We finally know how Windows XP’s infamous FCKGW product key ended up everywhere

Windows XP was released in two versions: Retail for individual consumers and Volume for Microsoft's partners and OEMs. The product key FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 became widely recognized due to a potential leak by an insider at a major OEM, which was then spread by the pirate group Devils0wn. The Volume version's activation system required a unique key, but the FCKGW key was incompatible with the standard installation CD. To verify the legitimacy of Volume discs, the activation system searched for a secret 10MB binary blob exclusive to the Volume media. Microsoft blacklisted the FCKGW key with Service Pack 1 and implemented further security measures with Service Pack 2, restricting access to certain updates. Contrary to prior beliefs, the key's functionality was not due to a simple key generation algorithm but was designed by skilled engineers.

Not sure whether to use Windows Hello or Enhanced Sign‑in Security? This breakdown makes the choice easy

Microsoft will introduce Enhanced Sign-in Security (ESS) in the August 2026 update for Windows 11, allowing support for compatible external fingerprint readers. ESS aims to enhance the security of the authentication process rather than improve the accuracy of biometric recognition. Unlike standard Windows Hello, which processes biometric authentication through the operating system, ESS utilizes Virtualization-Based Security (VBS) and Trusted Platform Module (TPM) 2.0 to isolate sensitive operations in a protected environment. ESS-compatible fingerprint readers have dedicated secure processors, store templates internally, and communicate with the operating system via encrypted channels. Users can enable ESS by navigating to Settings > Accounts > Sign-in options on their devices. If a device does not support ESS, standard Windows Hello remains a robust authentication option.

Windows Hello vs. Enhanced Sign‑in Security: Which sign‑in method actually keeps your Windows 11 PC safer, and what’s the difference?

Microsoft will introduce Enhanced Sign-in Security (ESS) in the August 2026 update for Windows 11, which will support compatible external fingerprint readers. ESS aims to strengthen the authentication process against potential attacks by shifting processing to isolated, hardware-protected environments using Virtualization-Based Security (VBS) and TPM 2.0 technology. Unlike standard Windows Hello, which processes biometric authentication through the operating system, ESS-compatible devices perform more processing within the hardware itself, ensuring that only authentication results are sent to the OS. To enable ESS, users must navigate to Settings > Accounts > Sign-in options and follow prompts to set up their fingerprint recognition. Existing non-ESS biometric enrollments will be removed during the upgrade to ensure security.

Microsoft Edge won’t let you access its password manager without Windows Hello

Microsoft Edge has removed the use of master passwords for its password manager on Windows, transitioning to Windows Hello for authentication in version 145 of the browser. This update prioritizes security by allowing access through biometric options or a PIN, rather than traditional passwords. The rollout of this update began on June 4, 2026.

Minecraft Servers Are Down and Players Have Been Locked Out for Hours

On June 3, 2026, Minecraft players were locked out of both Bedrock and Java editions due to significant disruptions in authentication and multiplayer services, marking the second major outage in less than a week. The issues began around 12 am PDT, affecting the Realms multiplayer system and resulting in error messages for players. A previous outage on June 1 was attributed to a failure in Microsoft Azure, impacting both Minecraft and Xbox Live. On June 3, over 800 problem reports were logged, indicating a systemic failure. The error message faced by Bedrock players suggested problems with Microsoft’s central authentication system. The cause of the June 3 outage remains unconfirmed, and Mojang has not provided any updates. Players are advised to monitor official channels for updates, with single-player mode available for Java players while Bedrock players face authentication failures.

Microsoft Changes Windows Security After 15 Years—Update By ‘End Of April’

Microsoft is updating the Secure Boot certificates for Windows PCs, which have been in place since 2011. This update will begin with the April security patch rollout and is expected to be fully deployed across PCs by the end of April 2026. Users can check the status of the Secure Boot update by navigating to Windows Security > Device security > Secure Boot, where a color-coded badge will indicate the current status. The update will install new certificates and confirm if user action is necessary. If the badge is red, immediate attention is required. Microsoft is enhancing the visibility of the Secure Boot certificate status within Windows Security to aid users in verifying the update. The certificates will not expire for several more weeks, so users should check their systems by the end of the month.
