after a week try and try to fix windows 8 update/upgrade to windows 8.1, finally I'm success to do that.
the first time i try to install windows 8.1 after getting notification from windows everything is going fine, downloading, install, getting PC Ready, and then I'm stuck at 82% (Getting information). from that, the update is failed with first code error is 0x80070002.
and then I try to fix it by run windows update diagnostic tools from microsoft, but still the same result I found.
so I decide to do a little experiment with the tutor from all website to solve this problem, (Actually, most of the tutorial to fix this problem is not working for me).
here is the step I make to fix those error and update my win 8 to win 8.1.
1. I created new user profile with microsoft account (@Hotmail.com) and then give it as an administrator. (If you don't know you can
follow this step)
2. I run windows update diagnostic once again. (Use default windows update diagnostic in the control panel -> troubleshouting ->under SYSTEM AND SECURITY -> Fix Problem with windows update
3. now after after "fix problem with windows update" task is open in new windows, you should run it as an administrator by click advanced in the left bottom. and the click next.
4. I found several problem and then windows fix it for me.
5. I clean the cache for windows apps store by press win + R (Open run) and then type WSReset.exe
6. and I try to run windows update again through windows apps store. but this not fix my problem, with the second code error show up 0x80070004.
7. frustrating and confused, I almost go to reset my windows 8. but I know there must be another way to fix this problem.
