Wasted time but fixed explorer crashing on Windows 7 x64 laptop, purchased with one key factory reset. Did not have an install disk.
Two week research for fix to Windows 7 64bit with explorer continually crashing.
This was even happening in SAFE MODE for me.
I would get the message windows\system32\bthprops.cpl is damaged or unable to run.
I’m required to click OK to continue.
Then once I login it will shortly get the message explorer is ending…….. searching for FIX……
----explorer restarting…… and the cycle continues with explorer is ending…. Etc.

You can end this by CTRL + ALT + DELETE and choose Start Task Manager.
Click on the Processes tab (near the top) and find explorer.exe from the display.
Click on explorer.exe (will color the line to show it has been selected) and then click End Process
(you may have to do this a 2nd time depending on the cycle of explorer.exe crashing.)

What you can do now is click on FILE (upper top left side of Task Manager )
And click on New Task (run…) you can browse and successfully run your web browser from here.
( not everything will run this way. Because of my problem, they may crash and end.)
What I did was:
Key in “control panel” and click OK you can run setting changes. I was able to run and create a disk image backup to an attached external disk drive with this method. For me it was part of my discovered method in safe guarding this long time consuming process of repairing my Laptop computer.
I did not want to do a factory reset and rebuild all my applications and see if could recovery most of my data from backups.
Before this I had tried several tips from searches on the internet like deleting old apps that I was no longer using. But, my issue was in the system. The 64bit hardware running windows 7 was rejecting 32 bit applications and crashing explorer.

My advice is based on this You Tube video:
Repair install to fix windows 7 without reformatting by Britec
I needed any install disks for windows 7. ( My disk for upgrading Vista to windows 7 32 bit will assist )
I needed to make an image backup. ( even though I knew I would not use it once I was successful.)
I needed the CD Key nnxxx-xnxxx-xxxxx-xnxnn-xxxxx for my Laptop install of windows 7 64bit.
This is important and I had to download the free version of “Magic Jelly Bean KeyFinder” and install it so I could double check that I knew the laptop’s CD Key.

Follow the advise from the video.
Deleting the service pack 1 update that was performed in windows update ( control panel task)
Was a long running task and involved an automatic reboot. Appeared to remove many of the separate updates. Surprisingly, the crashing of explorer.exe also went away at this point. So I created a restore point at this time. Before attempting the “UPDATE INSTALL” portion of Instruction from the video.
That step was done using the borrowed CD. I had to leave the processing running over night.
( 6 + hours)
When I resumed there was a Microsoft update that needed a retry.
However, research indicated that I needed to download and run:
Windows 7 System Readiness Tool.
(this was a 10-15 minute run and it gave me a successful retry on the KB947821-V34-x64 service pack which was also a long run.)
I checked for more windows update through control panel.
Created a new restore point.
Reviewed my applications and data files to see that I indeed had a successful repair of my system.
Time for a new and important disk image backup.
Also cleanup some documents that I no longer needed or wanted.
Create another restore point and then
Did the new disk image.
Note: I though I was done, however the next day, windows update had 136 updates for me.
And one more after that with the reboot.
Happy to be at this point finally.
Sorry for the level of instructions. They are not detailed exact step by step. They are for those who need the concept and are able to apply it to their needed knowledge.
