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

When you reinstall the Windows operating system, it depends on how you perform the installation whether a new partition is created or not. 1. **Clean Installation:** If you perform a clean installation and choose to format the existing partition where Windows is installed, the old data will be erased, and the installation will take place on that existing partition. In this case, no new partition will be created; instead, the existing partition will be repurposed for the new installation. 2. **New Installation on a New Partition:** If you choose to install Windows on a new partition that you manually create during the installation process (for example, if you're using unallocated space on your drive), then a new partition will be created. 3. **Upgrading or Repairing Installation:** If you are upgrading or performing a repair installation, it typically does not create a new partition. It replaces the files in the existing Windows partition while keeping your applications and data intact, depending on the method used. 4. **Using Different Drives:** If you choose to install Windows on a separate physical drive or configure a dual-boot setup, that will result in a new partition for the new installation. In summary, whether a new partition is created or not during a Windows reinstallation depends on your installation choices. If in doubt, always back up your data before proceeding with any installation.
