Windows 10: How to Get Windows 10 older ISO?

I have updated my pc to windows 10 1904 build but since i updated my pc from 1819 my mouse pad is not working while pc start then i need to use aero keys and then after opening any folder through pressing enter it will start to work properly, also boot time increse to around 7-8 minutes which took in 2017 version around 30-40 second, increased in 1819 to 2minutes and now taking upto 10 minutes and some times pc didnt start at all so i need to restart again.

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
