Microsoft has opened a transparency centre in Brussels to work on relations and information sharing with local governments which will include sharing the source code of its software to prove their are no backdoors.
The launch comes at a time when governments have a number of questions for technology firms concerning surveillance, competition and security.
"Governments around the world are under increased and increasing pressure to protect their citizens and critical assets from cyber attack," said Matt Thomlinson, vice president for Microsoft Security, in a blog post.
"As part of this investment, I'm excited to announce the opening of the Microsoft Transparency Centre in Brussels, the latest step in the commitment we made to enhance the transparency of our software code and continue building trust with governments around the world."
The opening will bring Microsoft and its source code closer to concerned governments, and offer an opportunity to assess it for the kind of backdoors that can be exploited by the surveillance and hacking communities.
"As noted by the European Commission's vice president for the Digital Single Market, Andrus Ansip, trust is the essential ingredient for enabling the completion of the Digital Single Market, Europe's ambitious plan to drive growth and competitiveness in the region through the use of digital technologies," Thomlinson added.
"Only by increasing confidence in the digital solutions which have the potential to catalyse whole economies can Europe ensure that every citizen, business and government feels the benefits of the digital revolution.
"And we hope today's announcement can help bring us one step further towards achieving this goal."
Microsoft opened its first transparency office in the US last year, but this is the company's first in Europe. It arrives when technology firms, including Microsoft and Google, are resisting efforts from governments to weaken security.
Free software advocate and pioneer Richard Stallman said this month that Microsoft's software is essentially malware.
"What kinds of programs constitute malware? Operating systems, first of all. Windows snoops on users, shackles users and, on mobiles, censors apps," he wrote.
"It also has a universal backdoor that allows Microsoft to remotely impose software changes. Microsoft sabotages Windows users by showing security holes to the National Security Agency before fixing them."
