@Those who are not the OP but would like assistance with "Explorer is crashing on my machine" issues:
0) Start your own thread. It is wrong to assume that your symptoms are caused by the same root causes as the OP's.
1) Fire up Regedit.
2) Navigate to this key: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting"
3) Right-click in the empty white space, then "New", DWORD, call it ForceQueue and set the value to 1.
4) Reproduce your Explorer crash.
5) Check under C:\Users\<your_account>\AppData\Local\Microsoft\Windows\WER\ReportArchive - there should be a new entry (folder) in there for your latest Explorer crash.
6) Zip up the CAB file from that folder and upload it here.
Analysis of the memory dump (MDMP) in that cabinet file may help to understand your specific Explorer crash.
==========================================
EDIT: If you don't feel confident about doing direct registry edits, steps 1 through 3 above can be accomplished instead by running this command on an elevated (run as admin) CMD prompt:
reg add "HKLM\SOFTWARE\Microsoft\Windows\Windows Error Reporting" /v ForceQueue /t REG_DWORD /d 1
