What is Windows 11 Installation Assistant About?
Windows 11 Installation Assistant, developed by Microsoft, is a free tool that upgrades Windows 10 (version 2004 or higher) to Windows 11 or updates Windows 11 to the latest version, currently 24H2 (October 2024).
It checks hardware compatibility (e.g., TPM 2.0, Secure Boot), downloads 9 GB of files, and installs the update while keeping your apps and files intact.
For Windows 11 users, it bypasses phased Windows Update rollouts to get 24H2’s modern interface, improved File Explorer, and AI features like Recall for Copilot+ PCs.
If regular updates aren’t working or keeping your Windows 11 system up to date, I personally recommend using the Windows 11 Installation Assistant to manually install the latest version.
And if you’re still on Windows 10 and your PC meets the system requirements, this tool can also upgrade you directly to Windows 11.
