On Wednesday, Shares of Microsoft Corporation (NASDAQ:MSFT), lost -0.42% to $56.31.

For the PC market, 2015 was one of the worst years. Global PC shipments suffered their steepest fall in calendar 2Q15 since 2013. The PC market that was eagerly anticipating Microsoft’s (MSFT) Windows 10 launch failed to witness any uplift, according to Market Realist.

Microsoft then joined hands with its peers Intel (INTC), HP (HPQ), Dell, and Lenovo (LNVGY) to create an ad campaign to bring some hope to the PC market.

Microsoft’s Windows 10, which was launched as a successor to Windows 8 on July 29, 2015, is doing well.

In its fiscal 1Q16 earnings release, Microsoft’s chief executive officer Satya Nadella stated that there were “more than 110 million monthly active devices running Windows 10.” He went on to state that Windows 10 adoption is “three times that of Windows 7 over the same time period after launch.” However, as it is a free upgrade, its performance can hardly be described as stunning.

Gartner’s IT analysts share the opinion of the above-mentioned statement. Gartner anticipates that 50% of enterprises are likely to start deployment of Windows 10 by January 2017 in anticipation of concluding their migrations in 2019. Microsoft has declared that it will pull support for the Windows 7 OS in January 2020, which will prompt many businesses to start pilot programs in the first half of 2016. Windows 10’s “strong compatibility with Windows 7 applications and devices” will complement this migration. Market Realist Reports

Shares of Twitter, Inc. (NYSE:TWTR), declined -1.07% to $22.23, during its last trading session.

Shares of Twitter were gaining by 1.6% to $22.83 on Wednesday morning as the social media company updated its rules for abusive behavior and hateful content.

The San Francisco-based company outlined the changes in a blog post on Tuesday as it faces increasing criticism that it’s not doing enough to stop the Islamic State from using the platform for propaganda and recruitment purposes, Reuters reports.

“Twitter will not tolerate behavior intended to harass, intimidate, or use fear to silence another user’s voice…we will continue to take action on accounts that cross the line into abuse,” Megan Cristina, the company’s director of trust and safety, wrote in the post.

The blog post did not name the Islamic State or any other group and did not comprise any changes to the company’s strategy of enforcing the updated rules.

Twitter, Inc. operates as a global platform for public self-expression and conversation in real time. It offers various products and services for users, counting Twitter that allows users to create, distribute, and discover content; and Vine and video, a mobile application that enables users to create and distribute short looping videos.

Finally, Shares of Pfizer Inc. (NYSE:PFE), ended its last trade with -0.24% loss, and closed at $32.75.
