The upcoming Windows 11 version 25H2 is a small update, not a major system overhaul. If your computer already runs version 24H2, this new update will feel more like a minor tune-up than a completely new installation.

Understanding the Small Size of the 25H2 Update
You might hear that the installation files for Windows 11 25H2 are very large, but this is only true for people who are installing the operating system from scratch. If you are simply updating from the previous version, 24H2, the process is very different and much faster. The download for this update is incredibly small, less than five megabytes. This is because it is delivered as an enablement package.
An enablement package works like a light switch for features that are already on your computer. Throughout the past few months, Microsoft has been adding the new features for 25H2 to your computer through the regular monthly updates for version 24H2. However, these features have been turned off or hidden. They exist on your system in a “disabled” state.
- The 25H2 update is essentially a tiny file that flips the switch for these hidden features from “disabled” to “enabled.”
- It does not install large new components. It only activates what is already there.
- After the small package downloads, your computer will only need one quick restart to apply the changes.
- Once it restarts, your computer’s operating system version number will change to 25H2, and the new features will be active.
This method allows Microsoft to ensure that updates are quick and smooth for the vast majority of users. Because both version 24H2 and 25H2 use the same basic system files, they can both be updated at the same time with the same monthly security patches. This keeps things simple and efficient for both you and for Microsoft.
New Features in Version 25H2
While it is an update, version 25H2 does not introduce any major features that are exclusive to it. The changes you will see are also being rolled out to users of version 24H2. The main benefit of installing the 25H2 update is that you get these features turned on immediately, all at once. Users who stay on 24H2 will still receive these features, but they might arrive gradually over several weeks through other updates.
One of the most noticeable changes is to the Start menu. You will finally have the ability to hide the “Recommended” section, which many users have requested. This gives you a cleaner, more streamlined Start menu. Another minor visual change is the introduction of more colorful battery icons, which can make it easier to see your power status at a glance. Improvements to power efficiency have also been made, which may help your laptop’s battery last a little longer. Again, all these changes will also be available to anyone using an up-to-date version of 24H2. There are no groundbreaking functions that you will miss out on by waiting.
The User Experience
If you have been using Windows 11 version 24H2 and keeping it updated, you will notice very little difference after installing the 25H2 update. The look and feel of the operating system will remain almost identical. The performance of your computer will not change, either. This also means that if you are currently experiencing any bugs or issues with version 24H2, those same problems will likely still be present after the update. This release is not focused on fixing bugs but on activating a small set of new functions.
Microsoft has also been working on making future updates smaller. The company has successfully reduced the size of monthly cumulative updates by about 40 percent. This is good news for everyone, whether you are on 24H2 or 25H2, as it means future security patches and feature tweaks will download and install more quickly.
How You Can Get the 25H2 Update
There are two main ways to install Windows 11 version 25H2 on your computer. The path you choose depends on how soon you want the new update.
Wait for the Official Release
This is the easiest and safest option for most people. The update will begin rolling out to the public in late September or early October 2025.
It will appear automatically in your Windows Update settings. When it is ready for your device, you will see an option to download and install it.
You do not need to do anything special to prepare. Just continue to use your computer and install regular updates as you normally would.
Join the Windows Insider Program
If you are an enthusiast and want to try the update right now, you can join the Windows Insider Program and select the Release Preview Channel.
The Release Preview Channel is the most stable of the Insider channels and provides early access to updates that are very close to being released to the public.
To join, go to Settings, select Windows Update, and then click on Windows Insider Program. Follow the on-screen instructions to get started.
Joining this program will not void your device’s warranty.
Once the 25H2 update is officially released to everyone, you can safely leave the Insider Program. This will stop you from receiving future pre-release software and ensure your computer returns to receiving only stable, public updates.
What About the ISO Installation Files?
You may have seen reports that the ISO files for version 25H2 are delayed. An ISO file is a large file that contains the entire operating system. It is used for performing a “clean install,” which means wiping a computer’s hard drive and starting fresh, or for installing Windows on a brand new computer.
For most users who are simply upgrading an existing Windows 11 PC, this delay does not matter. You do not need the ISO file. The update will come through Windows Update as a small enablement package. The delay in releasing the ISO files will not affect the official rollout schedule for regular upgrades. It only impacts those who need to perform a full, new installation.
