Wireless Internet Not Connecting? Try Clearing Your DNS!

Overview

Your DNS cache stores the locations (IP addresses) of web servers that contain web pages which you have recently viewed. If the location of the web server changes before the entry in your DNS cache updates, you can no longer access the site.
If you encounter a large number of HTML 404 error codes, you may need to clear your DNS cache. After you clear your DNS cache, your computer will query nameservers for the new DNS information.

How to clear your DNS cache

    ipconfig /flushdns

Microsoft Adds QR Codes To The Windows 10 Blue Screen of Death

Microsoft is adding QR codes to its Blue Screen of Death (BSOD). It's the biggest change to the BSOD since the software maker removed a lot of crash details in Windows 8 and replaced them with a frowning face. The new QR codes are featured in the latest preview of Windows 10, which will debut this summer as the Anniversary Update.
Microsoft is using the QR codes to help support technicians identify error codes in the blue screens, and for Windows 10 users to quickly scan them from a phone to find support articles and assistance. BSOD's have often been complicated to understand, and at times difficult to use to identify the root cause of an issue, but this simplified approach leveraging QR codes could help Windows 10 users troubleshoot any system issues.
