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.

Retired Microsoft Engineer details the story about the famous leaked FCKGW Windows XP key — copy protection used 10MB of encrypted Microsoft Bob for validation

The most recognized Windows XP product key is FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8. Windows XP was released in two formats: Retail for consumers and Volume for Microsoft partners and OEMs. The Volume discs were not intended for the general public and were designed for mass installations without individual activation. The final CD version, Release to Manufacturing (RTM), was completed on August 24, 2001, two months before the official launch on October 25. A leak of the Volume image and its Volume License Key (VLK) is believed to have originated from a major OEM, possibly Dell or Intel, which was exploited by the pirate group Devils0wn, allowing broader access to Windows XP.

Ex-MS engineer reveals the story behind the infamous ‘FCKGW’ Windows XP key: ‘Pirates started baking the key into images or just writing it on the CD with a Sharpie’

David Plummer, a former Microsoft engineer, was the primary author of Windows XP's Product Activation system, which included the infamous product key FCKGW. This key became widely used on pirated copies of the operating system. Plummer created the activation system by compressing and encrypting disc data, ensuring its security. The FCKGW key was specifically tied to certain data configurations, making it ineffective on standard XP CDs. A piracy group, Devils0wn, leaked a complete Windows XP Pro Corporate ISO and the valid FCKGW key just five weeks before the official launch, allowing unauthorized installations. Microsoft responded by blacklisting product IDs associated with the compromised keys in Service Pack 1 and blocking updates for installations using the FCKGW key in Service Pack 2. Valid, un-leaked Volume License Keys (VLKs) remained functional for years after the incident. Plummer noted that the media and the key were leaked before the product reached stores, preventing the intended hardware-binding from functioning.

Microsoft reveals why 32-bit Windows was limited to 4GB RAM, and it wasn’t a technical limit

32-bit Windows is commonly thought to be limited to 4GB of RAM due to its 32-bit address space, but this overlooks the role of Physical Address Extension (PAE), which allows access to more than 4GB of RAM on compatible processors. PAE enables 32-bit x86 processors to use 36-bit physical addresses. Windows allocates a 4GB virtual address space to each 32-bit application, with 2GB reserved for the application and 2GB for system use. Windows Server 2003 SP1 Enterprise can support up to 64GB of RAM, while the Datacenter edition can handle 128GB. Microsoft did not extend this capability to consumer editions due to the complexities and potential issues with hardware drivers, which often assume a 32-bit framework. Modifying drivers for PAE can be challenging, as incorrect assumptions about physical and virtual addresses can lead to memory corruption. To mitigate risks, Microsoft capped physical address space at 4GB in Windows XP SP2 and Windows Server 2003 SP1 Standard Edition. Server environments typically have more controlled hardware selections, allowing for the use of drivers that are tested for compatibility with addresses exceeding 4GB. Microsoft began discouraging the production of 32-bit systems in 2020 and ended 32-bit edition production with Windows 11.

I gave Windows 11 an old-school makeover by restoring its classic icons

Users can customize icons in Windows 11 by following different methods depending on the type of icon. For folders and shortcuts, right-clicking the item and selecting Properties allows users to change icons easily. Taskbar items require pressing Shift while right-clicking the closed app. Desktop icons like "This PC" and the Recycle Bin can be modified through Settings > Personalization > Themes > Desktop icon settings. More complex changes, such as altering icons for file types or drives, involve editing the Windows registry. Windows retains a selection of classic icons within DLL files, including moricons.dll, pifmgr.dll, and netshell.dll. Users can also access the Windows Icon Archive project for a repository of icons from various Windows versions, though .png files need conversion to .ico format for use. Limitations include the inability to change icons for new folders automatically, modifications not reflecting in Quick Access for special folders, and restrictions on altering application icons. Programs like OpenShell can help modify taskbar and Start menu icons, but achieving a perfect replica of older versions is not possible.

ReactOS 0.4.16 serves ’90s Windows nostalgia with fewer bugs

ReactOS has released version 0.4.16, which includes a unified boot and live CD image, a graphical installer, and significant upgrades to video, audio, networking, and storage stacks. The update addresses compatibility issues with legacy software, particularly with video drivers and the kernel’s system page table entries, improving stability. A new HD audio bus driver has replaced an older implementation, and the UniATA driver has been replaced with a new ATA driver for better compatibility and boot times. Networking capabilities have improved with expanded support for adapters and asynchronous connections. A headless Server Core installation type has been introduced, and compatibility restrictions with Windows Server 2003 have been lifted. ReactOS remains in an alpha state, and version 0.4.16 is available for download.

Whatever happened to Minesweeper and 3D Pinball on Windows?

Microsoft included the Solitaire Collection with Windows 10 and Windows 11, while many classic games required separate downloads. The company has shifted focus towards its Xbox platform, leading to the discontinuation of games like 3D Pinball: Space Cadet due to technical challenges. Raymond Chen noted that the transition from 32-bit to 64-bit architecture caused significant issues for 3D Pinball, including a bug where the ball would pass through objects. Ultimately, the decision was made to exclude Pinball from the product lineup to avoid the complexities of porting its code.

Why Windows stopped including fun games like Minesweeper, Solitaire, and Pinball

Microsoft integrated games into the Windows operating system from its early versions, starting with Reversi in Windows 1.0 in 1985 and introducing Solitaire in Windows 3.0 in 1990. Over the years, various versions of Windows included a range of built-in games, peaking with Windows Vista and Windows 7, which featured titles like Chess Titans and Mahjong Titans. However, with the release of Windows 8, Microsoft removed classic games from the operating system and transitioned to an app-centric model, directing users to the Windows Store for gaming. The Microsoft Solitaire Collection became a single app, while other games were made available as separate downloads. This shift marked a change in how Microsoft approached gaming, moving from integrating games as part of the OS to treating Windows as a platform for independent applications and services.

“God Mode? Hardly.” Microsoft debunks Windows 11’s God Mode, but the trick still works

The "God Mode" in Windows is activated by creating a folder and renaming it to GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}, which transforms the folder icon to resemble the Control Panel and displays a comprehensive list of all settings tasks available in Windows. This trick was clarified by Microsoft engineer Brandon Paddock, who stated that the name "GodMode" is misleading, as the folder can be named anything with the same CLSID code, and it merely exposes two documented elements of the Windows shell. The functionality was intended for developers and not casual users, and the trick could be altered or removed in future updates.
