iertutil.dll ERROR due to Mocrosoft Updates

So... your PC asks for your login and then there's no desktop shown.
You wait, and wait and finally you see an error about IERTUTIL.DLL, or not-found or something.

You panic and think you've lost everything. NOT SO! 

DO NOT re-install windows.

You need to start your PC into DOS mode or just boot it with a Puppy Linux CD. Browse to the c:\windows\system32 folder and look for iertutil.dll and you will either not find it, or it will be zero bytes in size.

Find the c:\windows\system32\dllcache folder and look for the same file. Copy it to the c:\windows\system32 folder and overwrite the old file.

Re-boot your computer and it will show you a welcome screen and continue the update of Internet Explorer.

I'll bet you had the 'automatic updates' switched on. This problem is likely caused by IE being updated.

Pop quiz: What is delicate, brittle, transparent and when it breaks it shatters into a million pieces. GLASS. And what are Windows commonly made of... GLASS. Be careful or you could break your Windows. Get a good operating system and leave this all behind... Ubuntu Linux.

Enjoy.

    1. You can do a search for it (if it's in a different folder) or find a good copy on another machine. You will need to find that same version of the operating system.
