Sometimes when we customize a folder and upon restarting we realize that the changes haven’t been saved. In some cases the settings work for few days and then XP forgets it. Ever wondered why this happens? Well, this is due to that fact that Windows XP remembers the settings for only 400 folders, by default. When you customize more folders the old settings are lost. To prevent Windows XP forgetting the folder customization, we can increase the limit till 8000 (which is the upper limit). Set the BagMRU Size to 6000 (Decimal) in the following registry keys:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsShell HKEY_CURRENT_USERSoftwareMicrosoftWindowsShellNoRoam Let me remind you that the value that we set is in Decimal and not hex.
