Subject: Invalid "feature set" registry key
Posted: 16 February 2018 at 10:27pm
I'm guessing this is data based on information from the CPUID instruction and read at boot time and is nothing to worry about.
Regedit says invalid data because it is not 4 bytes (the size of a DWORD) but Windows code that uses this value should be unaffected. 3rd-party code might fail if it verifies that the data is exactly 4 bytes. The format of this data is undocumented.
There is no performance impact, it either works or it does not. The registry itself does not care if the data does not match the REG_* type.
