  1. I have been using Philip”s guides for my Dell Inspirion 1525 since I found them a couple or so years ago. This was a Vista OS 32 bit machine with a 64 bit capable Intel Dual Core. The laptop was given to me as it was inoperable. i diagnosed a hard drive failure. (Probably due to the heat being generated by the Vista OS.) I upgraded to a 250 gig SSD and 4 gigs of Ram and a Windows 8 and later 8.1 64 bit OS. I am now running Windows 10 64 bit. The 1525 is running better than ever especially as I finally ditched Edge and Internet Explorer in favour of Firefox which works great in tandem with Windows 10. I have yet to use any other drivers apart from those downloaded bu Windows 10. (I may change the Audio Driver as the sound is rather weak at this time.)

    Thank you Philip for all your hard work.

    1. Please can anyone give a step by step tutorial on how to upgrade dell inspiron 1525 32bit windows 7 to 64bit windows 10

      1. You cannot perform a cross-architecture upgrade – you must clean install, if you already have a Windows 7 Retail key (this system should have came with Windows Vista OEM as it as released before Windows 7) then you can simply download Windows 10 TH2 installation media and clean install with your Windows 7 Retail Key.

        Follow the instructions here:
        And here:
        Note this system has a legacy BIOS which should be updated to the latest version A17 before clean installing Windows 10 TH2 64 Bit.

  2. All I want to know is how old this laptop is.
