Microsoft Surface Diagnostic Toolkit has stopped working

Okay so I was able to update Windows to v1803 latest build and ran the Surface Toolkit. It did the repair and restarted. However every time I tried to run it again (more than 5 times), it asked to restart the Surface. How can I fix this?

I also remember the last time I ran the Diagnostic toolkit for a Surface Pro 3, it went through all kinds of tests i.e. screen, touch, keyboard, battery, etc. Is it still possible?

What was the issue you needed the SDT to fix?

The current versions of the SDT probably don't work with older build 10586.

Thank you! I bought it used online so I want to check if there is anything wrong with it. What other options do I have? How can I update Win 10 Pro to a newer version?

The first thing to do is wipe and reimage. You don't know what software problems

a used device purchased online might have and this will get you to a good, known

state. You will have to register or enter the serial number. Choose the newest

recovery image available after you go to

https://support.microsoft.com/en-us/surfacerecoveryimage

(with a different Windows computer if yours is not working properly)

and download a recovery image for your Surface. You will need a 16GB USB stick

formatted FAT32 (use a Windows computer). Use FULL format and not quick format.

Give the volume a name like surfboot.

Unzip/extract the recovery zip to the formatted USB stick and then-

To reset your Surface from a USB recovery drive:

Step 1:    Make sure your Surface is turned off and plugged in (hold down the power

button for 30 seconds).

Step 2:     Insert the USB recovery drive into the USB port on your Surface.

Step 3:    Press and hold the volume-down button while you press and release the

power button on your Surface.

Step 4:     When the Surface logo appears, release the volume button.

Step 5:    When prompted, select the language and keyboard layout you want.

Step 6:     Select Troubleshoot > Reset your PC.

If prompted for a recovery key, select Skip this drive at the bottom of the

screen.

Step 7:     Select the target operating system you wish to reset. This

refers to the current operating system installed on your Surface.

Step 8:    Select Yes, repartition the drives, and on the next page, select Next.

Step 9:     Choose Fully Clean.

Step 10:    Select Reset.

Surface restarts and the Surface logo displays while the reset process continues

(this can take a while).

You could then go to https://www.microsoft.com/en-us/software-download/windows10

and select Update Now to get to the latest version of Windows. After that, go to

Settings, Windows Update, and check and install updates until no more are

available.

Thank you! I'm doing it now
