This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To resolve this problem, reinitialize the cache of offline files. To do this, follow these steps:
Click Start, type regedit in the Start Search box, and then press Enter.
If you are prompted for an administrator password or for confirmation, type the password or click Continue.
Locate the following registry subkey, and then right-click it:
Point to New, and then click Key.
Type Parameters in the box.
Right-click Parameters, point to New, and then click DWORD (32-bit) Value.
Type FormatDatabase, and then press Enter.
Right-click FormatDatabase, and then click Modify.
In the Value data box, type 1, and then click OK.
Exit Registry Editor, and then restart the computer.
Make sure that files are synchronized before you add this registry entry. Otherwise, unsynchronized changes will be lost.
You can also automate the process of setting this registry value by using the Reg.exe command line tool. To do this, run the following command from an administrative command prompt:
REG ADD "HKLM\System\CurrentControlSet\Services\CSC\Parameters" /v FormatDatabase /t REG_DWORD /d 1 /f
- Make sure that files are synchronized before you add this registry entry. Otherwise, unsynchronized changes will be lost.
- The actual value of the new registry key is ignored.
- This registry change requires a restart. When the computer is restarting, the shell will re-initialize the CSC cache, and then delete the registry key if the registry entry exists.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
