Microsoft admitted in late June that Windows 10 prompts to install a new version of anti-virus from third parties like Kaspersky after an update, but it disables the old version if it's not compatible.
Kaspersky first filed an antitrust complaint against Microsoft in its native Russian Federation last November, followed by complaints to the European Commission and the German Federal Cartel Office in July.
We are absolutely satisfied with the changes that will be implemented in the Windows 10 Fall Creators Update, and we will be taking all necessary steps to withdraw our claims and inform all regulatory bodies that we no longer have any matters for Microsoft to address.
Kaspersky complained that Microsoft automatically turned Windows Defender on when a 3rd party anti-virus subscription expired.
Kaspersky has been running a battle against Microsoft's free Windows Defender software since a year ago, and that included making an official complaint to the European, German and Russian antitrust authorities. The software maker will also provide better visibility of release schedules for Windows 10 updates, giving anti-virus vendors more time to test changes.More news: Marmite Could Prevent Miscarriage And Birth Defects, Says 'Breakthrough' Study

To placate Kaspersky, Microsoft will allow AV products to "use their own alerts and notifications to renew antivirus products before and after they have expired". "We look forward to our continued partnership with the industry". Microsoft will also let providers use their own alert and notification systems to let users know their licenses have expired - one of Kaspersky's key complaints.
Both companies simultaneously announced a resolution to almost a year of disputes that included Kaspersky alleging that Microsoft had erected unfair obstacles for independent security vendors on its Windows 10 operating system. The changes will affect Windows updates released globally. "This includes increasing the amount of time [antivirus] partners will have to review final builds before the next Windows 10 feature update is rolled out to customers", the company said.
"Kaspersky Lab and Microsoft have had a long history of cooperation in combatting cybersecurity threats across the world, and over the past months the companies conducted fruitful discussions about how antivirus services should operate in the Windows ecosystem to help ensure a safe environment for Windows users", Kaspersky Lab said in a statement.
Russia's Federal Antimonopoly service said in November 2016 that it had opened a case against Microsoft over an alleged abuse of market dominance. It claimed the company was using its dominant position with Windows "to fiercely promote its own - inferior - security software at the expense of users' previously self-chosen security solution".
Kaspersky had told regulators in Europe and Russian Federation that Microsoft was preventing antivirus software makers from competing on an equal footing with Microsoft's products.
