After the folder Software Distribution has been renamed or deleted, the service Windows update can be started again by right clicking it and to choose for Start.
You are also able to download updated drivers for the hardware.) The folder $hf_mig$ is the only exception to this rule.It is advised to keep this folder as it is, although removing it doesn't result in problems.After you installed the high priority critical updates, restart Windows and visit the Windows Update website again.These updates can be massive, especially if service pack 3 is not installed yet.
