Microsoft has averted a potential antitrust battle over security features in Windows 10, agreeing to make changes to the operating system sought by Russian anti-virus software builder Kaspersky Lab.

Kaspersky had filed antitrust complaints in Russia last year, and in the European Union in June, accusing Microsoft of giving priority to its own security software and making it more difficult to run Kaspersky’s tools on Windows 10.

Early Thursday in Europe, the companies announced a truce in synchronized blog posts, an agreement that follows a meeting between the two last month.

Kaspersky said it would withdraw its antitrust complaints after changes Microsoft had agreed to roll out in its operating system, which runs on most of the world’s personal computers.

“We are grateful Microsoft is addressing these issues completely,” said Kaspersky’s blog post, attributed to Andrei Mochola, vice president of consumer products.

Mochola said Microsoft had agreed to give developers like Kaspersky more time to tweak their software in response to Windows 10 updates. Previously, such automatic updates could also automatically disable Kaspersky and other security software in favor of Microsoft’s alternatives.

Additionally, Windows 10 will allow security companies to show their own notifications, including prompts to update software to the latest version, in the operating system’s notification panel.

In Microsoft’s blog post, the company said: “We appreciate the feedback and continued dialogue with our partners and are pleased to have found common ground with Kaspersky Lab on the complaints raised in Russia and Europe.”
