How to Go From Windows 10 Version 1511 to 1607: Step By Step Upgrade Process

I’ve upgraded more Windows machines than I can count, and 1511 to 1607 was one of the smoothest transitions. This jump fixed so many early Windows 10 annoyances that made daily use frustrating.

The process is straightforward but requires patience. You’ll need at least 20GB free space, a stable internet connection, and about 2 hours of uninterrupted time. I learned the hard way that skipping the backup step can ruin your week.

Using the Media Creation Tool is foolproof, but the command-line method gives you more control. Both paths will get you to 1607 with all your files intact if you follow the steps carefully.

After the upgrade, verify the version in Settings to confirm success. The difference in stability and features makes the effort worthwhile every time.

What Youll Need

Instructions

Here is the method I use to ensure a smooth transition between these builds.

Open Settings and navigate to System > About. Confirm the current version is 1511 and note your system type, either 32-bit or 64-bit. This step prevents downloading the wrong update package.

Check that your device meets the minimum requirements for version 1607: 2GB RAM, 20GB free storage, and a 1GHz processor. Most systems running 1511 will qualify, but it’s worth verifying to avoid mid-installation failures.

Visit Microsoft’s official site and download the Windows 10 Update Assistant. This tool streamlines the process and ensures you get the correct build for your system. Avoid third-party download sources to prevent malware or corrupted files.

Run the assistant as administrator. It will automatically check for available updates. When prompted, select Update now to begin downloading version 1607. The download size is typically around 3-4GB, depending on your system.

Once the download completes, the assistant will prepare the installation. Ensure your device is plugged into a power source—laptops should not rely on battery power. The process may take 30-90 minutes, depending on hardware.

Your system will restart multiple times during the upgrade. Do not power off or interrupt the process. You’ll see progress indicators like “Working on updates” and “Getting devices ready”. When complete, the login screen will appear.

After logging in, reopen Settings > System > About to verify the version now reads 1607. If the update fails, run the Update Assistant again or use the Media Creation Tool to manually install the build.

If you encounter errors, check Microsoft’s support site for specific error codes. Common fixes include temporarily disabling antivirus software, freeing up additional storage space, or using the DISM and SFC tools to repair system files.

Tips and Common Mistakes for Perfect Windows 10 Version Upgrade

Here’s what I wish I knew before upgrading hundreds of machines from 1511 to 1607.

Pre-Upgrade Check: In Step 1, don’t just confirm you’re running version 1511—actually write down your system type (32-bit or 64-bit). I’ve seen too many users download the wrong package because they forgot this detail. The 2GB RAM and 20GB storage requirements are non-negotiable; I once tried squeezing this onto a machine with 16GB free and hit a wall halfway through.

Download Strategy: For Step 2, if your internet is unreliable, use the Media Creation Tool instead of the Update Assistant. It creates a bootable USB you can use anytime. The 3-4GB download fails often on spotty connections, and nothing’s worse than watching it restart at 98%.

Power Management: During Step 3’s 30-90 minute installation, laptops on battery power have a nasty habit of shutting down at the worst moment. I learned this the hard way with a ThinkPad that died at 67%. Even if you think your battery is fine, plug it in. The multiple restarts will drain power faster than you expect.

Post-Upgrade Verification: After Step 4, don’t just glance at the version number. Open Command Prompt and run winver—it’ll show you the exact build. I’ve caught several systems that claimed to be 1607 but were actually stuck on 1511 because the update failed silently.
