From what’s been shared so far, Windows 11 26H1 seems stable on the new Snapdragon X2 devices it was designed for, but it’s not really meant for regular Intel or AMD PCs. Most users won’t notice major new features yet since this release is more focused on under-the-hood optimization and future hardware support rather than a big visual upgrade.

The version you installed—Windows 11 25H2 Build 26200.8457—is what is known as an "optimized" or "custom" image, not an official release directly from Microsoft in its original form. These kinds of builds are created by third parties who take Microsoft's original system and then modify it by removing unwanted components.

For your specific situation—wanting to save resources on a PC with modest components—this type of system can be a very good and effective choice.
