I have a Dell Laptop, running Windows XP Home edition. On startup, I always get this message "Windows System Error - Object Name Already Exists" The message window has an "OK" button and while it doesn't appear to affect the operation of the machine, it is an absolute annoyance.
Using MSCONFIG, I have stopped all startup programs and still I get the message. Also using MSCONFIG, I have stopped most processes and still I get the message.
There is an entry in the Event Log that may be connected. At each bootup, the following error is reported "The WinDriver service failed to start due to the following error: Cannot create a file when that file already exists"
Oh, and btw, yesterday I reinstalled (using the upgrade option) WinXP. Still there.
