Hello and welcome to justanswer, My name is ***** ***** i will be assisting you today,
what is the model of your dell tablet (full name of your tablet) and what is your actual operating system please (windows 7 or 8) ?
Please go to www.windows.com/windows10specs and sign in. If you are not, sign up for free.
Click Continue at the bottom of the page. Click "Start upgrade now." Your browser will download a small executable to get the installation started.
Open the file you just downloaded. Click the Restart button which appears after you wait a couple of minutes for it to prepare the installation.
After your tablet restarts, it will take you to the Windows Update screen. Now all you have to do is hit install.
Your tablet will then download the 3GB Windows 10 Preview build from Microsoft and start the installation process. This can take 10 minutes or more, even with a high-speed connection
accept the terms and Click Install. The system will spend a few more minutes preparing to start for the first time and then you will be ready to use Windows 10.
