Windows Store Crashes

Though 512 is a big extensive variety and I do not think anyone would pin that many applications or applications to the Begin option, it is still a known problem in Ms ms microsoft windows 10 that if you go for more than 512 applications, they will appear reduced from the Begin option. Given that the extensive variety of applications pinned on Begin option is less than 512, the app flooring surfaces areas will be identifiable efficiently. If you combination the extensive variety, the Begin option is dreadful.

Microsoft has details on this and they are obviously trying to eliminate the cap.
So far, upgrade to #Windows10 has been pretty smooth on 5 year old PC except I can’t use Cortana or install apps from the Windows store. — CheckedShirtMatt (@ec1matt) July 29, 2015

There is no fix on the issue but it has been notified to Windows team. I am hoping the issue will be fixed soon. But meanwhile you can see point 3 of Windows 10 Guru Fixes.
