Hi Dennis,
I don't have it yet either.
Per the Blog it's a gradual rollout.
When will Smart App Control be on for everyone?

On Nov 7th it was announced that "Smart App Control" can now be turned on without having to do a clean install of windows. I'm still not seeing that option... Anyone able to do this yet?

Thanks for the fast reply. Now I know I'm not the only one that it hasn't come to yet.. :)
Would be nice if they rolled it out a little quicker though... lol

This is, now, a CFR with March 26, 2026—KB5079391 (Optional Update). It will, also, be with April Patch Tuesday.
From the KB5079391 blog...
[Smart App Control] New! You can turn Smart App Control (SAC) on or off without needing a clean install. To make changes, go to Settings > Windows Security > App & Browser Control > Smart App Control settings. When turned on, SAC helps block untrusted or potentially harmful apps. To learn more, see App & Browser Control in the Windows Security App. This feature was previously disclosed in January 2026 (KB5074105) and is now beginning to roll out.-

"⭐ The April 2026 Optional Update (KB5079391) does bring back the SAC toggle
Two independent, reputable sources confirm it:
✔ Pureinfotech
Says the April 2026 update “makes changes to Smart App Control to manage the feature without reinstallation.”
✔ Windows Latest
Says the optional update “adds the ability to turn Smart App Control (SAC) on or off without reinstalling the OS.”
This is exactly the feature Microsoft previously paused — and now it’s back.
🟦 So what changed?
Microsoft originally pulled the SAC toggle because:
telemetry wasn’t strong enough
too many false positives
enterprise complaints
baseline logic wasn’t ready
But now, with the April 2026 update:
⭐ They’ve re‑enabled the toggle
⭐ It’s shipping as an optional update
⭐ It will roll into Patch Tuesday on April 14
⭐ It will reach Stable Channel devices"
"🟦 Bottom Line
Dennis, the post you saw is correct:
⭐ Smart App Control’s new toggle is returning in the April 2026 optional update."
