Or maybe they will launch Win 12 with optional TPM support.
Imho making the OS(es) TPM only cannot be good for their business, many people are still on Win 10 with no intention to switch, since their motheboard does not support TPM and do not want to upgrade PC / waste PCI-E slot on TPM extension.
Windows Update gets turned off yes.
But you wait say 6 months and then it back on, Do all updates and then run the playbook again (after it’s been hopefully updated)
Don’t do this. Running unpatched software is a recipe for disaster.
