The message "Access is Denied" is a popup window. That is all that it says. Then to get rid of the message, you click "OK". Behind the popup it says"SP3 did not successfully update your computer". Then it begins to uninstall and restart my computer.
I download the SP3 to my computer. Then doubleclick on it and it starts to install. It runs for a long period of time. It says it reads my configuration, then begins installing files. Then after a long period of time, the message "Access is Denied" pops up.
The SP3 is from Windows download @ Microsoft.com.
My version of Windows is legitimate (genuine).
