IE 8/9 ClearType problem

I installed IE9, but i开发者_如何学Got is impossible to turn off ClearType. So I removed IE9, and now in my IE8 I can't turn off ClearType, because checkbox is always disable:

Please help, what can I do?

If you are logged in as an Admin user and the option is still greyed out you could try amending this registry key manually:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\UseClearType REG_SZ no

I'm going to try to 'fix' IE9 for now but it's such a shame that MS insist on ClearType and are slowly removing any user preferences to change it...
