latest release and same issue .

    I've uninstalled the ICue app, and no change.

    I've changed AV app from McAfee to Symantec and no change.

    Windows Defender has been and is still turned off.

    Any ideas?

  • I think that to examine this problem a full memory dump is necesary to be taken when the probelm happens..

    Try configuring the machine to get a keyboard initiated full memory dump following these instructions:

    Forcing a System Crash from the Keyboard - Windows drivers | Microsoft Docs

    Take a dump just to validate it works.

    when you repro again the problem, force the dump, and then send an emai to Mark Cook at SysSite@microsoft.com and work with him to find the problem.

  • Mario,

    Any alternative for submitting a full dump considering security and privacy issues?

  • Mind you, CTRL-F still works in all other apps as expected.

    It's only PE where there is an issue.

  • unfortunately PE uses a kernel driver.. and at the moment we don't know if it is blocked in the user intereface or in the driver for this i suggested a full memory dump.. if you still can move around in explorer you can use procdump to create a dump a process explorer. Even better you can use procdump to monitor PE until it blocks and then capture one or more PE dumps and send them in for analysis..

    You can run procmon this ways:

    procdump -ma -n 10 -e procexp64.exe

    or better

    procdump -ma -n 10 -h procexp64.exe

    In this case if the main window hang for more than 5 seconds it will write a dump of the process..

    I'm still convinced that the best thing to do is a full memory dump, but we can start trying this way..

    send the data in to Mark Cook as soon as you reproed the problem.

  • Mario, I'm getting "dump count not reached" in both command variations.

    I added -t...

    but basically PE doesn't hang per se but the refresh speed (which is still at the default) can be changes to .5 or any other speed and functionality resumed.

    So I'll let you determine if the above dump would be worthwhile.

    If so, should I cantact Mark to figure out how to get the dump to him (dump size (7zip) is 30MB.

  • Yep, try contacting Mark at Syssite@microsoft.com and let's see what he can found.

    Thanks
