After you perform System Restore in Windows Vista, you cannot install a Windows update, a hotfix, or a service pack. Additionally, you may receive the following error message:
This problem occurs because, after the System Restore is performed, the Common Log File System (CLFS) transaction logs may be left in an inconsistent state. When the CLFS transaction logs are in an inconsistent state, you may experience the problems that are described in the "Symptoms" section.
To resolve this problem, delete the .blf files and the .regtrans-ms files from the %Windir%\System32\SMI\Store\Machine folder.
