I damaged internet explorer using Revo Uninstaller.

Hi! I'm new and this is my first post. By some stupid reason I run Revo Uninstaller to unisntall Internet Explorer (I don´t remember what version) including the leftovers files. After this action the IE downgraded to version 9 and I can navigate with it, but
in windows 7 unisntall program list does not appear any version of internet explorer but in deactivate windows features appears intenet 10. I tried to uncheck it to uninstall (displaying some error message after cocluding the process) and then reinstall it after boot but internet 10 is still present and marked as checked (It was never unisntalled). I tried unsusccesfully to install the last version of internet explorer via windows update and by different scripts specially SFC / SCANNOW (This instruction says that was impossible to fix some damaged files).
My question is if there is some universal ironclad executable application that fix any problem related to IE, checking and repairing any damaged, deleted or corrupted system files and registers to finally install the IE lastest version. The main reason is that I can't get the Get Windows 10 Icon and after trying a lot of different ways to fix this problem I concluded the main reason I can not run the file GWX.exe has to do with Internet Explorer damaged system files. https://www.sevenforums.com/images/smilies/cry.gif
Thanks in advance!

Thank you Mr. Fireberd! I cannot use Windows and Revo System Restore because I deleted the restore points before. But after the launch of Windows 10, I suppose Microsoft will give us a free iso copy of Windows 10 installer.
I think it's the only solution. I have to be very patience downloading it because my internet connection is very slow and with constant interruptions. I'm going to mark this post as solved. Thanks again!
