I got an error message everytime i shut down my pc. i got windows xp sp2. its very irrittating to see that error message.

i got this error message -
"dwwin.dll failed to initialize because application is shutting down"

who can advise me on how to fix this problem or remove that error.

I'm guessing that the "dwwin.dll" error message is the result of some sort of fault occuring at shutdown. When Error Reporting attempts to report the error, it can't because the machine is shutting down. To fix the shut down problem try eliminating unnecessary start up programs from running in the background. That way, there aren't as many programs to cause conflicts at shut down.

How To Clean Unwanted Files From The Hard Drive
This may get a little long, so you might want to print it out.

Click on Start-Search-Files or Folders, type "*.tmp" (without the quotes), click on the "Search" button. Once all the files show up in the box, and there can be quite a few some times, click on "Edit" in the upper left of the window, choose "Select All" and all the files will be highlighted. Then click on "File", choose "Delete" and the files will be deleted. You can safely delete .tmp files, as they are only temporary files and are placed by Windows when using various programs.

Next, do the same procedure for .chk files that have been placed there by the Scandisk program, or others, after a bad start up. Click on Start-Search-Files or Folders, type "*.chk" (without the quotes), click on "Search" button. If any files are found, delete them using the "Edit, Select All, File, Delete" method from above.

Next, you need to clean out all files from these folders. C\Windows\Cookies, C\Windows\History, C\Windows\Temp, and C\Windows\Temporary Internet Files. (On Windows 2000/XP, the folder locations will be slightly different...for example, the "Cookies" folder is located at "C\Documents and Settings\Yourusername\Local Settings\Cookies". Each user will have a separate folder for each of the above and will need to be cleaned out separately.) Start by doing this. After logging on as an "adminstrator" if using Win2000/XP, or logging on normally if using Win9.x/ME, Click on Start-Settings-Control Panel, double click on the Internet Options icon. When that loads, make sure you're viewing the "General" tab, then click on the "Delete Files" button in the "Temporary Internet Files" section. When the little box pops up, place a CHECK mark in the "Delete all offline content", then click on OK. Now click on the "Settings" button in the "Temporary Internet Files" section and change the number on the "Amount of disk space to use" section to a number of 5. (Some default settings allow for hundreds of mb in this area) Click on Ok, then "Apply" if its not grayed out, then Ok again.

Next, RIGHT click on Start, choose "Explore" from the menu, then looking on the left side of the window that loads, navigate to the folders mentioned above, then double click on the folder. Next, double click on the "Cookies" folder. Delete all the files within this folder by using the "Edit, Select All, File, Delete" method. (BE AWARE...some cookies "remember" your log in passwords at various websites. This will remove those and you'll need to log in the next time you visit that site. If you choose, you can save those cookies with remembered passwords.) Next, double click on the "History" folder and delete all files from each one of the days listed. Next, double click on the "Temporary Internet Files" folder and remove all remaining files from that folder. (You'll notice that the "index.dat" file probably can't be deleted. That's ok, leave it there. It can be removed from a command prompt, but for now, ignore it.)

At this time, empty your Recycle Bin of all files.

Next, double click on the "Temp" folder within "Windows", (or within the "Local Settings" folder in Win2000/XP). There may be a bunch of files in this folder that were placed there by various programs, or program installations and uninstallations. Normally, these all should be safe to delete, UNLESS you have "saved" any personal documents here. Just to be careful, highlight a small group of files and delete them to the Recycle Bin. Restart the computer, run the programs, and generally test to make sure that any necessary files haven't been removed. If you don't experience any problems, and you shouldn't, then remove that bunch from the Recycle Bin, then choose another group of files from the Temp folder and delete them to the Recycle Bin.

After removing all the above files, and if you’re using WinMe or XP, it's possible to gain extra space by temporarily disable your "System Restore”. Although this should be done only when the machine is running good and you don't think you'll have a need for using SR, the procedure will decrease the ever-increasing bloat/size of System Restore. After disabling SR, restart the computer again, then “re-enable” System Restore by UNCHECKING the box mentioned above. At this time run Scandisk and Defrag to correct and align the file system to its optimum.

Or just use some error fixing tool.. Like Tune-Up Utillities...

@animex - i will try this method.

Global360, try to run msconfig. And select a clean startup and check whether the problem still exist or not. If not, then enable one program to startup and slowly identify which are the application that cause the problem.
