Windows 11 has had a number of issues since it launched in October. One of the most frustrating was how Microsoft’s latest operating impacted the performance of some types of NVMe solid-state drives. If you’ve upgraded to Windows 11 and have seen reduced performance, you aren’t alone.
Microsoft promised to release a patch to remedy the issue, and now it has made good on that claim with Patch KB5007262, released on November 22 via the Windows Insider program. Once downloaded and installed, it should boost your device’s performance. However, you’ll need to manually install the update since it isn’t going out as part of an automatic Windows update.
What’s interesting about this particular problem is how greatly it affected SSD write speeds. A post in Microsoft’s forums from October showed benchmarks performed in CrystalDiskMark. Results showed a reduction in random write speeds that approached 50 percent when comparing Windows 11 and Windows 10 (via Beta News). Redditors and other users on Microsoft's forums also posted similar complaints about Windows 11 reducing SSD performance speeds.
If you’re interested to see what else was fixed in the KB5007262 update, you can read the full release notes on Microsoft’s website. If Windows 11 is still running slow for you, be sure to check out our guide on how to speed up Windows 11.
