Tested: Windows 11 has fully removed the legacy tool abused by cybercriminals for malware and ransomware, called WMIC

Windows 11 will remove the Windows Management Instrumentation Command-line (WMIC) tool in the upcoming September 2026 Update, marking its complete elimination after being deprecated in earlier versions. Testing of early builds shows that WMIC is no longer accessible, with attempts to use it resulting in a "command not recognized" error. Previously, WMIC was available as an optional feature, but it will no longer be included or reactivatable in the new update. Microsoft stated that this removal aims to improve the security and reliability of Windows, as WMIC has been exploited by cybercriminals for attacks. The September 2026 Update will also introduce other enhancements, including the ability to disable Bing in Windows Search and improvements in app speed.

Windows 11’s latest Patch Tuesday update is breaking games and turning off PCs — This temporary fix might get ARC Raiders and The Finals running again

A bug introduced in the Windows 11 update (KB5121003) has caused crashes for some users, specifically affecting installations of Windows 11 versions 25H2 and 24H2 with OS builds 26200.9168 and 26100.9168. Embark Studios has acknowledged the issue, linking it to a change in the inpoutx64.sys file, and is working on a fix while providing a temporary workaround. The workaround involves stopping and deleting the inpoutx64 driver and removing the corresponding file from the system. Users can also choose to roll back to a previous version of Windows 11 until an official fix is released.

Windows 11 KB5121003 update breaks Teams and Outlook on ARM devices

Following the KB5121003 Patch Tuesday update, users on ARM64 devices like Surface Laptop 7 and Surface Pro 11 are facing startup failures with Microsoft Teams and New Outlook, while traditional Win32 applications remain unaffected. Reverting to the previous update restores functionality, but recovery options have not resolved the issue. The root cause appears to be broken AppModel Runtime package states, leading to dependency issues and 0x80073CFC errors. This problem is similar to one caused by update KB5094126 earlier this year. Creating new Windows profiles offers only temporary relief, and administrators are advised to pause the deployment of KB5121003 on ARM devices until the issue is addressed.

Windows 11 is fully removing a legacy tool that malware and ransomware have abused for years, meet WMIC

Microsoft is removing the Windows Management Instrumentation Command-line (WMIC) from Windows 11 to enhance security by eliminating a tool that has been exploited by malware and ransomware. WMIC will not be included in Windows 11 versions 24H2, 25H2, and 26H2, with complete removal scheduled for the August 2026 Patch Tuesday update. The decision to remove WMIC is based on the availability of more secure alternatives like PowerShell. WMIC has been a vector for attacks, allowing threat actors to disable antivirus solutions and access sensitive data. Microsoft has phased out WMIC since 2021, encouraging users to transition to modern tools while continuing to support the underlying Windows Management Instrumentation (WMI) infrastructure.

Don’t panic if Windows 11 reboots multiple times for security updates, here’s why it’s happening

Windows PCs are experiencing multiple reboots during the installation of monthly cumulative updates, particularly due to updates related to Secure Boot certificates and accompanying firmware updates. Microsoft is rolling out the Secure Boot certificate update to millions of Windows 11 and Windows 10 devices, with users who haven't received the certificates expected to do so soon, unless firmware limitations arise. Microsoft has acknowledged that multiple reboots may occur during this rollout. The August 2026 Patch Tuesday update addressed around 400 security vulnerabilities and included a Secure Boot certificate update for a wider range of devices. It is advised not to delay updates beyond three days to avoid potential AI-driven security threats. The August 2026 Update also activates the Low Latency Profile for app launches and improves file size displays in File Explorer. Reports indicate that devices lacking the Secure Boot 2023 certificate have successfully received it following this update, and Microsoft will continue deploying certificates via Windows updates in the coming months.

‘This one just needs a script’: Researchers find ultimate Windows kill switch which can disable antivirus w…

Researchers from the University of Birmingham and Durham University discovered a vulnerability in consumer DDR4 and DDR5 memory chips, termed "Download more RAM," which allows attackers to misreport memory configuration, potentially doubling the perceived RAM. This manipulation enables unauthorized access to memory allocations, bypassing Windows' Virtualization-based Security (VBS) and Hypervisor-Enforced Code Integrity (HVCI), and disabling antivirus software. The vulnerability affects major manufacturers like Corsair, G.Skill, and ADATA, which collectively hold over 55% of the high-performance memory market. Microsoft has patched the vulnerability, cataloged as CVE-2026-23670, with a medium severity score of 5.7/10, in the April 2026 Patch Tuesday update. Corsair has introduced a feature to enable write protection on their memory modules, and other tools are available for additional protection.

Windows 11 Expands Low Latency Profile CPU Boost to All Apps in August Patch Tuesday Update

Microsoft has expanded its Low Latency Profile (LLP) feature to all Windows 11 applications through the KB5121003 update, which is part of this month's Patch Tuesday. This update temporarily boosts CPU frequency to speed up app launches and is now available for most applications and Win32 programs. Following the installation of the update, standard applications like Notepad, Calculator, and web browsers such as Chrome showed faster opening times. The LLP feature is being rolled out gradually via Microsoft's Controlled Feature Rollout system, and users can enable it early using the ViveTool program if it does not appear immediately. Critics have described LLP as a superficial enhancement, while Microsoft has defended it by comparing it to similar strategies used by Apple in macOS.
