The process stinks. The gradual rollouts make it really hard to get excited about the fixes and enhancements because you literally don't know what you're gonna get and when you're gonna get it. The lack of consistency and transparency on timing is frustrating as hell.

I read that MS were getting rid of A/B testing and activating features straight away

Makes sense - why on earth have A/B testing - just makes things more complicated than they need to be. Simply roll out a new build - it either works, doesn't work or partially works - deal with those issues.

Please also above anything else BEFORE releasing a new build TEST REGRESSION (Caps intended) - although using cheap off shored places for "development" -- ha ha that's a laugh since most people using those centres usually have to send the entire development process out to those places first it's highly unlikely they would now what regression was - far less on how to test it - and it's a complicated - certainly a non trivial process.

Microsoft is ending gradual feature rollouts (also known as Controlled Feature Rollouts or A/B testing) in the Beta channel, not the Release Preview channel.

You can use this Enable 2026-08 Security Update (KB5121003) (26200.9168) Features (Override 14).reg registry entry to still enable certain features in build 26200.9267.

Most of the features have existed since the earlier security updates.

Thanks @uncyler825 that worked great!

Is there nothing new feature id wise to add in this build then?

MS deleted the number of result from each type of result (In the right screenshot).
Feature that was in build 26200.7922 :

[Search on Taskbar]

New! Group headers now show the number of results, so you can quickly see when more results are available. Select a group header to see all results for that group and hide results from other groups.

Improving File Explorer & Context Menu: faster, simpler, and more customizable

Hi Windows Insiders, File Explorer is one of the most used experiences on Windows. It's where you get work done: organizing files, finding what you need, and moving content seamlessly across local storage and the cloud. Earlier this year, we

blogs.windows.com

The Customize menu also works on retail builds 26100.9267 (24H2) and 26200.9267 (25H2), and newer builds.

You can enable it with:

ViVeTool /enable /id:60813048,49453572

Or just copy the text below into Notepad, save it as a .reg file, and import it.

Code:

Windows Registry Editor Version 5.00


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\14\156965516]
"EnabledState"=dword:00000002
"EnabledStateOptions"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\14\4055089295]
"EnabledState"=dword:00000002
"EnabledStateOptions"=dword:00000000

I enabled that earlier today on two beta machines. Worked on one but didn't appear on the second so I might have to try the reg keys you posted.

Why does Send To , have an option desktop.ini? This is when using the new Context Menu options

Does this update fix the issue where icons disappear from the taskbar after waking from sleep?
This problem has been going on for a few months now, haha.
