You can officially uninstall the IE11 with DISM. First run
DISM.exe /Online /English /Get-Features /Format:Table
(from a cmd.exe started as as admin) to get the name of all features. Remember what the correct name of the IE feature is.
DISM /Online /Disable-Feature /Featurename:Internet-Explorer-Optional-amd64 /Remove
(replace Internet-Explorer-Optional-amd64 with the name of the feature. I only have 8.0 here so I don't know if the name changed).
After a reboot, the IE is gone. If you activate the IE11 again in the
Turn Features on or off dialog in Control Panel, Windows downloads the removed files and installs IE11 again.
Also look at the first command if there is a skydrive package. If there is one, repeat the steps for Skydrive. If not, you can't safely remove it.
