Update Highlights
- Version/Build: KB5074105, Build 26100.7705 (24H2) and 26200.7705 (25H2)
- Key Feature: Introduces a rebuilt, unified MIDI platform with native MIDI 2.0 support and enhanced MIDI 1.0 functionality.
- Rollout Status: Cumulative Update Preview rolling out now via Windows Update for Release Preview Channel users.
If you've ever tried to use a MIDI keyboard with two music apps at once on Windows, you know the drill: close one, open the other, pray it works. That headache, along with a bunch of other audio workflow nonsense, is about to get fixed. Microsoft's latest Windows 11 preview update, KB5074105, isn't just patching a few bugs. It's tearing out Windows' ancient MIDI plumbing and installing a brand new system. For musicians and producers, this is the first real reason to get excited about a Windows update in years.
Update Overview
- Update Name: 2025-01 Cumulative Update Preview for Windows 11 Version 24H2 and 25H2
- Version/Build Number: KB5074105, OS Builds 26100.7705 (24H2) and 26200.7705 (25H2)
- Update Type: Feature update (preview) and bug fix
- Rollout Status: Rolling out now (as of late January 2025)
- Region: Global rollout, not region-locked
- Security Patch Level: Includes security updates (as a cumulative update)
Think of this as a test drive for a major new feature. It's optional, it's for Windows Insiders in the Release Preview Channel right now, and its main job is to debut the "Windows MIDI Services." That's the fancy name for the rebuilt audio backbone. It packs the usual security fixes, but you're installing it to get early access to the new MIDI tools.
Eligible Devices and Rollout Schedule
You need to be signed up as a Windows Insider and set to the Release Preview Channel. If your PC is running Windows 11 version 24H2 or 25H2 and you're in that channel, you should see the update. There aren't any special hardware requirements for the MIDI stuff beyond what Windows 11 already needs.
| Device/Channel | Region | Status | Expected Date |
|---|---|---|---|
| Windows Insider Release Preview Channel (24H2/25H2) | Global | Rolling out now | Available January 2025 |
| General Availability (Stable Channel) | Global | No timeline confirmed | Expected in a future monthly update |
India Rollout Note: Insider updates like this one land everywhere at the same time. So if you're in India and in the Release Preview Channel, it's available for you now. When it eventually ships to everyone on the stable version, Microsoft will do its usual slow rollout over a few weeks. You can always poke it manually in Settings > Windows Update > Check for updates.
New Features & Changes
Unified MIDI Architecture & Native MIDI 2.0 Support
Here's the big one. Windows MIDI Services is a from-the-ground-up rebuild. It does two huge things. First, it makes the old MIDI 1.0 stuff work better. Second, and more importantly, it bakes support for MIDI 2.0 right into the OS. MIDI 2.0 is the long-awaited successor to the 1980s-era standard, offering way more precision, expression, and smarter device communication. Until now, using it on Windows was a hack. Now it's part of the foundation.
Core Features of Windows MIDI Services
Multi-App MIDI Routing
This fixes the single biggest complaint musicians had. Before, a MIDI port was locked to one app. Want to jam in a synth plugin while your DAW is open? Tough luck. Now, multiple apps can share a single hardware device. It's a simple change that completely changes how you can work.
Built-in App-to-App MIDI (Loopback)
Another classic workaround becomes an official feature. Need to send MIDI data from one program to another, like from a notation app to a virtual instrument? The new system has native loopback built in, so you don't need third-party virtual cable software. It works on both Intel and Arm PCs.
Timestamps and Message Scheduling
This is for the devs and power users. The new SDK gives apps access to precise timing data and the ability to schedule MIDI messages ahead of time. That means tighter, more reliable sequencing for professional work.
Updated Driver Model
Out with the old driver code, in with a new Microsoft-made model. It's built for modern power management and talks to the new MIDI service much faster. One driver handles both your old MIDI 1.0 gear and new MIDI 2.0 hardware.
Cross Device Resume Expansion
This update also spreads the "Cross Device Resume" feature around. Before, it only worked on laptops with built-in fingerprint readers. Now, if you plug a supported external fingerprint reader into a desktop, you can set it up in Settings > Accounts > Sign-in options to wake and unlock your PC.
Bug Fixes
They squashed one specific bug: the Narrator screen reader sometimes wouldn't start if you were installing Windows from an ISO file.
How to Download and Install
- Make sure you're in the Windows Insider Program's Release Preview Channel. Check under Settings > Windows Update > Windows Insider Program.
- Go to Settings > Windows Update.
- Hit Check for updates. Look for "2025-01 Cumulative Update Preview for Windows 11 Version 24H2/25H2 for x64-based Systems (KB5074105)".
- Click Download and install.
- Let your PC restart.
Before you click install: Plug in your laptop, connect to good Wi-Fi, and make sure you've got 5-10 GB free. Backing up your important files is never a bad idea before any big update.
Don't see it? Double-check your Insider channel is set to "Release Preview." The rollout is staggered, so it might take a day or two to hit your machine. You can force it with manual commands, but that's a path for people who are comfortable in the Command Prompt.
Should You Update Right Away?
Yes, install it now if... your work involves MIDI cables, audio software, or music production. This is a transformative update for that workflow, and testing it early is worth the potential hiccups of a preview build. Also update if you use Narrator with ISO installs.
No, hold off if... this PC is for anything mission-critical where stability is everything. You're not making music on it. You just need it to work. Wait for the stable public release. The MIDI revolution can wait a few more weeks for you.
Frequently Asked Questions
I'm not on the Insider Program. When will I get the new MIDI features?
Microsoft hasn't said. It'll ship to everyone in a future monthly update, but there's no public date yet.
Will MIDI 2.0 work with my old MIDI 1.0 hardware?
Yep. The new system is backwards compatible. Your old keyboard will work fine.
Do I need new software to use these features?
For the basics like multi-app routing, your current apps should just work better. To get the new MIDI 2.0 perks, like higher resolution controls, software developers will need to update their apps using Microsoft's new SDK.
Is this update available in India?
For Insiders, yes, it's available globally at the same time.
Can I roll back this update if it causes problems?
You can uninstall it within 10 days. Go to Settings > Windows Update > Update history > Uninstall updates, find KB5074105, and remove it.
Will this improve latency or performance for my audio interface?
Maybe. The new driver is faster, but real-world latency depends on your specific audio interface drivers and software. This update lays the groundwork for better performance, but it's not a magic fix for every setup.
Final Thoughts
Let's be clear: for most people, this is just another update. But if you've ever cursed at Windows for fighting your creative process, KB5074105 is a big deal. Microsoft finally stopped treating MIDI like a relic and rebuilt it for how people actually make music today. The multi-app support alone is a game-changer. It's still in preview, so there might be bugs, but the wait for a modern MIDI system on Windows is officially over. The rest of the industry needs to catch up.
