Like any new Program, You have to give it a chance to show you what it can do. Windows 10 is no different! Here is a link to a Introduction to Windows 10 https://www.youtube.com/watch?v=nhAKidH3s4Q It is worth a watch.
Do you need a copy of your ISO operating system try this link microsoft windows iso download https://www.howtogeek.com/186775/how-to-download-windows-7-8-and-8.1-installation-media-legally/https://www.google.com.au/search?q=microsoft+windows+iso+download&oq=microsoft+windows+ios&aqs=chrome.1.69i57j0l5.23431j0j7&sourceid=chrome&ie=UTF-8 I don’t know if there is a free one for your operating system but you can download it and keep it on a flash drive or CD Rom..
I realise some of you prefer to use earlier versions of windows, however windows 10 is easier to fix when something goes wrong provided you have a recovery USB or CD rom disc to fall back on. Even if you use earlier versions you should create a backup disc. Go To https://support.microsoft.com/en-us/products/windows?os=windows-10 for troubleshooting and upgrades..
I have been using Windows 10 since it was released as a free Programme. It has had it’s issues but overall is not a bad programme. It takes a bit of getting used to but it has it’s merits. As with the development of the PC over the years Windows Has come a long way. To get your PC to look similar to what you are used to simply Open Control Panel click on Taskbar and navigation Click Start menu turn on show app list in Start menu. Another Way to do the same thing is right click the start icon Click on settings Click on the personalisations tab And then click Start turn on show app list in start menu. Turn off and on your PC..
