Windows 11 February 2026 Update (KB5077181) — Cross-Device Resume, Smart App Control Toggle & Complete Changelog

Windows 11 February 2026 Update (KB5077181): Cross-Device Resume, Smart App Control & Everything New

Microsoft's February 2026 Patch Tuesday update for Windows 11 is here — KB5077181 (Build 26200.7840 for version 25H2 and 26100.7840 for version 24H2). While it doesn't have a flashy consumer feature name, this update packs several genuinely useful improvements, particularly Cross-Device Resume with Android phones and the ability to toggle Smart App Control on and off without reinstalling Windows.

For Indian users, the Cross-Device Resume feature is especially relevant — it works with Samsung, Xiaomi, OPPO, vivo, and HONOR phones, which collectively dominate over 80% of India's smartphone market. Let's go through everything new.

Cross-Device Resume: Seamless Phone-to-PC Workflow#

This is the headline feature. Cross-Device Resume lets you start an activity on your Android phone and continue it on your Windows 11 PC — or vice versa. It works through the Microsoft Copilot app installed on your phone.

How It Works#

1. You're browsing a website, reading an article, or working on a document on your phone
2. When you sit at your PC, Windows 11 shows a notification: "Continue on PC?"
3. Click the notification, and the activity opens on your PC exactly where you left off
4. Works the other way too — start on PC, continue on phone

Supported Phone Brands#

Cross-Device Resume works with Android phones from the following brands via the Microsoft Copilot app:

• Samsung — Galaxy S, A, M, and F series
• Xiaomi — Xiaomi, Redmi, and POCO sub-brands
• OPPO — OPPO and OnePlus devices
• vivo — vivo and iQOO devices
• HONOR — HONOR Magic, X, and 200 series

India context: These five brands account for over 80% of smartphones sold in India. Unlike Apple's ecosystem lock-in (iPhone + Mac only), Microsoft is making cross-device features work with the phones Indians actually use — a smart strategic move.

Supported Activities#

Cross-Device Resume now works with more apps than the initial preview, including:

• Microsoft Edge: Continue browsing tabs and reading articles
• Microsoft 365: Resume Word, Excel, PowerPoint documents
• OneNote: Continue note-taking across devices
• Outlook: Continue composing emails
• Third-party apps: Support is expanding — developers can integrate via the Cross-Device SDK

Setup Requirements#

• Windows 11 version 24H2 or 25H2 with KB5077181 installed
• Microsoft Copilot app installed on your Android phone
• Same Microsoft account signed in on both devices
• Bluetooth and Wi-Fi enabled on both devices
• Phone Link app configured on your PC (comes pre-installed with Windows 11)

Smart App Control: Finally, You Can Toggle It On and Off#

Smart App Control (SAC) is Windows 11's intelligent security feature that blocks potentially malicious or unwanted apps from running. Until now, once you turned SAC off, you couldn't turn it back on without reinstalling Windows — a frustrating limitation that prevented many users from experimenting with it.

What's Changed#

With KB5077181, you can now toggle Smart App Control on and off at any time from Windows Security settings. No Windows reinstall required.

How to Access#

1. Open Windows Security (search for it in Start menu)
2. Go to "App & browser control"
3. Click "Smart App Control settings"
4. Toggle between On, Evaluation mode, and Off

What Smart App Control Does#

• Blocks unsigned/untrusted apps: Prevents running applications that haven't been verified by Microsoft's cloud intelligence service
• Blocks potentially unwanted programs (PUPs): Adware, toolbars, and other junk software
• Evaluation mode: Monitors your app usage for a period, then decides whether SAC would be compatible with your workflow

Should You Turn It On?#

If you mostly use well-known apps (Chrome, Office, Adobe, etc.), SAC adds a meaningful security layer. If you frequently use niche software, developer tools, or apps downloaded from smaller websites, SAC may block them — in which case, keep it off or use Evaluation mode first.

