A common problem in the Windows XP\2003 is that; all of a sudden the folder view type for a particular folder(s) keeps reseting.
e.g.: The "My Documents" folder always opens in Thumbnail; even though you set it to List.

There are 3 possible solutions for this; follow any-one of them:

• This method is recommended for users who are not comfortable with the Windows Registry:
  Open Control Panel -> Folder Options.
  In the Folder Options Window; click the View tab, and now click on the Reset All Folders button.
  
  
• If the above method does'nt do the trick; follow the steps below:
  Open regedit (Start -> Run. Type: regedit. Press <enter>)
  Goto: HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam
  Delete the following keys:
  BagMRU
  Bags
