I am from Myanmar and I am now using Windows 8. The Windows 8 App Store is not supported in our country, but still I would like to open and download applications from it.
So, how can I access App Store?
This really is a matter of legality. Microsoft does not permit regions to access the app-store unless they are able to sell the apps legally in that country.
Reasons they cannot sell apps can include everything from issues with tax-collection, export fees and even laws against exporting of security technology. Asking us for instructions on how-to circumvent this goes against the Terms of Service for this site..
Try to use Proxy software like Ultrasulf. I'm also from Myanmar and by using Ultrasulf, I can now access Store and can download. But you need to have a good connection.
Good Luck Bro :)
