Each time I reinstall windows 10, does it create a new partition

When you reinstall Windows 10, whether a new partition is created depends on how you choose to perform the installation. Here are the common scenarios: 1. **Custom Installation with Formatting**: If you select the partition where Windows is currently installed and choose to format that partition during the installation process, the existing data on that partition will be erased, and a new, clean installation will take place on that partition without creating a new one. 2. **Upgrading or Repair Installation**: If you choose to upgrade your existing Windows installation without formatting the partition, the existing OS files will be replaced, but your personal files and applications may remain intact, and no new partition will be created. 3. **Creating New Partitions**: If you choose to install Windows on a different partition (one that does not currently have Windows installed), or if you manually create a new partition during the setup process, that will create a new partition. 4. **Using Disk Management or Installation Media**: If you utilize disk management tools or the Windows installation media to create a new partition before installation, a new partition can be created. In summary, reinstalling Windows 10 does not automatically create a new partition; it depends on your choices during the installation process.
