I have been having the same issues with my PC.computer fried and took the mobo, an HDD and one of my SSD's with it. Lost everything. I have had a Microsoft Account for around 15 years. I tried the instructions you gave earlier but 8.1 tells me it cannot locate 'service.msc'. Any other ways to pull up the sign-in assistant?
