I used Ccleaner, updated and reinstalled drivers, uninstalled and reinstalled all necessary programs, I uninstalled my antivirus hoping it will fix the issue.
My computer was running sluggishly, so I tried everything I knew in order to get it to work again.
I then decided to clean install Windows 10 and fortunately, It worked and I felt dramatic changes in overall performance and speed.
In today’s tutorial, I will be teaching you How to clean install Windows 10 after upgrading from Windows 7 or Windows 8.
Let’s get started with the essential things.
Things You Need To Do Before Clean Install Windows 10
Though, Windows 10 installation process takes 30 to 40 minutes to be completed. But there are few very important things you must take into account before going for a clean install.
You need the ISO image file of Windows 10 and a USB flash drive
You need to have the ISO image of Windows 10, a USB pen drive with a minimum of 8 GB of free disk space. You can also burn the ISO image to a DVD disk If you want. But I personally suggest you use a USB pen drive.
Backup your data stored in USB flash before clean install Windows 10
The most important thing is your data stored in partition C. Clean installation wipes out all files and folders from Drive C. Therefore, don’t forget to back up or move your important data to any other hard drive partition, external hard drive, or USB pen drive.
Write down Windows 10 product key and license keys of programs If you have
After the clean install, Although You don’t need a product key If you have upgraded from Windows 7 or Windows 8. But You need to activate your copy of Windows 10 and other softwares you’ve bought.
Just to be on the safe side, Write down your product key and serial keys of softwares you’ve bought.
As well as you can do so with Wi-Fi key. You can use a key finder to swiftly find the Windows product key and serial keys If you don’t remember or know of.
In addition, If you don’t use a Firefox or Chrome account, then the important thing is that back up bookmarks, usernames, passwords, and other details If you use the internet.
Download all necessary drivers/make drivers DVD ready
As you might know that a computer is a set of various devices and you need to install drivers to make them operational after a new or clean install.
Download all necessary drivers to avoid any inconvenience. Specifically Wi-Fi drivers.
You can use Windows 10 media creation tool or direct download it from the official Microsoft website. I recommend you use the media creation tool to download Windows 10 installation files to make a bootable DVD or USB.
Download the Windows media creation tool from hereand launch it.
16 GB free disk space in Drive C is required to download Windows 10
Keep in mind you need 16 GB of free disk space in Drive C. Apparently there is no option to change the download location. Click accept.
Since You are going to clean install therefore select create media for another PC and click Next.
If you want to clean install on this PC you are using right now then leave it as it is. Otherwise, Remove the checkmark from use the recommended options for this PC, If you want to download it for another PC. Select your preferred language.
The most important thing you need to take into account is, download Windows 10 version you bought or upgraded to.
I’m using Windows 10 Professional edition and going to select Windows 10 from the drop-down menu. Windows 10 option contains Home and Pro editions.
Select both from the Architecture drop-down menu and click next.
Choose the USB flash drive option If you want to make only a bootable USB. You need a USB flash drive with 4 GB of free space. I recommend you use an 8 GB USB flash drive.
If you want to save the ISO image on the hard drive for future use or to burn it to a DVD disc then select the second option ISO file and click next.
Now select the download folder and give it a name If you want and click Save.
Congratulation, the Download is now complete. We now need to make a bootable USB If you had chosen the ISO file option. You don’t need to make a bootable USB If You had chosen the USB flash drive option.

After the format is complete, Select Drive C and click Next to install Windows 10.
