I don't think many Windows 7 users are going to want pre-release software, which is what IE10 for Windows 7 is. The only advantage I've seen for it is touch screen support, and most of us don't have those either. What motivated you to try it?
I installed the IE 10 browser and after I re-started my machine, it acted as it did when it was brand new (I just bought this HP machine w/Windows 7 Ultimate, a 16G memory and a 1TB hard drive). At first, I thought I lost everything somehow but I doublechecked and all my programs, etc. were still there. I then re-started it and it started normally again (fortunately). Anyone else have their system react like this?
