2.4.0 comes with the following changes:
- Cleaned up Code
- Updated Language Files
- Fixed Command Line Switches (see below and WhyNotWin11.exe /?)
- Added New Supported Intel Processors
- Re-Added Cross for Failed Checks for Accessibility
- Removed "Unsure" Result for CPUs now that Microsoft testing is complete
- Added Note that WIndows 11 can be installed, but not updated to, if you completely delete your existing Windows 10 data
(Various other minor changes to be documented in 6-8 hours)
Note from the Programmer:
Microsoft's Business team has confirmed that Windows 11 can be installed on old hardware! The only thing you have to do is COMPLETELY WIPE your old Windows 10 install and install a clean version of Windows 11. Additionally, it appears Microsoft will be releasing a reasonably clear version of the PC Health Check tool "soon", and I expect popularity of this project to die off. If you need a feature that the new check tool doesn't have, please create an issue so I can try to fill any remaining niches!
Thank you for using WhyNotWin11
