CLOSED Desktop Vanishes, Windows Explorer Stops

Recommended Posts

My Desktop icons and taskbar periodically just disappear, leaving only my wallpaper image visible. The only way I have found to recover (without a power-off/on hard boot) is to bring up Task Manager and log off, then log back on at which point my Desktop is restored.

"Windows Explorer has Stopped Working" keeps popping up in mid-session, the only recovery option being to Restart Windows Explorer, thereby losing whatever I had been working on.

I have run sfc /scannow to see if any Windows files were corrupt, but it reports no problems found.

The only common factor I can find in the various "solutions" found on various sites for both of these issues is Malware, so here I am, on bended knee- "Help me, Obi-Wan Kenobi, you're my only hope!"

Logs are attached, please help. Thanks.

Close Notepad.

 

NOTE: It's important that both files, FRST, and fixlist.txt are in the same location or the fix will not work.

 

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system

 

IMPORTANT: Save all of your work, as the next step may reboot your computer.

 

Run FRST and press the Fix button just once and wait.

 

If the tool needed a restart please make sure you let the system restart normally and let the tool complete its run after restart.

 

The tool will make a log on the Desktop (Fixlog.txt). Attach it to your reply.

 

NOTE: If the tool warns you about an outdated version please download and run the updated version.

 

Also, let me know how the machine is running now, and what remaining issues you've noticed.

I did as you instructed, and fixlog.txt is attached. Thank you very much for whatever you did.

Interestingly, as I was reading through the (report? action summary?) that popped up after pressing the FRST Fix button, my desktop icons and taskbar vanished before my eyes! It's the first time I have ever actually seen it- usually, it vanishes while hidden behind my browser or game window or whatever else I'm working on.

I'll let you know how it's doing since running the fix in a couple of days if that's OK with you- it'll take that long for me to see what's different.

Thanks again for your time & expertise.

The icons and taskbar disappearing was expected, as I reset the Winlogon value to its default.

Run a fresh scan with FRST, attach the new FRST reports to your reply.

Well, the Desktop has disappeared once and "Windows Explorer has stopped working" twice in the 24 hours since I ran the fix.

Here are the new FRST reports, and again, whether "we" (lol) succeed in rooting out and fixing this scary issue or not, I really appreciate your help.

Something is causing Explorer to crash.  Look at your logs it is not Malware related.  You will need to examine the crash dumps to determine what is causing Explorer.exe to crash.
