To work around this problem, create a BagMRU Size DWORD value in both of the following registry keys, and then set the value data for both values to the number of folders that you want Windows to remember the settings for. For example, for Windows to remember the settings for 5000 local folders and 5000 network folders, set both values to 5000.

You must create the new value for the following registry keys:Important You may have to adjust the BagMRU Size values for your specific situation. If you increase the BagMRU Size values, the information that is stored in the registry increases. When you use roaming user profiles, registry information is copied to a server when you log off and copied to your local computer when you log on. Therefore, you may have performance issues if you increase the BagMRU Size values for roaming user profiles.
