CPU ID's dont get ran because of privacy concerns. Was a big thing thing about it back in the day.
Most/all modern CPUs do not have a software-readable serial number. Intel tried to add one in the late 1990s with the Pentium III, but there was such an uproar that they discontinued this feature. The best you can do with a CPU is to identify the particular model/stepping, which CPU-Z does a nice job of.
Basically if you didnt have a Genuine Intel CPU you couldnt install an OS because M$ and Intel was in bed together and wanted to block people with test chips etc from installing an OS.
Its like people with a raid0 who would have this a serial of something generic. Vloume2 for example
Would only need to worry about Revo uninstalling and reinstalling. Currently atm they do not leave trace files. Most raid0 users will chose a generic name Volume1,2 etc MyRaid, 0000000000000 etc.
If you chose a random name with your HWID like 39824283sd9823457sadf then they will still ban you.
