It's OK to use we recommend to introduce a Microsoft recommendation. Don't use Microsoft recommends or it is recommended.
Don't use recommend when something is required.
Examples
Windows 10 requires 16 GB of hard drive space for 32-bit OS and 20 GB for 64-bit OS.
Small
storage devices, like devices with 32-GB hard drives or older devices
with full hard drives, might require additional storage to complete
the upgrade. If you have limited hard drive space available, we
recommend that you have a USB flash drive handy when you install
Windows 10.
