Well, you have no choice but to do a clean install unless someone has a workaround that I don't know about.
With a fixed ISO you can install it on 1st gen too Win 11 Boot And Upgrade FiX KiT (v5.0 Released!!!)
Really busy man (tm) question: Which is the best Windows iso available? Installed Windows 11 IoT Enterprise LTSC 24h2 when it became available, really liked it, despite the s**tty calculator and the gamebar issue (Any fix for those btw?). Sadly, I have to reinstall from scratch. Thanks for the info!
Ironic you asked this because I just did this coming from a 7700k. I used the registry key described here, no issues: Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup Name: AllowUpgradesWithUnsupportedTPMOrCPU Type: REG_DWORD Value: 1
big loss it is bloated with so call security slow your whole PC down nothing really exciting or different on 26100.XXX stay on 23/H2
I always do the modification with the file "mcupdate_GenuineIntel.dll" for performance (removed with 11 23h2, modified with 24h2)
How to Check if VBS is Enabled in Windows 11 or 10 Open system information. ... Scroll down to find the "Virtualization-based security" row. ... Search for Core Isolation in Windows search and click the top result. Toggle Memory Integrity to off, if it was on. ... Reboot your PC as prompted.
To regain performance, I rename mcupdate_AuthenticAMD.dll to mcupdate_GenuineIntel.dll and mcupdate_GenuineIntel.dll to mcupdate_AuthenticAMD.dll Of course, the related security patches are no longer operational.
