This article explains how to update your Windows 11 device from 24h2 or 23h2 to 25h2. It offers clear upgrade paths, download methods, and tips to ensure a smooth update.
25H2 is more secure, more stable, has more features, and will be supported longer than 23H2 and 24H2. Each new version brings better performance, stronger security, and updated AI features. This is why many Windows 11 users prefer to upgrade to the latest version.
Compared with 23H2 and 24H2, 25H2 usually offers:
If you want to know which Windows version your PC is running, you can check it in Settings. Open Start, select Settings, then go to System > About. Under Windows specifications, you will see your Edition (such as Windows 10 or Windows 11) and your Version (for example, 24H2 or 25H2).
Microsoft has not officially announced Windows 12 yet. Any information about it is based on rumors, and possible release dates are only guesses. For now, Microsoft continues to improve Windows 11 with updates like version 25H2.
To get the update, go to Settings > Windows Update > Check for updates. If it’s available for your device, select Download and install. For most Home and Pro editions, the update installs automatically once eligible.
Before updating, it’s important to make sure your PC meets the requirements. Not all computers can install the newest Windows version, as updates need the right hardware, enough storage, and proper system settings. Here’s an easy way to check if your device can get the latest update and how to install it.
Step 1. Open Settings. Click Start, then Settings, and select Windows Update.
Step 2. Check for updates. Select Check for updates. If the latest Windows version, like Windows 11 25H2, is available, you’ll see the option to Download and install.
Step 3. Review eligibility. Use Microsoft’s PC Health Check to confirm your device meets Windows 11 requirements. Ensure TPM 2.0, Secure Boot, and a compatible processor are supported. At least 64 GB storage is required, though 128 GB or more is recommended.
Step 4. Automatic updates. Windows 11 Home and Pro usually install updates automatically when eligible. If the update isn’t visible, it may be rolling out gradually, or you can upgrade manually using the Windows 11 Installation Assistant.
A common reason for upgrade failures is not having enough space on the C drive or the System Reserved Partition. Windows needs free space to download update files, create backups, and finish the installation. If your drive is full, the update may stop and show error codes. Expanding the C drive usually solves this problem by giving Windows the space it needs.
One easy way to do this is by using the “Allocate Free Space” feature in AOMEI Partition Assistant. It lets you move unused space from other partitions, such as D: or E:, directly to the C drive. This process is safe, does not delete data, and is simple for beginners. It is especially effective when update failures are caused by low disk space. The tool also offers other useful options to fix a full C drive.
Since Windows built-in tools cannot extend the System Reserved Partition in all cases, using a professional partition manager is often the best solution. AOMEI Partition Assistant provides safe and flexible disk management. It can resize, move, merge, and split partitions without losing data. Its “Allocate Free Space” feature is ideal for this issue because it can transfer space from any partition and add it to the System Reserved Partition in just a few clicks.

Step 3. Click "Apply" and "Proceed" to execute the progress.
Upgrading to Windows 11 25H2 from 24H2 or 23H2 helps you get better performance, improved security, and longer support. If the upgrade does not go through, it is usually caused by low disk space or unmet system requirements. By checking your device, freeing up space with AOMEI Partition Assistant, and using the right tools, you can complete the upgrade smoothly and keep your PC running at its best.