Windows Hello: External Fingerprint Reader Support#

Enhanced Sign-in Security (ESS) for Windows Hello now supports external USB fingerprint readers. Previously, ESS only worked with built-in fingerprint sensors on laptops. This is a significant improvement for:

• Desktop PC users: Who don't have built-in biometrics and use external USB fingerprint readers
• Docking station setups: Laptop users who connect to external monitors and keyboards — the external fingerprint reader on the dock now works with ESS
• Enterprise environments: Where USB fingerprint readers are standard-issued security hardware

Accessibility Improvements#

Narrator Enhancements#

Windows Narrator — the built-in screen reader — receives significant updates:

• Granular control over spoken elements: Choose exactly what Narrator announces — headings, links, images, form controls — with individual toggles
• Customizable reading order: Define the order in which elements are spoken, tailored to your workflow
• Improved web navigation: Better handling of complex web pages and web applications

Voice Access Redesign#

Voice Access — which lets you control Windows entirely by voice — has a redesigned onboarding wizard:

• Language model selection: Choose and download speech recognition models for your language
• Microphone selection and testing: Built-in microphone setup and quality check
• Guided tutorial: Step-by-step walkthrough of basic voice commands

MIDI Improvements for Music Producers#

This update brings comprehensive MIDI 1.0 support improvements that music producers and audio professionals will appreciate:

• Full WinMM and WinRT MIDI 1.0 support with translation: Apps using either API framework can now communicate with MIDI devices seamlessly
• Shared ports: Multiple applications can access the same MIDI device simultaneously — no more fighting over MIDI port access
• Custom device names: Rename MIDI devices for easier identification in complex setups
• Loopback support: Route MIDI data between applications internally without external hardware
• App-to-app MIDI: Send MIDI data directly between applications — useful for complex DAW setups and live performance rigs

For India's growing music production community — especially bedroom producers using FL Studio, Ableton Live, and Reaper — these improvements eliminate common MIDI headaches that previously required third-party workarounds.

New Device Card in Settings#

The Settings home page now includes a new Device card that shows:

• Your device name and model
• Current Windows version and build number
• Quick links to device-specific settings
• Storage usage summary
• Battery health (for laptops)

A small but welcome quality-of-life improvement that puts frequently needed device information front and center.

Complete Feature Summary Table#

How to Install KB5077181#

1. Open Settings (Win + I)
2. Go to Windows Update
3. Click "Check for updates"
4. KB5077181 should appear — click "Download and install"
5. Restart your PC when prompted
6. After restart, verify: Settings → System → About → check build number is 26200.7840 (25H2) or 26100.7840 (24H2)

Note: This is a cumulative update — it includes all previous security patches. Installation typically takes 10–20 minutes depending on your hardware.

Known Issues#

As with most Windows updates, there are some known issues to be aware of:

• Cross-Device Resume may not work immediately: After installing, give it 24 hours for the feature to fully sync between devices. Ensure the Microsoft Copilot app on your phone is also updated
• Smart App Control evaluation data resets: If you toggle SAC back on, it may need to re-evaluate your app usage patterns from scratch
• Some MIDI devices may need re-pairing: After the update, some USB MIDI controllers may need to be unplugged and reconnected for the new MIDI stack to recognize them

Should You Update Immediately?#

Yes, for most users. This is a standard cumulative update with security patches, so delaying it leaves you exposed to known vulnerabilities. The new features are all additive — nothing changes about your existing workflow unless you actively enable Cross-Device Resume or toggle Smart App Control.

If you're a music producer using MIDI devices, test your setup after updating — the MIDI improvements should be beneficial, but complex setups may need minor reconfiguration.

The Bigger Picture: Microsoft's Cross-Platform Strategy#

Cross-Device Resume is part of Microsoft's broader strategy to make Windows the center of a cross-platform ecosystem — something Apple does with iPhone + Mac, but Microsoft is doing with any Android phone + Windows. In India, where Android has 95%+ market share and Windows dominates PC usage, this is a powerful combination.

By working with Samsung, Xiaomi, OPPO, vivo, and HONOR — the brands Indians actually buy — Microsoft is positioning Windows as the natural PC companion for the Indian smartphone user. Expect more cross-device features in future updates.
