Today, with the improvements in technology, the workload on a system also increased. Sometimes, our system can’t handle these workloads, and it becomes slow and starts to lag. This generally happens due to the shortage of RAM.

However, the good thing is that Windows provides a few features that can help you speed up a slow computer. So, before upgrading to new hardware, it’s always best to try software-based optimizations.

So, in this article, we will share the few best tricks that would help you speed up a slow computer. Let’s check out.
