    Laptop Preinstalled 8.1 upgraded to win10, need to reinstall os.


    Hello. I am trying to recycle a laptop to my nephew and wanted a clean/fresh install. It was originally a win8.1 then upgraded to win10. Ive tried unsucessfully to reinstall windows 10 using a flash drive created with the win10 tool. But I keep getting an error about corrupt install file. Tried 2 different usb drives and reinstalled the tool multiple times.

    Do I have to install 8.1? Can I upgrade it to 10 if i do? I do not want to fumble around and end up invalidating my copy of windows.

    :)

    OS reinstall needed after upgrading CPU?

    You didn't understand it at all... You think that SSE matters me most... I want to know the behavior of the OS if it really knows that it is a different CPU and energy saving, Speed Step, Core Boost features also work... as on Penryn not Merom... Bitwise the bitset flags for cpu are compatible... therefor they work...

    Same could be also seen when upgrading to Bulldozer from older K10.5 gen, as it also introduces new instruction sets and features...

    So again... I want a solid answer.

    Yes - I've replaced CPU benched, after OS reinstall it benched faster and Battery lasted longer etc...

    NO - OS reinstall isn't need, M$ are cool cats and their win 7 OS is aware of fundamental hardware changes.

    OS reinstall needed after upgrading CPU?

    There are no core boost features in either CPU, speedstep will work regardless as it's an underlying issue that is taken care of in the bios, look in CPU-Z does it tell you what instruction sets the CPU has? yes: good then you are set to go /thread.
