 | `VM::NO_MEMO` | This will disable memoization, meaning the result will not be fetched through a previous computation of the `VM::detect()` function. Use this if you're only using a single function from the `VM` struct for a performance boost. |
 | `VM::EXTREME` | This will disregard the weights/biases in the scoring system. It will essentially treat any technique that found a hit as a VM detection no matter how low that technique's certainty is, so if a single technique is positive then it will return true. | 
 | `VM::DEFAULT` | This represents a range of flags which are enabled if no default argument is provided. |
-| `VM::ENABLE_HYPERV_HOST` | Windows 11 (and 10 if enabled manually) may have Hyper-V as a default virtualisation solution for any host program even if the OS is running as host. There isn't a way to detect whether the host program is ran in default virtualisation mode, or manually intended virtualisation, which is one of the main hurdles of the library to overcome. This is a Hyper-V specific problem, and the library will discard any Hyper-V brand suspicions as not running in a VM by default. But if this flag is enabled then it will still count it regardless of the risk that it might be Hyper-V's default host virtualisation for every host program. So basically this flag means that "I'm aware this program might be running in a default virtualised environment on host, but I'll still count this as running in a VM anyway whether it's default virtualisation or manually intended virtualisation". |

There isn't a way to detect whether the host program is ran in default virtualisation mode, or manually intended virtualisation.

 | `VM::WIN_HYPERV_DEFAULT` | ⚠️ **DEPRECATED** ⚠️ Same as above, but deprecated as of 1.5 release. |
 | `VM::MULTIPLE` | This is specific to `VM::brand()`. This will basically return a `std::string` message of what brands could be involved. For example, it could return "`VMware or VirtualBox`" instead of having a single brand string output. This has no effect if applied to any other functions than `VM::brand()`. |   
 | `VM::HIGH_THRESHOLD` | This is specific to `VM::detect()` and `VM::percentage()`, which will set the threshold bar to confidently detect a VM by 3.5x higher. |
