Hi Michelle!
Thanks for reaching Microsoft Community. We're here to help and let's work on this together.
With your query on how to Un sync, to Un sync your Surface Pro 9 from your laptop, you can follow these steps:
- Go to the Start menu on your Surface Pro 9 and click on the Settings icon (gear icon).
- In the Settings menu, click on Accounts.
- Under Accounts, click on the option that says "Sync your settings."
- Turn off the toggle switch for "Sync settings" to disable syncing between your Surface Pro 9 and your laptop.
To clear the contents and start over, you can perform a factory reset on your Surface Pro 9. Please note that performing a factory reset will erase all data and settings on your Surface Pro 9, so make sure to back up any important files before proceeding. This option reimages the entire device, including the partition on the hard drive. It is the most complete form of reset. Before you begin, you must have at least an empty 16GB/32GB of USB Flash drive and it must be formatted to FAT32 prior to downloading the Recovery Image.
To proceed, please follow the detailed instructions in Creating and using a USB recovery drive for Surface - Microsoft Support.
Please let us know with how it goes. We look forward to hearing from you.
Regards,
RodelioP.
