A rollback has been reported to fix this issue for those affected.
Windows 11 users with the latest feature/bug fix updates are complaining regarding storage performance.
The effect seems to be quite serious, with some saying that transfer performance has been halved, and others saying that it takes longer to load the OS and games.
Thankfully, according to victims of this bug, rolling back the update will restore their previous storage performance.
Additionally, in a quick test using the same updates as Windows 11, we were unable to reproduce this performance issue.
Windows 11’s Moment 2 Update arrived last week as a Patch Tuesday release, two weeks following it was featured on the Windows Experience blog.
Microsoft engineers have set up a Reddit thread to monitor and respond to feedback, but this thread doesn’t look like a happy place as many issues have been raised repeatedly.
Perhaps the most annoying bugs discussed in the comments relate to storage performance.
In the early stages of the complaint and feedback loop, we can’t be sure regarding the configurations affected, the scale of this issue, or what exactly is going on.
However, this issue seems to most affect users of NVMe SSD storage.
Another user, MrBigDog99, was lucid enough to save before-and-following screenshots from the CrystalDiskMark storage benchmarking tool.
Here we can see that disk writes are the most severely affected, but we also see that reads are not doing well.
Above is a screenshot MrBigDog99 observed and shared on Reddit showing the severe impact on storage performance.
As you can see, our systems using the same spec NVMe SSD were not affected by the Moment 2 Update (KB5023706).
Interestingly, Microsoft says it fixed slow file copying with the KB5023706 (opens in new tab) update, but the update backfires on these Reddit users.
Sadly, it seems that sometimes software makers fix one problem and cause another.
Windows 11 has been particularly unlucky when it comes to storage performance and related issues.
If your Windows 11 installation was slowed down by the latest update and you can’t (maybe) wait for Microsoft’s next patch to fix it, you can quickly roll it back with the steps below.
- Right-click the Start button and open Settings
- Near the bottom left, click the item Windows Update.
- Click Update History.[履歴の更新］をクリックします。
- Scroll down to the “Uninstall Updates” item and click it.
- Select KB5023706 and confirm the operation with the “Uninstall” button.
Last month, I wrote a guide on how to optimize SSD performance in Windows 10 or 11 for those who want to keep their systems in top shape.
We also recently shared with our readers how to disable VBS to speed up Windows 10 or 11 by up to 15%.

Commentary:
Sad news for all NVMe users
It has been reported that the SSD slows down following installing the KB5023706 update delivered by Windows Update on March 14, 2023.
It seems that it was fixed immediately, but the symptom does not seem to have improved at all.
Perhaps the cause has not yet been determined.
This kind of problem bothers me the most.
As of now, there seems to be no workaround other than uninstalling KB5023706.
It looks like I’ll just have to wait patiently until it’s fixed.
When I checked this KB5023706,
- Implement phase 3 of Distributed Component Object Model (DCOM) hardening.
- Addresses issues affecting computer accounts and Active Directory.
Sounds like an ActiveDirectory related security update.
is what they said.
It makes me cry that it’s an update that doesn’t seem to have much to do with general users.
