First of all, if it has not already happened, do not let Windows Update
install v4.5.xxx.x of MSE. This version will create a nag which will
remind you that support for XP is over and your notification icon will
remain orange. If you have 4.5 installed you can uninstall MSE and
reinstall the last nag free version which is 4.4.304.0, if you can find
it somewhere - it was on MS site a few days back but they may have now
removed it and replaced it with the newer version. It may still be on
some thirs party site though.
