Though it's been noted that Windows 10 will not bring away or move all your data while installing on your PC. However, this might confuse quite a lot of users who don't want to keep all the system drive data with them for that some old useless files may exist with the new system, taking big space in PC. And in order to gain a fast running speed, quite a lot of users prefer to clean install Windows 10. If you need to perform a clean installation of Windows 10 without losing important data, follow the below tips to install Windows 10 now.

Tip: Backup important data and files before installing Windows 10

Though it says that Windows 10 will not move all your present Windows data after the installation, however, the data stored in the system drive partition may also change and even get overwritten by the new system installation files of Windows 10. Therefore, in order to prevent data loss issues in your computer, please create backups for your PC data. And it's highly recommended for you to back up the data into an external hard drive.

If you think it's time-consuming to copy files one by one into the storage device, you may try professional backup and recovery software. EaseUS Todo Backup allows all Windows users to back up their data under Windows 10/8/7 etc with simple clicks. Download and install EaseUS Todo Backup and then follow the step below to backup your present Windows 7/8/10 data right now:

Step 5. EaseUS Todo Backup allows users to save the backup files to every device that is handy for you, like a local hard drive, external USB drive, SD card, network drive, or a NAS drive, plus a cloud drive of the EaseUS brand. We personally recommend users to choose the cloud drive prior to a physical drive to save important backups due to the greater accessibility, flexibility and safety.

To be able to access to EaseUS cloud, all you need is an email registration and login.

Step 6. If you're interested in an automatic and intelligent backup schedule for the next file backup task, go on with the "Options" setting. There you can encrypt a confidential file backup, compress the backup image size, or customize a backup scheme to tell the software in what time to start the next backup.
