Error raised when emulating Windows EXE on a Linux machine.

Describe the bug I am trying to run the demo code from the documentation regarding emulating an Windows EXE on a Linux machine and it is raising QlErrorFileNotFound.

Sample Code

from qiling import *

def my_sandbox(path, rootfs):
    ql = Qiling(path, rootfs)
    ql.run()

if __name__ == "__main__":
    my_sandbox(["rootfs/x86_windows/bin/x86_hello.exe"], "rootfs/x86_windows")

The output received

Traceback (most recent call last):
  File "my_hello_windows.py", line 12, in <module>
    my_sandbox(["rootfs/x86_windows/bin/x86_hello.exe"], "rootfs/x86_windows")
  File "my_hello_windows.py", line 6, in my_sandbox
    ql = Qiling(path, rootfs)
  File "/home/andreia/.local/lib/python3.8/site-packages/qiling/core.py", line 215, in __init__
    self.loader.run()
  File "/home/andreia/.local/lib/python3.8/site-packages/qiling/loader/pe.py", line 437, in run
    self.ql.os.setupComponents()
  File "/home/andreia/.local/lib/python3.8/site-packages/qiling/os/windows/windows.py", line 67, in setupComponents
    self.registry_manager = RegistryManager(self.ql)
  File "/home/andreia/.local/lib/python3.8/site-packages/qiling/os/windows/registry.py", line 44, in __init__
    raise QlErrorFileNotFound(f"Error: Registry files not found in '{self.hive}'!")
qiling.exception.QlErrorFileNotFound: Error: Registry files not found in 'rootfs/x86_windows/Windows/registry'!

I looked under rootfs/x86_windows and there I have only bin folder. I am not able to find Windows/registry anywhere on the repo.

I have the same behaviour on all the scripts related to windows from examples.

Just a couple of mentions:

I am running qiling on Ubuntu 20.10.
I switched to dev branch and also installed qilling with pip3 from the dev branch.
I have tried to emulate rootfs/arm64_linux/bin/arm64_hello and that is working successfully.

Do you have any advice?
