I am dual-booting Windows 7 and Windows 8 on the same PC.
You can use any version of Internet Explorer on Windows 7 and the text will be clear.
I am running IE 10 on Windows 7 with no blurriness at all.
It is only a problem in Windows 8.
The only program I could get not get clear text in on Windows 7 was MS Office 2013.
It was almost as bad running on Windows 7 as it was on Windows 8.
So I reverted back to Office 2010.
