i tried installing Windows service pack 2 on my laptop but half way through the installation said I hadn't got enough memory to complete. I couldn't stop the installation however and was forced to restart my laptop with a half installed service pack.
I had to re enter my activation key for windows and now when I log on, the desktop appears as normal and after about a minute I get an error message that reads:
windows will shutdown due to C://windowns/system32/isass.exe terminating unexpectedly. it then gives me a minute to close programs and an error code (2147483641)
I don't even have enough time to uninstall what was loaded.
