A bit late to comment, perhaps you found a solution already.
Have you tried Linux?
I never use Windows for Internet browsing anymore.
The best part, it can be run from a USB stick, independently from your windows installation.
There are many different distributions of Linux to try, the most user friendly in my experience is Mint
The user guide is here.
Three basic steps to get started.
Download a Mint ISO image ( I prefer Mate, but any version should work)
Copy the Image to an unused USB stick (2GB minimum)
Boot from the USB stick.
