My 6 year old laptop would not install the latest W10 Upgrade ( Fall Creators Update # 1709 ). Both Microsoft and Sony told me it won't because it wasn't built to handle the future W10's ( my PC is too old ).
My advice to you; is to call the free W10 Update service @ 1-800-936-5700, and tell them at first it's about Updates, not Activation---then,if you want, they will install the Upgrade for you--- or if your PC cannot Upgrade( you must give them the Model and Serial No ), they can set your PC to NOT receive anymore Updates/Upgrades.
I find the free MS service is reliable, I have used it several times before. If you cannot understand what the MS Tech is saying; go take a speed language class in Pakistani.
I opted to just buy a new laptop; you can get some good deals now on older generation Intel processor PC's, like 6 or 7th, since the newest models are coming out now with the 8th generation of Intel Processors.
