Is 4GB of RAM enough for Windows 11?
When Microsoft launched Windows 11, it raised the minimum requirements for installing the operating system. One of the requirements is that the user uses at least a dual-core CPU and at least 4 GB of RAM. You cannot do much smooth multitasking on Windows 11 using just 4 GB of RAM.
So, the appropriate answer to this question is no. Microsoft is correct when it mentioned 4 GB of RAM in the minimum specifications. This is because that is the absolute minimum Windows 11 will run on. Installing and running the system will be relatively stable and won’t be completely unusable.
But with 4 GB of RAM, you can’t do much. You can perform light tasks before the system struggles, even to perform basic system operations. Consider at least 8 GB of RAM up to 16 GB.
With 8 GB of RAM, you can open programs, browse the web, get stuff done, and do a little multitasking without wearing out your computer. 16 GB of RAM is probably the best of them. It permits the use of Chrome and several programs simultaneously.
