Using Chrome-Do I need to Update Internet Explorer version?

I see that in January 2016, if I don't have the latest version of IE (which in my case is IE11) installed on my Windows 7 64-bit machine, I won't receive any further IE updates. I have used Chrome as my browser for years now but I do faithfully install the IE updates as apparently even if you don't use IE, it has deep roots into the operating system. Anyway - my question is this.....should I update to IE11? I think my current version is IE8. Or should I attempt to block IE on my system? I gather it's pretty much impossible to totally remove it.
Any help would be most appreciated!

Thank you Swifty for the reply. From what I've read, it appears the best way for me to update to version 11 would be from the hidden update in my "Windows Update" page? I have both versions 10 and 11 hidden so would just download and install Version 11.

Thank you Layback Bear and Swifty for your help. I wound up going through Windows Update and all appears to be well.
Many thanks for your responses!
