As mentioned in the Magento 2.2 official documentation that OS requirement is Linux, then can anyone please let me know if we can install or use the Magento 2.2.x on Windows machine or not?
If we can install the Magento 2.2 on windows then what is the correct process and what are the disadvantages if any?
as mention by @muk_t Definitely you can install magento 2 - on windows system , using wamp and xampp server.
To install magento 2 on wamp server here i am sharing reference link for the step by step installation which might helps you - https://www.simicart.com/blog/install-magento-2-wamp/
Also i completely agree with the @muk_t that problem with the windows system is magento 2 running slow , but if you have SSD instead of HDD in your windows system with proper memory configuration that you will not face that much slow issue. so its depends on the system.
Hope it helps
