Windows 8 has a lot in common with windows 7 except the startscreen tiles and the abundant windows 8 store apps. Since i was already using windows 7 i decided to upgrade my existing installation instead of making a fresh install. This saved me the hassle of setting everything up.
My computer successfully upgraded to windows 8 and i loved the new windows startscreen tiles but i noticed that the windows 8 app store not working. When the app store tile was clicked it just showed the windows 8 store icon and nothing opened up.
If the windows 8 store is not working for you too then first make sure your internet connectivity is good, if still it doesnt open up then you will have to follow the solution below. Note that the windows 8 store access problem arises only when you perform a windows 8 upgrade from previous version of windows.
Windows 8 Store Not Working? – The Solution
After spending some time with the microsoft support the conclusion came out that it was the antivirus program due to which windows 8 store is unable to open. The tech support representative said that this was a known issue with windows 8 and they are working on this windows 8 store fix which should be out soon.
In the meanwhile the quick solution is to uninstall the existing antivirus program from your computer and reinstall it. I was using the Kaspersky Internet Security 2013, so i completely uninstalled & installed it again and i was able to access the windows 8 store. I can now browse & install apps from the windows 8 store.
