Now select Install Now and this will pop up an agreement window select yes and click on the Next button The installation process takes place it will take a few minutes for installation. Once installations have been successful, we can close the installation window.
Now we can check the version in the CMD terminal by simply typing the below command. PIP is the abbreviation for Python package index which is used for installing, upgrading, or removing the extra libraries from your system.
You can upgrade the PIP by using the below command.

Go to software community server and select the current version for Windows and this MSI is the package that will install everything that I need on my computer click download it will take a few minutes to download. Once downloading is completed.

Double Click on the MongoDB exe file the installation pop-up will appear then select next, and check the agreement checkbox.
select next to do a complete installation, and don’t touch anything there everything is done for you by default so just click the next button.
To install MongoDB compass check the “install MongoDB compass” checkbox and click on the Next button the installation will take place. It will take a few minutes for installation.
After successful installation, the MongoDB compass is running automatically. If you didn’t get the compass running automatically you can just go to the window search and search for a compass when you click on the MongoDB compass button you will get to the MongoDB compass window.
Here so let’s check if everything is running fine we should be able to connect to the database and now we have these three default data databases created for us don’t ever touch them those are the default.
