Windows Explorer Stops Responding with Preview Pane On

[ABerndt65]

Good Morning - For the past couple of days, I have been having an issue where Windows Explorer will stop responding when I am trying to review information on a Network drive. I use the preview pane because I just need to check some information, not open the entire document. I opened the minidump file in WinDbg but cannot figure out what to do next. I am pasting the output below as I cannot even attach a file without Explorer crashing. If anyone has any suggestions how I can resolve this, I would appreciate it.

Download then run the Windows All in One Repair tool from here, disregard the malware guidance but follow the other steps to the letter and in particular ensuring that you first create a new restore point and perform a proper Windows clean boot before running the repair, details for the clean boot here.

Thank you. I will do this as soon as I can. I appreciate your help. This is my work computer so I cannot disable the anti-virus. It is installed and maintained by a 3rd party.

[phillpower2]

This is my work computer

You are welcome but the above is unfortunate, for legal reasons we are not permitted to help with anything other than computers that are for 100% personal use, it may well be your computer but the fact that there is a third party influence involved means that offering assistance is off limits.

[ABerndt65]

I understand. I will continue to research this on my own and will post back if I figure anything out. I have turned off the preview pane and all is working fine.

[phillpower2]

Thank you for understanding and fwiw if using the preview panel is work related it is work who should be sorting this out.

@ABerndt65 - any news?
