Which updates is it stuck trying to install? If its the .net framework ones then you could always uninstall .net framework 4 (via programs and features), reboot, then install .net 4.5.1 from here
updates:
cumulative security update for internet explorer 11 for windows 7 for x64-based systems (kb2898785)
security update for windows 7 for x64-based systems (kb2887069)

kb2887069 has been causing no end of problems and really should have been recalled by Microsoft. Try unticking this one and see if the others go on ok. You can also try googling the kb numbers and download the updates directly off the microsoft website to see if any of the stuck ones will go on when you run them manually.

OP, try the fix below first:

It's also worth checking the time and date on your PC.
The normal Google would have been so much quicker.
Have you done anything mentioned above?
Do you mean the Microsoft Fixit?
If you don't explain clearly what you've tried there is little hope of helping you to solve this problem, sorry.
