yes. install ie7 frm microsoft.com, then reboot ur system. if the seup can't complete reinstall your Operating system.   zax's
If it is removed you will not be able to start Explorer.exe   Niklas Aldén
If it is removed, it will cause your system to not work. You can not pull up the start menu. Everything has to be done through task manager and you cannot do a restore. You have to remove internet explorer as a whole to repair your system.   Susan

C:\WINDOWS\system32\iertutil.dll  
This EXE that Microsoft Internet Explorer 8 produced tried to read my screen 8 times and hook my keyboard 2 times in less then a hour. The only reason I noticed this is because SnoopFree caught it. Not very nice of Microsoft to put something like this in their Internet Explorer.   Alex

iertutil.dll is located in an update for microsoft service pack 3. This update tried to install Internet Explorer 8 on my computer ( i assume becasue i had removed it and installed IE7 a month ago) and when the computer restarted i had no desktop GUI. I could only run from my XP OS's task manager 's run command. I can get online becasue i have fire fox as a second browser. However anything needing the explorer.exe and iexplorer.exe will nto run. at all. iertutil.dll is crap, IE8 is crap..i am sick of microsoft updates poisoning my OS onc ei get it stable and free of thier malware and viruses.  
Definitely critical for explorer.exe, mmc, and many other exectuables (anti-malware)  See also: Link   Lee

It isnt dangerous its just cpu greedy! follow these steps if you deleted or quaranteen it:- 1)let pc boot/and ur cursor is only thing visible on blue screen 2)press and hold ctrl/alt and delete(it should show few options) press few times if not! 3)start task manager:-goto top left in tsk mngr and click `file:new task(RUN)` 4)now in the`create new task option,click the `Browse file `button. before you search:click bottom bar and change from `programs to all files` click and navigate either to your desktop or C:\Program files..........and find your internet explorer browser shortcut. 5)enter in browser search bar `iertutil.dll` youll see a feww diff sites offering the download,probably a winzip/rar...... 6)goto your downloads file and copy the `iertutil.dll` ,using simular `task(run)option again navigate to C:\windows\system32` and paste it there....(if windows nt or 98 then go C:\windows\system or nt....paste 7)using `ctrl alt/delete` buttons again...get task manager up and top left click file(run task) .now just type into the box cmd 8)when the black Dos box appears....type `shutdown -r`(....without the `).. hopefully things be back to normal on reboot  See also: Link   william whizz connor
