Built and maintained by Microsoft itself, this lightweight app can manage all segments of the important Windows update procedure on the user’s home, school, or work PCs (desktop, laptop, or tablet).

However, while it can install a new OS, it depends on the standalone “PC Health Check” app to provide a clear indication of whether or not its hardware specification and present security features are rated as acceptable for the installation of the latest version of Windows OS.

Every time Microsoft releases a brand-new version of the Windows operating system, users from all around the world have several ways to upgrade to it.

They can use a bootable external drive with the preinstalled official ISO of the Windows OS, or use the built-in “Check for Updates” tool found in Windows 10 to check if the update is available. Win11 Installation Assistant utility can manage this upgrade procedure in a fast and reliable way, ensuring that all users' data is preserved and accessible inside the new OS release.

However, in order to check for the minimum system requirement, users first have to download a standalone “PC Health Check”  in order to get a clear notification if the new version of the OS can even be installed.

This assistant is for those who wish to:
