Windows 10: Can't go back to windows 7 and i'm stucked on windows 10

so after my dad and mom buyed this pc i have no idea if this just got upgraded to windows 10 or it's literally windows 10

after a few day's i played League of Legends(its already installed in the computer)

while i was playing the computer just shuted itself and something pop up "sorry,there was a problem on your computer,we are trying to repair it now and restart the computer",then after the scan i opened the game again and when i reconnected to the game the performance is super slow i don't know what happened i tried everything in the settings(in the game)and NOTHING HAPPENED still the same,its super slow,i tried to play other games like C.O.D,left 4 dead etc...and guess what still the same..


After a week i started to search for solutions for my gaming problem,then a friend of mine said that windows 10 are not good for gaming because of its high standards or something and he said to just go back to windows 7,and i tried to do it,and this is where my second problem began,the file i needed was gone and so this came "We're sorry, but you can't go back. The files we need to go back to a previous version were removed.",so i searched everything again hoping for solutions i did saw one solution,and it was the product key of the old version of windows and it didn't work and said "sorry your product key is invalid"(i used the product key the one on stickered on the cpu)annddd finally asked windows support about this and gave me a reply

"Select the Start button > Settings  > Update & security > Recovery. Then select Get started under Go back to the previous version of Windows 10"but hey what do you expect it didn't work on my windows saying "there was no problem on your computer,no changes we're made"

and here i am still finding answers while being stucked on windows 10

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

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 Snipping Tool on Windows 7

All it is is one extra step beyond what is native to windows 10. Yes, technically it would be easier to have the functionality of print built in to the Windows 7 version, but you just have to save it ,and right click on it ,and print.

As far as getting the windows 10 version into windows7. I know there was a way to get the old winpaint, so maybe there's a way to get the snipping tool into 10, I don't know.

im curious if i could compress, and upload the application to this post? 7zip doesnt seem to be allowed
