As a best Windows 11 upgrade tool, this tool should work perfectly for your situation, and importantly, the search results mention FlyOOBE as the current, updated solution specifically for 2025-2026. The developer has released version 2.3 with improved performance.

How to Use The Best Windows 11 Upgrade Tool

1. Download two files:

Windows 11 ISO from Microsoft's official website.

FlyOOBE from its GitHub releases page (builtbybel/FlyOOBE).

2. Run FlyOOBE as Administrator and select the "Upgrade to Windows 11" option.

3. Point the tool to the Windows 11 ISO (drag-and-drop or browse to the file).

4. The upgrade will begin, bypassing all hardware restrictions automatically. The process takes 20-60 minutes.

5. After the upgrade completes, FlyOOBE will offer customization options where you can remove bloatware and adjust privacy settings.

Your 8GB of RAM is the minimum for a decent experience. The search results suggest that after cleanup, Windows 11 uses about 2.2GB of RAM, leaving you with roughly 5.8GB for apps. This should be manageable for basic tasks, but you may want to consider adding more RAM if you run heavy applications simultaneously.

How about trying the Hybrid USB method if you are finding a Windows 11 upgrade tool from Windows 10? This method is completely free, uses only Microsoft's own files, and has been verified by Dell community members to work on OptiPlex systems with 7th-gen Intel processors like yours.

Your Dell OptiPlex 3050 has a 7th-gen Intel processor, which Microsoft officially excludes from Windows 11. The hardware compatibility check is triggered by the contents of the install. esd and appraiserres. dll files. By swapping the installation file, you bypass the check entirely while still using 100% authentic Microsoft files.

However, some users attempt to bypass this compatibility check by swapping the installation files with modified versions. For example, replacing the install.esd or appraiserres.dll files with altered ones can bypass the check entirely. This method allows you to proceed with the Windows 11 upgrade on hardware.

It's important to note that while this technique can help you upgrade to Windows 11 from Windows 10 on unsupported hardware, compare with other Windows 11 upgrade tool from Windows 10. It also carries risks. Bypassing the compatibility check may lead to system stability issues or problems with future updates. Proceed with caution and ensure you understand the potential implications before attempting to modify installation files during the Windows 11 upgrade process.

The reason Windows Update shows nothing available is simple: your PC does not meet Microsoft's official hardware requirements, primarily because it has a 7th Gen Intel processor (i5-7500T). Microsoft only officially supports Intel 8th Gen and newer for Windows 11.

What it is: This is not an installer you run once. The best Windows 11 upgrade tool is a script that automates the process of creating a patched Windows 11 installation USB drive or ISO file.
