Iertutil.dll

because nothing on my start menu is to click on.

try to use the computer to someone else, go to dll-files.com and research of this file (iertutil.dll), download the file will be compressed, decompressed, there will be 2 files it contains, copy the iertutil. dll copy on a USB drive (flash drive), or whatever you want, and then a file in your computer in c: \ windows \ system32.

That is it.
