Thanks for reaching out to the Microsoft Community! I’m sorry for your loss. If you need to reset a Surface Pro without the PIN or Microsoft account, here’s what you can do:
Option 1: Use Built-in Recovery
Turn off the Surface Pro.
Hold Volume Down, then press and release Power.
Release Volume Down when the Surface logo appears.
Select Troubleshoot > Reset this PC.
Choose Remove everything and follow the prompts.
Option 2: Create a USB Recovery Drive
If built-in recovery doesn’t work, create a USB recovery drive using another Windows PC.
Step 1: Download the Recovery Image
Go to Microsoft Surface Recovery Image.
Sign in, select your Surface model, enter the serial number, and download the ZIP file.
Step 2: Prepare the USB Drive
Use a USB drive with at least 16 GB (32 GB recommended).
Format it to FAT32.
Back up any data because this process erases the drive.
Step 3: Create the Recovery Drive
Extract the ZIP file.
Copy all extracted files to the root of the USB drive.
Step 4: Boot from USB
Insert the USB into the Surface.
Hold Volume Down, press and release Power.
Release Volume Down when the logo appears.
Choose language and keyboard layout.
Select Recover from a drive and follow the prompts.
This will erase all data on the Surface. If you need to recover files first, consider professional data recovery before proceeding.
Hope this helps! Let us know if you need more details or assistance.
