Unable to complete update
My sister 's PC operating system is Windows XP. Installation is successful but update takes hours without completion. I have followed troubleshooting guideline ie 1)disconnect internet, Run supporttool.exe, 2)under Uninstall, stop all components, 3)after a minute, option 2 delete last update and option 3 delete proxy, 4)restart. However after restart, when internet auto connect, it shows Start Protection then Install update but keep running without end. This is unacceptable and ridiculous! Any fix?
