How To Use the Windows Malicious Software Removal Tool

The Windows Malicious Software Removal Tool (MSRT) identifies and eliminates specific high-risk malware families on Windows devices. It is updated monthly by Microsoft and is integrated into all supported versions of Windows 10 and Windows 11. MSRT functions as a cleanup utility, scanning for known active malware infections. Users can run the tool manually by pressing Windows + R, typing mrt, and selecting a scan type. MSRT is recommended for use after installing software from unfamiliar sources, when a PC shows unusual behavior, for quick secondary scans, or in response to Windows Defender alerts. Manual downloads of MSRT are available for offline systems. The tool maintains a detailed log of scans in the Debug folder. MSRT targets malware such as MyDoom, Blaster, and Sasser, and while it removes infections, it does not provide real-time monitoring. Microsoft updates the tool monthly, and it runs automatically after updates but can also be launched manually.

Windows Dev Drives are the speed upgrade you’re not using

Dev Drives are virtual drives introduced in the Windows 11 version 22H2 update, designed specifically for software development. They can be created as partitions on physical drives or as virtual hard drives (VHDs) and use the ReFS file system instead of NTFS. This allows them to bypass continuous malware checks by Microsoft Defender, resulting in performance improvements of up to 41%. Dev Drives are intended for developers engaged in data-intensive tasks, but storing non-development files on them poses security risks. They can enhance workflow efficiency for developers and are accessible through the Settings app in Windows 11.

Fake Windows Defender notifications are on the rise

Microsoft's latest AI language interpreter has raised concerns among cybersecurity experts, as it has inadvertently provided new opportunities for cybercriminals. Scammers are using fake Windows Defender pop-ups, which appear authentic, to deceive users into granting unauthorized remote access to their computers. Certain ransomware groups have found ways to disable Windows Defender remotely using trusted Windows drivers, leaving users vulnerable without alerts. These fraudulent notifications often lock users' browsers and prompt them to call a number associated with the scammers, who then guide them through granting access under false pretenses. The pop-ups originate from compromised websites, malicious ads, or bundled software, exploiting the familiar Defender name to instill fear. Relying solely on Windows Defender is risky, as it struggles against sophisticated attacks, lacks deeper monitoring, and is a prime target for cybercriminals. A multi-layered security approach, including reputable third-party security packages like Trend Micro’s Internet Security, is recommended. Additionally, maintaining smart security habits, such as keeping systems updated and using strong passwords, is essential for effective protection.

Data Doctors: Beware fake Windows Defender alerts

Microsoft's Windows Defender has vulnerabilities that can be exploited by cybercriminals, including a method to remotely disable it using a trusted Windows driver. There has been an increase in counterfeit "Windows Defender" pop-ups that prompt users to call a phone number, connecting them to scammers. These pop-ups do not originate from Microsoft and are often triggered by compromised websites or malicious ads. Scammers use these alerts to gain remote access to victims' computers under the pretense of fixing non-existent issues, often charging for fraudulent services or installing malware. Windows Defender struggles against advanced threats, lacks deeper monitoring capabilities, and is a prime target for attackers due to its widespread use. A multi-faceted security approach, including third-party solutions like Trend Micro, is recommended to address these gaps and enhance protection. Additionally, maintaining smart security habits, such as updating software and using strong passwords, is crucial for overall system security.

As Windows turns 40, Microsoft faces an AI backlash

Microsoft is transforming Windows into an "agentic OS" by integrating advanced AI capabilities, as announced at the Ignite conference. The reception has been mixed, with users expressing concerns similar to those after the release of Windows 8. Windows chief Pavan Davuluri faced criticism on social media regarding the initiative, with users calling for a return to simpler interfaces like Windows 7. Despite acknowledging user pain points, many feel that the focus on AI features overshadows necessary improvements. The integration of AI tools like Copilot has received mixed reviews, with reports of unreliability. CEO Satya Nadella envisions a shift towards AI agents performing tasks, while also emphasizing the need for user control over their experience. Microsoft aims to balance innovation with user preferences, allowing users to opt-in to AI features at their own pace. Recent developments include a hotfix driver from Nvidia for Windows 11 performance issues, the return of a calendar feature to Windows 11, integration of Google's AI models into GitHub Copilot, and enhancements in security and performance for Windows and Office applications.

Still on Windows 11 23H2? Microsoft will soon force you to upgrade to 25H2 – for your own good

Microsoft has announced that support for Windows 11 version 23H2 will end on November 11, 2025, meaning that Home and Pro editions will no longer receive security updates.

Task Manager creator says Windows 11 has turned into a sales channel for all products

Dave Plummer, a retired Microsoft Windows engineer, shared a video discussing the dissatisfaction with Windows 11 among long-time users. He attributes this discontent to Microsoft's focus on integrating its own products into the user experience, which alienates loyal users. The shift began with Windows 10, which adopted a "Windows as a service" model and aimed to create a unified user base for monetization through cloud services. Windows 11 has further evolved into a platform that promotes Microsoft products over user experience, leading to intrusive advertising within the OS. Plummer suggests improvements, including a genuine "Pro Mode" for power users, a "privacy ledger" for telemetry transparency, and better options during setup. He emphasizes the need for Microsoft to refine the Windows experience to regain user trust.
