GCP Reset Windows Password

How to reset password of a GCP Compute Engine running on Windows OS.

gcloud compute reset-windows-password servername \
--zone us-central1-a \
--project your-project-id

Output

This command creates an account and sets an initial password for the
user [firstname_lastname] if the account does not already exist.
If the account already exists, resetting the password can cause the
LOSS OF ENCRYPTED DATA secured with the current password, including
files and stored passwords.
 
For more information, see:

Migrate VM to Other Network

Here’s how to move a VM to another network.

Stop the VM.

gcloud compute instances stop server-name \
--zone=us-central1-c \
--project project-id

Migrate the VM. Use self link for network and subnetwork.

gcloud compute instances network-interfaces update server-name \
--zone=us-central1-c \
--network-interface=nic0 \
--network=your-network \
--subnetwork=your-sub-network \
--project project-id

Start the VM.

gcloud compute instances start server-name \
--zone=us-central1-c \
--project project-id
