Windows 10 is one among the most popular operating system by Microsoft, It has been installed on millions of pc’s in just few days of its official launch. But Windows 10 is big controversy, As Windows 10 is almost spying on all of your activity and also Windows 10 has a right of disabling all of your pirated software.

According to GNU Operating System, Microsoft’s Software is big malware, As windows 10 updates itself without the permission of the owner. Windows 8 also has a backdoor which can remotely delete apps of users. German Government also warned its key entities to not to use windows 8.

There are also reports that Microsoft informs NSA about the bugs in its software before fixing them. Back in 1999, it was asserted that backdoors had been built into Windows:

A careless mistake by Microsoft programmers has revealed that special access codes prepared by the US National Security Agency have been secretly built into Windows. The NSA access system is built into every version of the Windows operating system now in use, except early releases of Windows 95 (and its predecessors). The discovery comes close on the heels of the revelations earlier this year that another US software giant, Lotus, had built an NSA “help information” trapdoor into its Notes system, and that security functions on other software systems had been deliberately crippled. 

Microsoft also owns Skype so back in 2012, there were discussions about whether Microsoft had changed Skype’s architecture in order to make snooping easier (Microsoft has a patent on this idea.) The recent leaks seems to confirm that those fears were well founded :

Microsoft Corp., the world’s largest software company, provides intelligence agencies with information about bugs in its popular software before it publicly releases a fix, according to two people familiar with the process. That information can be used to protect government computers and to access the computers of terrorists or military foes. – Bloomberg

Also Slate Points out :

There were many striking details in the Washington Post’s scoop about PRISM and its capabilities, but one part in particular stood out to me. The Post, citing a top-secret NSA PowerPoint slide, wrote that the agency has a specific “User’s Guide for PRISM Skype Collection” that outlines how it can eavesdrop on Skype “when one end of the call is a conventional telephone and for any combination of ‘audio, video, chat, and file transfers’ when Skype users connect by computer alone.” – Slate

Microsoft also stopped the support for windows XP, That means  Microsoft not only stopped technical support for the windows XP but also has stopped working on fixing the security related bugs. Here is what Microsoft  said :

After April 8, 2014, Microsoft will no longer provide security updates or technical support for Windows XP. Security updates patch vulnerabilities that may be exploited by malware and help keep users and their data safer. PCs running Windows XP after April 8, 2014, should not be considered to be protected, and it is important that you migrate to a current supported operating system – such as Windows 8.1 – so you can receive regular security updates to protect their computer from malicious attacks. 

Now lets talk about Windows 10, As Windows 10 comes with exciting new features and some of you will be thinking that as it a latest software your security and privacy will be highly reserved but thats totally wrong. Windows 10’s features are majority internet based so the latest software consumes a lot of internet. There are many settings in windows 10 to make sure your privacy is reserved but these controls don’t appear to be sufficient to completely prevent the operating system from going online and communicating with Microsoft’s servers. For Example,even with Cortana and searching the Web from the Start menu disabled, opening Start and typing will send a request to to request a file called threshold.appcache which appears to contain some Cortana information, even though Cortana is disabled. The request for this file appears to contain a random machine ID that persists across reboots.

With Windows 10 your Data is (ab)used.

Microsoft also renewed its Privacy Policy and Service Agreement. The new services agreement goes into effect on 1 August 2015.The new “privacy dashboard” is presented to give the users a possibility to control their data related to various products in a centralised manner. Microsoft’s deputy general counsel, Horacio Gutierrez, wrote in a blog post that Microsoft believes “that real transparency starts with straightforward terms and policies that people can clearly understand”. We copied and pasted the Microsoft Privacy Statement and the Services Agreement into a document editor and found that these “straightforward” terms are 22 and 23 pages long respectively. Summing up these 45 pages, one can say that Microsoft basically grants itself very broad rights to collect everything you do, say and write with and on your devices in order to sell more targeted advertising or to sell your data to third parties. The company appears to be granting itself the right to share your data either with your consent “or as necessary”.
