Start Internet Explorer. On the Tools menu, click Internet Options.
Under the Advanced tab, click Reset. In the dialog box Reset
Internet Explorer Settings, click Reset to confirm your choice.
If this doesn't work try the following:
Exit out of Internet Explorer. type Ctrl-Esc to bring up search bar,
and type "cmd". Right click and choose "run as administrator". When
the command window opens type "regsvr32 oleacc.dll". Open Internet
Explorer back up and Ctrl-F should work fine.
Most of this is for IE9 but it should apply to IE 8... You could just update to IE 10 and not be 2 versions behind? :)

then choose your language and then your version of Vista (possibly you
were getting the wrong version in WU or from another site if that's
how you upgraded). When it prompts to download, select "Save As" and
browse to your Desktop and save it there.
Once the download is complete, go to your desktop and the installation
program icon should be there. Right click on it and click on Run as
Administrator (even if you are already logged in as an administrator)
and it should proceed with the installation (this process sometimes
helps with installations). Reboot when done and when you return,
hopefully IE9 will be installed and working.
If that doesn't work, check out the following article on
troubleshooting IE9 installation problems:
