COVID-19 became a disaster problem globally (Dwivedi et al., 2020). This pandemic affects all sectors and probably changed the world as a new lexicon, a new social norm (Dwivedi et al., 2020). In the case of Covid-19, IT played an essential act in educational institutions by helping students to overcome the challenges and gives them a chance to apply E-learning (Khan, Nabi, Khojah & Tahir, 2020). During this quarantine time, educational institutions transferred the traditional learning process to E-learning process (Alavudeen et al., 2021). Besides, E-learning has never been adopted before the Covid-19 pandemic that obligated to apply E-learning system (Khan et al., 2020). Nowadays, during the Covid-19, the majority of the educational institutions are dealing with e-learning in order to facilitate the learning process (Khan et al., 2020).
 
Students and educational institutions globally faced several obstacles and challenges to adopt the E-learning such as communication between instructors and students, connection problems, electricity, etc. (Abbasi, Ayoob, Malik & Memon, 2020).  More attempts are needed by users to create an advanced pedagogy to improve student's learning. Furthermore, this paper is considered as one of the few studies to understand the intention of E-learning usage process in different contexts. Besides, the results of this research will enhance universities' decision makers to make their students familiar with the new technologies, software and applications included in the E-learning process and will help the organizations that work in IT domain to develop more users' friendly applications that support the educational process.
The purpose of the research is to investigate aspects influencing students' adoption of E-learning systems and to predict the main reasons behind intention of E-Learning usage. These aims will be achieved by investigating 33 empirical studies in different E-Learning contexts in a systematic manner. This paper is composed by different sections, started by the introduction, followed by the theoretical background, then the methodology. It follows by presenting a literature review in a systematic way, then the discussion and conclusions and finally future research are presenting in the end on this study.
