explorer.exe crashes

[sosborne]

I am running Windows XP SP1 Pro. I installed Windows XP SP2. Now, when I open up Windows explorer, and right-click on any folder or file, explorer hangs for a long time, then closes, putting me back to my desk top. I can open files and folders, but am unable to right click on anything without explorer cashing. I uninstalled SP2, and everything works fine. Can anyone help?

[lespaton]

That happened to me on SP1. I fixed it by getting SHELLEXVIEW...

ShellExView download site.

After starting it up the items you are interested in are listed under... Type/Context Menu. Click on the Type header to sort the items into category. Select and right click an item to disable it.
I disabled everything that looked like an add-on resulting from a software install. That fixed my problem.
I then enabled items, one at a time, to determine what was causing the problem.

So far I have been OK on SP2.

You need to turn OFF the DEP via the boot ini

My Computer -> properties -> advanced -> startup and recovery ->

hits the edit button and change the line from

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /fastdetect /NoExecute=OptIn

to

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /fastdetect /NoExecute=AlwaysOff


eg change optin to alwaysoff

this will solve ur problem i guarentee , IGNORE the poster above

Could you educate the rest of us on what this change actually does to XP ??? Since you guarantee it, you must know in detail what is the effect.

Open up your favorite TEXT editor. Copy the following four lines of text and paste them into your text editor:

regsvr32 /s %windir%\system32\mmcndmgr.dll
regsvr32 /s %windir%\system32\Dllcache\mmcndmgr.dll
regsvr32 /s %windir%\system32\shdocvw.dll
regsvr32 /s %windir%\system32\Dllcache\shdocvw.dll

Save this file as ExplorerFix.cmd, and I recommend placing it (or a shortcut to it) on your desktop. When Windows Explorer won't open or crashes whenever you try to open something, double click on ExplorerFix.cmd, and most of the time it corrects that issue.

XP service pack 2 implements a new feature of memory protection against viruses, this stops code being modified that is listed as "Non Execute" in the memory "NX"

now for some people and future systems this isnt a problem, this technology requires a instruction set on the CPU to work properly, otherwise it is done in softeware emulation. Since the only chips so far that has the NX instructions are the AMD64 chips and some P4's i think.
This causes problems on systems running cpu's without the NX instruction set and therfore causes the crash problem we experience.

DEP is the m$ tag line for the NX technology. by default it is turned on and is set to protecting all windows system programs and services. I've only noticed this problem on sp2 upgrades without the hardware NX support, so far clean installs with sp2 and streamlined installations have had no problems. not too sure why this occurs must be how the os has delt with programs in the past and sp2 changes it and ergo the crash.

but since right click is a system command this poses a puzzler

in all sense and purposes, the threat this prevents or helps to prevent isnt live in the world atm its very deep down underground.

for the home user, not having a chip with NX causes an extreme system resource hog and slows down the system / programs and causes more crashes. but thank something your using XP cos if this crash occured in 9x then you would have a blue screen everytime you wanted to do anything, admitidly you would anyway LOL but thats not the point.

Turning off the DEP will stop the crashes and will make ur system almost 99% as fast as it was without sp2. DEP is not needed atm, with a good AV and firewall, you are safe. DEP will be critical in a few years when NX enabled chips are mainstream.

OK, thanks. My h/w does not have this implemented so turned off DEP via boot.ini (confirmed in My Computer/Properties/Advanced/Settings). Watching with interest to see results.

hey i was wondering if the shellexview or changing the NX thing to alwaysoff will work in my situation.

I have a thread started but i don't seem to be getting any response. what happens is, whenever i open a folder with movie files, my explorer.exe crashes. i can open the movie files through different programs such as wmp or winamp but if i actually open up the folders through My documents or something, explorer.exe will crash.

will the solutions posted on this thread help me?

i would start with the shell thing, you can disable all non microsoft stuff and see if that works. and you can always turn them back on later. this is an invaluable tool. everyone should know how to use it.

[custardjim]

Downloaded the Shellexview and disabled all non-MS stuff. Nothing.

Edited the boot ini. file to make the NX 'alwaysoff." Nothing.

Every time I open the 'my video' folder the little MS security feature activates and blocks something (not sure if this is related); then explorer gives me this error message:

AppName: explorer.exe AppVer: 6.0.2900.2180 ModName: mpeg2decoder.ax
ModVer: 1.0.0.67 Offset: 0000e350

Then it shuts down explorer.

I've tried renaming the files to shorter names, nothing seems to help. There is one large mpeg that I created using Roxio software, and I suspect this is the problem,but the mpeg is no larger than many other files I have.

Any ideas?

[custardjim]

I deleted the mpeg created by the Roxio software and now I can open the folder without crashing Explorer.

Any idea what the heck is going on? Why would the mpeg crash explorer just because it was made using Roxio?

thanks

Hey !! Skip all the others - this is the one that fixes the problem.

It's not SP2, cuz I have not installed it yet.

Certain badly behaved programs can do it and the one that did it to me is not likely the one that did it for others. For reference, for me it was a freeware zipper, TugZip. When I disabled its context menu, the problem was fixed. Tugzip still works just fine but I can't access it from right-clicks. No problem though - I just use the start menu.

THanks Lespaton, your solution worked perfectly.

The culprit for me was a spyware killer program Antiy Ghostbusters

Hi
Made the change just as instructed, no improvement at after rebooting. Any other ideas.
