Microsoft is officially revealing it's working on x64 app emulation support for Windows on ARM today. From a report: Currently, Windows on ARM devices like the Surface Pro X can only run native 32- and 64-bit ARM apps, alongside 32-bit x86 apps. The vast majority of desktop apps, including Adobe's Creative Suite, have moved to 64-bit x86 and many have stopped supporting their 32-bit variants. This has left devices like the Surface Pro X unable to access certain apps, but Microsoft's new emulation support will mean any and all Windows apps will now work on Windows on ARM. The new x64 emulation support will start rolling out to Windows Insider testers in November and should arrive in a broader operating system update next year.

This new parameter allows a physical disk to be attached and mounted inside WSL 2, which enables you to access filesystems that aren't natively supported by Windows (such as ext4).

An anonymous reader shares a report: Windows 10 May 2020 Update, otherwise known as version 2004, was released in May with at least ten known issues. Microsoft later expanded the list of the problems and acknowledged that this feature update is also plagued with a bug that breaks Drive Optimize tool. After upgrading to Windows 10 version 2004, users observed that Optimize Drives (also known as defragmentation tool) is not correctly recording the last time a drive has been optimized. As a result, when you open the tool, you will see that your SSD drive says it 'Needs Optimization' even though you've manually optimized the drives already or automatic maintenance was run this morning. Since the last optimizations times are forgotten, Windows 10's built-in maintenance tool started defragging an SSD drive much more often when you restart Windows. With Windows 10 Build 19042.487 (20H2) for Insiders, Microsoft has finally resolved all problems with the Optimize Drives (also known as defragmentation tool).

An anonymous reader quotes a report from PC Gamer: A recent update to Windows 10 took away the ability for consumers to permanently disable Defender, the built-in antivirus software, no matter what the reason. However, Defender should voluntarily step aside if it detects the installation of a third-party AV program (emphasis on should). Before the update, if a user wanted to disable Defender on a permanent basis, they could edit a registry key called DisableAntiSpyware. That is no longer the case. "DisableAntiSpyware is intended to be used by OEMs and IT Pros to disable Microsoft Defender Antivirus and deploy another antivirus product during deployment. This is a legacy setting that is no longer necessary as Microsoft Defender antivirus automatically turns itself off when it detects another antivirus program. This setting is not intended for consumer devices, and we've decided to remove this registry key," Microsoft explains in a support document.
