If you are running Windows XP SP2 (including Media Center and Tablet Edition), and you have applied the Microsoft updates 925902 (MS07-017) and security update 928843 (MS07-008), and you are using Realtek audio components on your system, you may receive this error message when trying to use ElsterFormular, Realtek HD Audio Control Panel, TUGZip, and CD-Tag.

{application name} - Illegal System DLL Relocation

The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the DLL C:\Windows\System32\Hhctrl.ocx occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL.

DLL Error: esent.dll and wuauclt.exe - Access violations and other errors after user logs in

A friend had me check out his ailing Windows XP Home notebook computer last night. Every time he booted the computer, it would display an endless stream of error messages about wuauclt.exe having caused an access violation. This message would reappear every 30 seconds or so.

Microsoft has a hotfix (see 'related links', below) that is supposed to address this problem, but I was unable to install the hotfix - the system would display an error message saying that it could not verify the system configuration, and therefore could not install the hotfix.
