Windows XP was designed to remember the settings for 400 folders by default. This is a very common problem among users as this setting is easily exceeded. In order to make Windows XP remember more folder settings a simple tweak in the Windows Registry is required. As always, be sure to make a backup copy before making any changes in the registry.
Increase Folder View Setting:
1. Go to Start>> Run. Type in: regedit [Enter] or click OK.
2. Navigate to the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell
3. Click once on the "Shell" entry to view its contents in the right pane.
4. Double click the "BagMRU Size" entry.
5. Tick the "Base" entry titled: Decimal, then in the "Value data:" box, increase the amount to 8000 (see Fig#1).
6. Click OK
7. Repeat the steps above for the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam
8. Exit the Windows Registry.

Edit Dword Value for BagMRU Size
Windows will now remember 8000 folders instead of 400. 8000 is the maximum number of folders that Windows XP will remember. No performance issues should be noticed after this change.
