After updating Windows XP I am facing issue with some dll file. When I restart the pc after installing the update the error that I found on the screen is wxfw.dll. The error appear each time when I restart my system. But I cannot find the program which is causing the bug. I tried to perform system restore but that does not looks to be working well here. The restoration remains incomplete and I am getting the error constantly. Can anyone here help me to deal with the problem.
