How to uninstall and reinstall windows 10

Hello,

Thank you for posting your concern here in Microsoft Community and welcome to the Windows 10 Family. I would like to assist you.

Please be informed that Windows 10 cannot be uninstalled like any standalone program or application. Still, if you want to revert to your previous operating system, you have to either install the Operating system using an ISO image depending upon the version and the edition of Windows you are using. You can also use the Windows 10 Rollback feature if you upgraded from a previous Operating System.

Please refer to the below link to download an ISO image of Windows Operating system to install it in your computer.

However, you would still need a product key which can be purchased from Microsoft Store in order to activate the product to be able to use it.

Hope the above information was helpful.

Thank You.

Hi Danni -

Did you do the free Upgrade, and if so is it confirmed Activated?  If so then you can make reinstallation media at Installing Windows 10 using the media creation tool - Windows Help by choosing "For another PC" and then formatting for your matching version a flash stick installer, or save an ISO to burn to DVD.

Then you can boot the installer, delete all partitions during the Clean Install Windows 10 .

For free Upgrade during reactivation it should recognize the hardware configuration from the previous Upgrade activation and allow Reinstall.  However there are some problems right now with Reinstalls of Upgrade activating correctly.  We are waiting for a solution which can be monitored in this thread.  

Thats easy and faster way :)

First step, download Windows 10 iso file use Media Creation Tool.

Take it :D

Windows 10 ISO image

Seccond step: Select: Create instalation media.

Ps. Other site having Windows 10

Next step: When you download dvd image, mount iso file and press setup.exe

You don't need a Product Key unless it won't activate, then insert your old Windows Product key in Settings>System>About after confirming you have version 1511 there.

If you have performance problems it is due to the inferior Upgrade install or Factory Install, or both.  Most tech enthusiasts would never run such an install in the first place.  If you want the best possible install which has no complaints then do the Clean Install Windows 10.

Until then you can go over the Windows 10 Install Integrity Checklist.

If you want to work with us politely and not just complain, we will help you sort out your install so it runs like ours do, which are much better than any prevous OS.
