Microsoft Windows Дефендер тизимидаги хавфли заифликларни бартараф этди

Microsoft has identified two significant vulnerabilities in Windows Defender, specifically related to the Malware Protection Engine, which could allow denial-of-service attacks.

Avast Free Antivirus for US users: core features explained

Avast Free Antivirus is a free security application that provides essential malware protection and additional tools for Windows, macOS, Android, and iOS.

Microsoft confirms patching issues in restricted Windows networks

Microsoft has issued a service alert indicating that customers in restricted network environments may encounter Windows Update failures, specifically error code 0x80010002, after installing the January 2026 optional non-security preview updates. Affected devices might download the February monthly Windows security update but could struggle with updates released in March and beyond due to changes in download timeout requirements. Microsoft is working on a resolution, and IT administrators can use Known Issue Rollback (KIR) as a workaround by configuring the appropriate Group Policy for their Windows version. A device restart is required to apply these settings. Historical issues include a bug fixed in April 2025 affecting WSUS installations and another issue resolved in August 2025 related to the Windows 11 24H2 cumulative update. Additionally, a KIR fix was provided for a known issue causing the May 2026 Windows 11 security update to fail with error code 0x800f0922.

Microsoft confirms Windows 11 security update install issues

Microsoft has acknowledged a significant issue with the May 2026 Windows 11 security update, KB5089549, where users are encountering difficulties in installation, specifically the 0x800f0922 error code. This issue is primarily due to insufficient free space on the EFI System Partition (ESP), especially for devices with 10 MB or less available. The installation may fail during the reboot phase at around 35–36% completion, with users receiving notifications like "Something didn't go as planned. Undoing changes." Log entries may indicate insufficient ESP free space, such as "SpaceCheck: Insufficient free space" and "ServicingBootFiles failed. Error = 0x70." Microsoft recommends affected users utilize the Known Issue Rollback feature to reverse problematic updates and advises IT departments to install and configure the relevant Group Policy to address the issue.

Microsoft Changes ‘Most Windows Devices’ In June—Update Yours Now

Microsoft has alerted users that Secure Boot certificates will begin to expire in June, affecting most Windows devices. Users must update these certificates to avoid disruptions, as failing to install the latest Windows update could prevent devices from booting securely. A "one-time restart" will be required after the update to load new certificates. If the update is not installed by June 1, users may see a red stop icon in the Windows Security app. The update issued on May 12 was modified on May 15 to warn that it might fail to install. Microsoft indicates that most users will need to restart their PCs, although this may revert the update. The latest updates will expand the number of devices eligible for new Secure Boot certificates, but users are uncertain about how many PCs will be affected due to a phased rollout approach.

‘Avoid Disruption’—Microsoft Updates Windows Before June Deadline

Microsoft has released a security update for Windows 10 users, identified as KB5087544, which includes dynamic status reporting for Secure Boot states. Secure Boot certificates, in place for 15 years, are set to expire next month, and Microsoft advises users to update their certificates to avoid security risks. All Windows 10 PCs will require new certificates, but only those in the Extended Security Updates (ESU) program will be eligible for the update. Most Windows 11 devices will also need new certificates, except those purchased in the last two years. Failure to install the new certificates may affect device boot security. The update also addresses a security warning related to Remote Desktop Connection and may prompt some users to enter a BitLocker recovery key after restarting. New certificates will only be issued to devices that show successful update signals, and users should upgrade their Windows Security App to address potential issues. Notifications will be sent once new Secure Boot certificates are installed.

A known issue may require users to input their BitLocker recovery key after installation, affecting systems with specific BitLocker Group Policy configurations. Microsoft suggests removing the affected Group Policy setting and suspending and resuming BitLocker as a temporary solution.

Android Apps on Windows 11: Safe Alternatives After WSA

In 2025, Microsoft announced it would discontinue support for the Windows Subsystem for Android (WSA), making Android applications non-functional on Windows 11. This decision surprised many users in Indonesia who relied on these applications. HP developed a guide outlining secure alternatives to WSA, which included reputable Android emulators like BlueStacks, LDPlayer, and NoxPlayer, as well as native Windows alternatives such as Microsoft Teams and Microsoft 365 apps. Users were advised against unverified APK sideloading, unofficial emulators, and modified apps due to security risks. Microsoft’s end of support means no further security updates or bug fixes will be provided, and integration with the Amazon Appstore will cease. Users can continue using WSA apps, but they will be exposed to potential security threats. To migrate data from WSA, users were instructed to inventory apps, research alternatives, and export app data before performing a clean uninstall. Best practices for running Android apps safely on Windows included downloading from official sources and keeping software updated.

‘One Time Restart’—Microsoft Changes Windows After 15 Years

Microsoft is implementing changes to Secure Boot certificates for Windows PCs, marking the first expiration since 2011. New certificates must be installed on all devices before a deadline in June. Users can check their status via the Windows Security App. The new certificates will be distributed through regular monthly security updates, with some users already receiving them in April and others expected to see changes in May. Following these updates, users may experience additional restarts on their PCs. The update applies only to PCs eligible for security updates, meaning many Windows 10 PCs will not receive the new certificates, potentially exposing them to risks. Affected users are advised to enroll in Microsoft’s Extended Security Update (ESU) program.
