My Windows XP home downloaded and installed a security update (KB925902), then i had to restart my computer. After that the problem occurred: every time i turn on my computer, i get the error message with the following text on the title bar: “RTHDCPL.EXE - Illegal system DLL relocation”. And here is the message:
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.
I uninstalled Realtek High Definition Audio driver. after that the message did not appear after bootup. Then i reinstalled the sound drivers again and the error message above appeared again after every bootup. And i cannot open the Realtek HD Sound Effect Manager. Then i restored my system back to the point where this security update was not installed yet. Everything was OK until the windows installed this update again. and again i got this error message. Can i blame Microsoft? Or there is something wrong in my system? Please advice.
