apparently when hit ok ,its try to run debug with Dr.watson and error reporting so i disable dr.watson and error reporting service after that the cancel button disappear and there is just ok .
im monitored process with "process monitor" and find out its coming from csrss.exe and try to pinging some address ,then i replace csrss.exe , winsrc.dll and crsrsv.dll in recovery consol but its appear again .
also i scan the windows with node32 SysInspector and findout Crsss.exe have some problem ,but i have no idea to solve the problem.
thanks for your attention
