Make sure not to update the Windows Store on Windows 10 because I did that exact same thing and the update resulted in the store not reopening after the update. I thought it was due to the latest batch of Windows 10 Updates but then I update the windows store app before running an update check and the same result occured the store closed and when I tried to reopen it. It would act like it was going to open for about 2 seconds and then closes. Clicking on the store icon on the taskbar again and again to reopen the Windows store failed with the same result. After my tests it is not any of the windows 10 forced updates. I think microsoft botched the update for the Windows Store. The same thing happened on both of my windows 10 pcs. Contacted Microsoft and they were no help. So I reverted both PC's back to windows 8.1 and that's where they're going to stay. So I wanted to alert everyone to this issue. Don't update the Windows Store at least until microsoft fixes the problem. If you update the windows store app it results in the Store crashing and not working properly. Before the update to the Windows Store app the Windows Store worked perfectly on both of my PC's, after the update it refuses to run and won't work. So be careful when updating windows store apps.
