doPatching.vbs

Obviously, patch management can be implemented with Software Update Server (SUS), but this requires client configuration through Active Directory. Some systems, such as Windows 98, can not be configured via Group Policy, and thus can not be configured to use SUS. So we need workarounds : download patches etc (e.g. from Windows Update Catalogue, save them to a network share, and have workstations execute the downloaded patches, security updates and service packs.

One major flaw : it's not fully automatic : each patch will require confirtmation from the user to be executed. We may have to look in to silent software installation techniques to work around this.
