the 2 gb ram you have fall within the minimum requirements for windows to function normally, but remember that it's not just that, your laptop
when executing more tasks, this same one will need more processes for which it could become a little slower, to open programs, applications, among others it will have to contribute to the performance of your laptop
Windows 10 technical preview has these requirements:
Processor: 1 gigahertz (GHz) or faster
RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
Free hard disk space: 16 GB
Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
A Microsoft account and Internet access
What is RAM and how does it work?
Let's start with the most basic elements of the question. RAM is where data is stored before processing. RAM stands for Random Access Memory, and it consists of dynamic memory chips that can be written and rewritten with data very quickly. Unlike your hard drive, however, the memory used for RAM is also volatile, meaning that it only holds onto that data while the chip is powered, so it's not designed to hold information long term.
Essentially, RAM is the memory that actually lets you work with the data needed to run programs and open files. Whenever your computer loads a program or opens a file, it opens up that data in RAM. Even your operating system uses RAM when it's running. If you want to run a program, it pulls the data from long-term storage on your hard drive to short-term storage in RAM, where it can be accessed quickly enough for smooth operation.
