I want to update my WINDOWS 8 TO WINDOWS 8.1. But it doesn't updating. PLEASE HELP ME TO FIX THIS ERROR.

Question

SO HERE IT IS.
I ALREADY READ MANY STEPS, MANY TIPS ON HOW TO FIX MY PROBLEM IN MY WINDOWS. BUT I REALLY CAN'T FIX IT. I'm not professional in terms of Computer System. But I really want to upgrade my Operating System to Windows 8.1.
I really can't do it. 
The window store says that I need to upgrade the pending updates for my applications but when I click install all.
It's just pending. There's nothing happening. There's nothing installed. 
So I go to control panel then search the windows update.
There I click the Install Updates. I waited for 4 hours. But there's really nothing happening so I cancelled it.
Then here is what happened after that.
IT SAYS THAT code:80070003 windows update run into a problem then I clicked the "Get help with this error"
Then I run the troubleshooting
And then after that.
the troubleshooting has completed this is what it said.
Problems Found:
Service registration is missing or corrupt
Windows Update error 0x80070057 (2014-08-10-T-02_20_42P)
Problems Installing recent updates
So that's is.
I don't know what to do.
PLEASE HELP ME. :(

Thanks, but, using the "free" version of Reader, there is no opportunity to open nor import the xml data - the menu options do not exist - there is no import listed.
If we try to open the xml file directly, then we get an error - something to the effect of "unsupported file type, or the file is corrupted".
I just noticed in my Pro version that there is the command File ->Form Data ->Import Data to Form... command. Is this what you are referring to?
What do you recommend? Perhaps the easiest thing to do would be to purchase a few copies of Acrobat Pro for the reservations people to use? I was hoping that the free version of reader would do it, but perhaps not?
Thanks again,
Rob
