WINDOWS EXPLORER

can you give me event details ?

you will find in that in event log.. check if anything is noted in event log

Also run below FIxIT if that helps

This means that Windows Explorer is crashing. When it crashes, the desktop environment and taskbar disappers. Windows automatically re-launches Explorer again shortly after it crashes.

WHY it is crashing could be any number of things, but this is something that shouldn't ever happen, certainly not in Windows 7 Professional x64.

Either there's a malicious (or maybe just poorly written) program on the computer that integrates with Windows Explorer and is causing it to crash, or there's something wrong with the operating system.

To check if the operating system files have been tampered with or otherwise corrupted, open an administrator command prompt and run "SFC /SCANNOW" and let it run.

Check in Control Panel->Uninstall a Program for any unusual programs, and remove suspicious/malicious stuff, or programs that have obvious Explorer integration (e.g. Dropbox, Skydrive, SVN, backup products, Office Groove etc., these are programs that integrate directly with Explorer and changes the way Explorer displays files)

As Haresh said, you might be able to find clues to point you in the right direction in the event log.

If this crashing has just recently started happening you can try System Restore, and attempt to restore your system components to an earlier date when it was working.

If you come up empty on all those fronts... I think it's time to just re-install Windows.

But rather than reinstalling Windows using a Clean Install, use a Repair Install.

It should not affect your installed programs or personal data, but a back up first is always a good idea.

i'm curious for the outcome; in all these cases i had, a fresh install was needed

Hi Everyone!
My PC was inaccessible for a few days. Now, I am back!
I shall peruse your comments and respond to you all by Monday.
From what I read so far, I am praying that there is nothing critically wrong (yes, I am hoping for an easy fix).
Thanks for your time, knowledge, and patience.
I will return on Monday.

So far:
[1] Fix-It does not work. It is expired.
[2] SCANNOW found nothing amiss. No errors.
[3] Registry Retriever was downloaded (but not installed) from Windows 7 forums.

Conclusion: no solution yet.

I am going to spend a day or two testing the PC and see what happens. I have some unconfirmed suspicions which I must test. Will contact in a day or two.
Again, Thanks.  GadgetDude

GadgetDude--
Of course it is your call, but I would not use Registry Retriever
 http://www.softwaregeek.com/registry-retriever/p1.html

Software programs that automatically alter the registry can often lead to non-bootable PC's.

AGREED!!!
Do not use Registry Retriever.

Why do I feel that an OS "repair" is my only alternative?
I need to investigate my system further.

GadgetDude--
Remember a Repair Install is still an option and will not affect personal data or installed programs.

i doubt that a repair will do it...but plse try

I will get back to you soon. I have been sick.

In searching both Microsoft Support and Windows 7 Forums, I ran across something intriguing. I cannot say whether this is the solution (time will tell as I test it out) but the following was recommended:

[1] in "C:\Windows" you will find a folder "Explorer". That is "explorer.exe".
[2] Copy this folder and paste it into the "System32" folder.
[3] Claimed Result? The Windows Explorer crashing and restarting stops.

I am not an expert. This is a suggestion I discovered on Windows 7 Forum.
What was suggested has been done, and this weekend I am testing to see if it works.

GadgetDude--Since you are running Win 7 64 bit, You already have copies of explorer.exe in both the Windows folder and the Windows SysWOW folder.
Doing what you suggest should have no effect unless you change the path in your Windows Explorer shortcut to Windows\System 32.
But, sure try it.  I do not think it can hurt anything.

i also added  : plse try

I give up!!!
The repair of Windows would not be possible for one reason: this laptop was originally with Windows Home Premium. Using Microsoft, I upgraded to Windows 7 Professional X64.
So the original disk is Windows Home Premium.
Doing what is suggested would be an enormously complicated series of tasks I am not comfortable with.
My only alternative seems to be closing this "Question" down; and, hiring some "professional" to come on-site to my home and fix it.
I thank you all so very, very much for your valuable time and efforts.
You are very much appreciated and I am grateful despite the circumstances.
THANKS!  GadgetDude

Although inclined to give a "B" grade because no real solution is forthcoming, I chose "A" to honor the time and the effort that has been put forward for this problem.
I accepted a specific "solution" as a backup to what I have decided to do.
I have hired a Senior Tech guy to come to my home (for a fee) and he claims that the problem will be solved.
Only time will tell.

P.S. I forgot to tell him that my 2 favorite Latin phrases were "Nullus Credas" (Trust No One) and "Omnia Quaere" (Question Everything).

THANKS!  GadgetDude

GadgetDude--
You are welcome.  All's well that ends well.
If you are willing let us know the outcome.
