Can you update to the latest version of Windows? Before you update, it’s a good idea to make sure your PC is ready for the latest version of Windows. Not every computer can install it, since updates need certain hardware, enough storage, and the right system settings. Here’s an easy way to check if your device can get the newest Windows update and how to install it.
Step 1. Open Settings: Click Start > Settings > Windows Update.
Step 2. Check for updates: Select Check for updates. If the latest version (like Windows 11 25H2) is available for your device, you’ll see the option to Download and install.
Step 3. Review eligibility:

2. Your device must support TPM 2.0, Secure Boot, and have a compatible processor.
3. You also need at least 64 GB of storage for the installation, though Microsoft recommends 128 GB or more for smoother updates and future patches.
Step 4. Automatic updates: For Windows 11 Home and Pro editions, updates usually install automatically once your PC is eligible and has enough free space.
If you don’t see the update yet, it may be rolling out gradually. You can wait for it to appear through Windows Update or use the Windows 11 Installation Assistant from Microsoft’s official website to manually upgrade.
When updating to Windows 11, users may face issues that prevent the update from completing, such as long installation times, error codes, or even blue screens. These problems often happen due to large update sizes, insufficient disk space, slow internet connections, or background programs using system resources. Software conflicts, competing updates, and corrupted system files can also cause delays or failures. In the following section, we will explain simple ways to avoid these common Windows 11 update problems.
One major reason Windows 11 version 25H2 fails to install is not enough space on the C drive or System Reserved Partition. The update process requires free space to download files, create backups, and finish installation. If the drive is too full, the update may stop with error codes. By extending the C drive, you give Windows the room it needs to complete the update successfully.
A practical way to do this is by using the “Allocate Free Space” feature in AOMEI Partition Assistant. With this tool, you can transfer unused space from another partition, like D: or E:, directly to the C drive. The process is safe, doesn’t delete data, and is easy even for beginners. This method is especially useful for fixing installation errors caused by limited disk space. To fix the C drive full issue, the multifunctional tool also many effective solutions.
