That has zero to do with bios update. Open services.msc - Click Start > type "services.msc" in the Start search box and then hit ENTER. Now, check for Windows Store, if the service is not running then click on it to run. Now check if Windows Store is opening or not. If it is still showing a blank screen, then you have to follow the next step. In most of such cases, Clearing the cache can fix the problem. You can try clearing Windows Store cache by Pressing Windows Key + R to open Run, after it opens, type - "wsreset.exe" command and hit OK. Now, you will see a blank Command Prompt window that will automatically close in 10 seconds approximately. After it closes, Windows Store should open automatically. If not. Open Settings and then click on Troubleshooting. Now, click on Windows Update Troubleshooter and run it. A new window will open up, wherein you have to select "Try troubleshooting as an administrator" and then click "Next." Wait for some time and let the Troubleshooter complete its scan. After its completion, restart your PC and open Windows Store again. It should open now and show all the apps and content.
First of all I have been having problems updating my R11 Bios from 1.0.3 to 1.0.4 to 1.0.5 since March every time I try then go to sys info it’s still at 1.0.3 so I gave up cause I’m so scared of bios updates. Yesterday I had a windows update restart message and looked on the list of updates and Alienware bios Version 1.0.5 was on it, took me about 15-20 mins to decide Go for it so I did. After restart I go to system info. and what do ya know bios version is 1.0.5 I was like so confused but very happy to get that out of the way. I am know totally updated on everything on this rig.  Cheers
Aurora R11, Bios update 1.0.5 installed
