To check the internet connection;
  • In the search box on task bar, enter network troubleshooter, select Identify and repair network problems. Now follow the on-screen instructions to fix the issues with network.
If the network troubleshooter does not have any problem, then try to restart your PC, which will fix the issue.
Error 0xC004E003:
A third-party software that changed the system files should be blamed in such situation. Windows activation needs the system files and changing them will hinder activation.
You need to restore your PC's system files back to an earlier point. However, doing so will remove the software that was installed, without affecting your personal files.
Error 0x80004005- 'Unspecified error'
If this error message shows up, go to Start>> Settings>> Update & security>> Activation>> selectActivate Windows to manually perform the Windows activation.
If that fails to work, restart you PC and then perform the activation.

Apple threatened to ban Uber

Apple CEO Tim Cook threatened to remove Uber from the App Store in early 2015, amid revelations that the ride sharing service had violated iOS privacy rules, according to the New York Times. Uber had reportedly assigned permanent IDs to iPhones, allowing the company to track users even after the Uber app was deleted or an iPhone was wiped.

Controversial tech exec Travis Kalanick was forced into a face-off with Tim Cook, a new profile of the Uber founder claims, after Apple discovered the ridesharing app had flouted privacy rules. Kalanick’s company has repeatedly made headlines over the past year for a number of reasons, ranging from frustrated drivers, arguments with city administrators and legacy cab firms, over-ambitious autonomous car testing, and allegations of harassment in the workplace. Indeed, Kalanick’s ambition almost saw him lose his entire iPhone audience. The degree to which Kalanick was willing to push his company to the brink is made clear in a new profile of the entre…

How to Remove Windows Genuine Advantage Notifications

The validation test can be failed due to being sold a pirated (non-genuine) copy of XP, or because you have changed your XP product key to a software-generated key, or sometimes it just happens for no reason at all. The failed validation installs three types of notifications on your computer: one on the log in screen, one log in timer, and one balloon. It also stops updates from Microsoft and disables your ability to install IE7 and Windows Media Player 11. This solution can get rid of all three notifications, even though you will still not be able to update through Windows Update. You will not be able to download things from Microsoft that requires a valid license either. EditSteps
Delete Method 1 If you have only just installed Windows Genuine Advantage notifications, simply using the system restore function will remove the program. Then refuse to accept the WGA update next tim…
