Hi Sar Psayin.
From your issue description, I understand that
“after installing the updates you are not able to boot to the desktop”. Please let me know if you are not facing this issue.
Method 1I would suggest you to perform startup repair using Windows 8 DVD.
a) Once you get the welcome screen of installation with the option “Install now”
b) Click on Repair your computer
c) On the next page click on Advanced Options
d) Now click on Troubleshoot
e) Lastly click on Startup repair and follow the on screen instructions
This may take 15 to 20 minutes to repair. Once completed try to login to your desktop
Note: If you have purchased Windows 8 online from Windows store but did not select the option to include a Windows 8 backup DVD, you may
use the Windows Order Summary page to purchase backup media and have it shipped to them.

Method 2
if the issue still persists, then I would suggest you to perform system restore from the same recovery console.
a. Press ‘Windows Key + r’
b. In the run window type ‘rstrui.exe’ and click on OK
c. Click on next in the System Restore windows
d. Now choose the restore point of your choice, and try to restore your computer back to earlier state.
If the issue persists, post your reply with results and questions asked as above. We are happy to assist you further with advanced troubleshooting steps!
