WIndows 10 instance hostname not updating

Dear openstack,

I have installed openstack train branch, I am facing issue with windows image. all windows 10 instance dosen't get its hostname updated from the metadata,

but able to get the metadata(hostname) from inside the instance using powershell.

``` $ Invoke-WebRequest http://169.254.169.254/latest/meta-data/hostname -UseBasicParsing  ```

windows2016 instance no issue.

using the stable cloudbase-init package for preparation of windows 10 (tried bot in v1909 and v2004). windows2016 server dosen't have this issue.  if you would so kindly help us with this issue

Regards

sysadmin
