So, You Want to "Upgrade" to Windows 11? Here's How to Do It Right
Upgrading to Windows 11 can be a challenge, especially if you're dealing with older hardware or unsupported systems. After wrestling with multiple machines and various upgrade methods, I've compiled this comprehensive guide to help you navigate the process successfully.
The Simple Upgrade Method
Try Flyby11 first.
If that doesn't work try Microsoft's own tools:
- Download the Media Creation Tool and grab the Windows 11 ISO in your preferred language
- Mount the ISO (it'll appear as a new drive, let's say drive E)
- Open Command Prompt as administrator
- Type
e:
to switch to the mounted drive - Run the setup with:
setup.exe /product server
For those who want more control over the process, use this extended command:
setup.exe /product server /auto upgrade /quiet /compat ignorewarning /dynamicupdate disable /eula accept /noreboot
Post-Installation Cleanup
Once Windows 11 is installed, you'll want to clean up the bloatware:
- O&O AppBuster makes removing unwanted apps a breeze
- O&O Shutup10++ helps disable privacy-invasive features
- Wintoys will help you with many settings
Dealing with Unsupported Hardware
Most of my computers are older machines with unsupported hardware, and I've found success with tools like Flyby11 and Rufus for in-place upgrades. Interestingly, as of June 4th, 2025, Windows Defender has started flagging Flyby11 for deletion – which might actually be a good sign that it's effective!
Rufus Method
If you're struggling with Rufus (like I was with creating bootable drives), try running it as administrator. Alternatively, use the Media Creation Tool to create your boot drive and add Schneegan's autounattend.xml file.
Troubleshooting Common Issues
When Upgrades Fail
Even machines with identical CPU generations can behave differently during upgrades. Here's what to try:
- Update all drivers before attempting the upgrade
- Perform a clean boot using MSConfig (avoid Safe Boot – it won't work with in-place upgrades)
- Let the process run longer – I've seen upgrades get stuck at 31% for extended periods before completing
Success Story: Dell Optiplex 9010
One stubborn 3rd-gen i7 Dell Optiplex 9010 refused every upgrade method until I:
- Installed a blank drive
- Set BIOS to UEFI mode
- Used Media Creation Tool with Schneegan's autounattend.xml
- Disabled NIC boot options in BIOS
Success at last!
Essential Preparation Steps
Before attempting any upgrade:
- Clone your drive if you have important data (use disk clone, not system transfer)
- Update all drivers to the latest versions
- Close running applications that might interfere with the process
Backup and Recovery Strategy
Disk Cloning Advice
Finding reliable free cloning software can be challenging. Here are my recommendations:
- Partition Wizard (older versions) – reboots and clones without Windows running, plus adjusts to use entire larger drives
- Avoid Hasleo for USB-attached drives – it only allows "transfer OS" which doesn't copy all files
- Rescuzilla on a Ventoy drive – perfect for cloning when Windows won't boot
Pro tip: When cloning, choose "copy/clone disk" instead of "transfer OS" to ensure all files are copied.
Optimizing with Schneegan's Autounattend.xml
For clean installations, Schneegan's autounattend.xml file is invaluable. Key settings to enable:
- Bypass TPM requirements
- Hide PowerShell scripts
- Add local offline account
- Show file extensions
- Use classic context menu
- Hide search and widgets
- Left-align taskbar
- Disable app suggestions
- Prevent device encryption
- Turn on num lock
Final Tips and Tools
- Remove annoying features: Use registry entries from Winaero to eliminate the "Learn more about this picture" icon
- File management: FreeFileSync makes moving large numbers of files effortless
- Patience is key: Some upgrades take much longer than expected – don't give up too early
Conclusion
Upgrading to Windows 11 on older or unsupported hardware requires patience and the right tools, but it's definitely achievable. The key is preparation: backup your data, update your drivers, and be ready to try multiple methods if the first one doesn't work.
Remember, if disaster strikes, you'll have that cloned drive as your safety net. Good luck with your upgrade journey!
