If you are deploying a lot of Vista machines in your organization, you may want to consider updating the OEM information that gets shown in the System Properties. This adds a nice level of customization that makes it easy for your users to know where to find support, what hours support is available... and it's just a fun thing to do to lighten up the corporate drudgery. To do it, you need edit the registry.

Open the registry editor and navigate to this section: HKEY_LOCAL_MACHINE + SOFTWARE + Microsoft + Windows + CurrentVersion + OEMInformation. Once you get there, you'll find fields that allow you to update the following:

- Logo (this needs to be a bitmap file)
- Manufacturer
- SupportHours
- SupportPhone
- SupportURL

Using these fields, you can add a nice level of customization to the System Properties panel for your organization.
