Windows Installation Slow When Installing a New System
Fix 1. Check the Hardware Requirements
When you encounter the “Windows 10 installation slow” issue when installing a new operating system, the first thing should you do is check if your PC meets the minimum requirements for Windows 10.

- 1 GB of RAM for Windows 10 32-bit and 2 GB of RAM for Windows 10 64-bit.
