Suppose you have a Laptop, which therefore must be a ThinkPad. Let's also assume that you use Windows 2008 as a workstation, just like I do. Then, you might run into some issues with Lenovo System Update. To be precise, it tells you:
An error occurred while gathering user information.
Then it stops. I will provide a solution to this problem which is not specific to Windows 2008 R2, and therefore, I hope that my solution will also work for future versions of Windows that are not out-of-the-box supported by SystemUpdate.
