Neem's right about Windows corruption--and that corruption can also be caused by virus/malware attack!
Have you used your built-in AV to scan for and remove viruses? If not, you should do this next if neem's suggestions don't get your IE11 working again. After that, you should also scan for and remove spyware viruses, which over 80% of failed computers have that I see in my repair shop. Download the free
MALWAREBYTES from
malwarebytes.org and scan/remove all spyware viruses found. Retest your IE11. If fixed, you had 1 or more viruses and or spyware viruses that scrambled your IE11, one of the most commonly attacked components of Windows10. And you're all set to go!
If that fails to fix the problem, you should know that many viruses when removed, have code in them that purposely erases windows systems files or corrupts them or both!
Therefore, the easiest way to correct this problem is to attempt to use the built-in Windows utility,
SYSTEM RESTORE and
UNDO any or all of these changes made by the virus upon forced removal. This will restore your IE11 to working order about 60% of the time.
The Stop error you have is quite common in W10; there are several variants of this; but usually it means your W10 is gone! And the only way to fix it is to repair Windows using software tools such as in-place upgrade, boot repair, or windows reinstallation using the Microsoft MCT tool or factory Recovery Discs for W10 which you most likely don't have on that computer since you upgraded it from W7.
If Restore fails to fix the problem, you might have coincidental hardware failure; on older computers running Win7 which you upgraded to W10 from; this happens all the time, as Win7 computers are now 7 years old going on 8 years old in 2017. Desktop hard drives are only designed to last for 3 years--laptop hard drives are only designed for 2 years!
If you are the original owner of your computer and you've never replaced the hard drive in that computer yourself or paid someone to replace it for you, there's a
95% chance it's failing or failed completely! If this is the case, continuing to apply software solutions to a computer with a broken hardware component is a complete waste of time.
**NO SOFTWARE ON THE PLANET CAN REPAIR BROKEN HARDWARE!!!***
If you get to this point in this Post, you need to consider testing your hardware yourself (DIY), or paying a local licensed Computer Pro to do this for you. If you decide to do this yourself, I've written an excellent Troubleshooting Guide here that will take you through hardware testing of your computer or laptop step-by-step, and provide detailed software repairs that will produce a fix 90% of the time if you are willing to spend the time and effort to follow the Guide's instructions. This can take 2-3 days to 1 week or more however, so if you are not the patient type, you may wish to pay a professional to do this for you. If you don't have the patience or the money to do so, try using my Guide.

And remember if you get stuck along the way, feel free to post back any questions you have. There are no stupid questions in computer repair. And we are here 24x7x365--so if I don't get back to you right away, Neem or one of the other volunteers will surely do so.
Best of luck,
