To address slowdowns and glitches in Windows 11, users should verify several settings before considering a complete reinstallation. Key actions include: 1. Check for Windows Updates: Navigate to Settings > Windows Update to install patches and update device drivers. Uninstall problematic updates if necessary. 2. Manage Startup Applications: Use Task Manager (Ctrl+Shift+Esc) or Settings > Apps > Startup to disable unnecessary auto-starting applications to improve boot speed. 3. Pause OneDrive Syncing: Temporarily pause OneDrive syncing during resource-intensive tasks to prevent performance degradation. 4. Adjust Visual Effects: Disable Transparency effects and Animation effects in Settings > Personalization > Colors and Settings > Accessibility > Visual effects, respectively, to reduce GPU strain. 5. Limit Notifications: Turn off notifications in Settings > System > Notifications to minimize interruptions. 6. Restrict Background Activity: Set background app permissions to "Never" for infrequently used applications to conserve memory and disk usage. 7. Run Security Scans: Use Windows Security to perform a Quick scan and ensure that real-time protection features are enabled to detect malware and adware. 8. Browser Maintenance: Reset browser settings, remove unknown extensions, and enable tracking protection to improve resource management. If issues persist, further steps include running System File Checker, testing memory, checking storage health, or performing a repair install of Windows.

A new native NVMe storage driver has been introduced in Windows Server 2025, aimed at improving SSD performance by reducing CPU overhead and enhancing IOPS performance. Users have found a way to enable this driver on Windows 11 through manual registry edits, although Microsoft has not officially supported this for consumer versions. The driver implementation in Server 2025 could lead to an 80% increase in IOPS and a 45% reduction in CPU usage, but these figures are specific to server workloads. Community testing on Windows 11 version 25H2 has shown performance improvements of 10-15%. Enabling the driver requires editing the registry, and users must back up the registry or create a restore point beforehand. After activation, NVMe drives will appear under "Storage Media" in Device Manager. Some users may experience compatibility issues with SSD management utilities post-activation. To revert to the default NVMe driver, users can delete the added DWORD entries from the registry and restart the system. This adjustment is experimental and may not guarantee performance upgrades.

Recent discoveries have revealed a registry tweak that can enhance the performance of NVMe SSDs on Windows 11, particularly improving random 4K speeds. Traditionally, Windows has treated most drives as SCSI, limiting the potential of NVMe drives. Microsoft is introducing native NVMe support in Windows Server 2025, which bypasses the SCSI conversion process for improved speed and efficiency. Users can achieve similar enhancements on Windows 11 through specific registry modifications, which must be done at their own risk. The necessary driver is included in recent updates for both Windows Server 2025 and Windows 11. Users need to adjust three registry values to enable this functionality. Once modified, NVMe drives will appear under 'Storage Media' in Device Manager. Reports indicate significant performance gains, with one user noting increases of 45% in random 4K read and 49% in write performance. Microsoft suggests enterprise users could see up to 80% higher IOPS and a 45% reduction in CPU cycles. The WD Black SN8100 SSD is noted for its high random 4K speeds, loading games faster than competitors. Many users have pointed out that Linux has had native NVMe support for some time.

Windows users have relied on the disk.sys driver for storage management since 2006, which has not changed significantly despite support for NVMe since Windows 8.1. Microsoft has introduced nvmedisk.sys for Windows Server 2025 and a version in Windows 11 25H2, which improves performance by enhancing integration with NVMe technology. Tests show that nvmedisk.sys offers better raw throughput in sequential and random read/write tasks compared to disk.sys, as it removes the legacy SCSI translation layer, reducing overhead and improving latency, particularly on high-end SSDs. However, enabling nvmedisk.sys may cause system instability or boot failures if the SSD controller lacks compatibility, and users are advised to check the current driver in Device Manager and back up data before switching drivers. The new driver is still in a soft launch phase, and there is uncertainty about when it will be available in a stable build.

Windows has supported the NVMe storage media protocol since Windows 8.1, but the default driver, disk.sys, may not provide optimal performance. Microsoft has introduced a new driver, nvmedisk.sys, with Windows 11 25H2 and Windows 2025, aimed at improving NVMe performance. Users can check if they are using the older driver via Device Manager. The new driver has the potential to enhance performance for compatible NVMe drives in both sequential and random workloads. However, compatibility issues exist, as not all NVMe SSDs support nvmedisk.sys, which could lead to boot problems with Windows 11. Notebookcheck has published a guide on enabling nvmedisk.sys, which involves modifying three Windows Registry values, and it is advised that users back up their data before making changes.

The process of enhancing SSD performance involves modifying the Windows registry with specific commands to unlock improvements in data transfer speeds, particularly for PCIe 4.0 SSDs. The commands to add values to the registry are: 1. reg add HKEYLOCALMACHINESYSTEMCurrentControlSetPoliciesMicrosoftFeatureManagementOverrides /v 735209102 /t REG_DWORD /d 1 /f 2. reg add HKEYLOCALMACHINESYSTEMCurrentControlSetPoliciesMicrosoftFeatureManagementOverrides /v 1853569164 /t REG_DWORD /d 1 /f 3. reg add HKEYLOCALMACHINESYSTEMCurrentControlSetPoliciesMicrosoftFeatureManagementOverrides /v 156965516 /t REG_DWORD /d 1 /f After executing these commands, a system restart is required to see changes in the Device Manager, where SSD drives will shift from "Disk drives" to "Storage disks," indicating the use of the nvmedisk.sys driver. Users may experience a 10 to 15% increase in data speeds for PCIe 4.0 SSDs, with even PCIe Gen 3.0 SSDs showing improvements. Benchmark results indicated up to a 45% increase in sequential reading performance and a 15% increase in write performance. For a specific 1TB SSD, sequential read performance improved by approximately 23%, and write performance increased by 30%. However, caution is advised as some users reported issues with SSD management tools, and compatibility with all NVMe SSDs is not guaranteed.

Windows 11 users are facing installation issues with the KB5068861 update from the November 2025 Patch Tuesday release, which addresses 63 critical security vulnerabilities. Errors reported include 0x80070306, 0x800f0983, and 0x800f081f. Affected users can wait for an optional release or use the Media Creation Tool, which downloads the same patch. Some users have reported a malfunctioning SMB search feature after the update. The installation errors have prompted reports of specific error codes, and attempts to resolve them through SFC scans or health checks have been largely ineffective. Downloading the .msu package from the Microsoft Update Catalog is recommended, followed by an installation attempt. If unsuccessful, the Media Creation Tool can be used while retaining user data. The November 2025 Update includes enhancements like a revamped Start menu, improved battery icons, and performance improvements, particularly for gamers. However, some users have encountered Bluetooth connectivity issues, especially on AMD PCs, with a temporary fix involving adjustments in Device Manager. The KB5068861 update has also caused a bug affecting search functionality over shared networks, leading to slower search results or empty listings for businesses. This issue arises from a breakdown in communication between the Windows client and the server’s search index. Users can restore functionality by restarting the Windows Search service or rebuilding the index. Additionally, the remote search functionality over SMB is compromised, preventing the Windows client from utilizing the server’s index. Users may need to uninstall the update to restore functionality, which requires disabling the Sandbox feature first. Specific DISM commands can be used to identify and remove the update, or it can be uninstalled through the Settings menu.
