Whenever you purchase a new computer or laptop/notebook, it will usually have been on the shelf for quite a while and not have the latest version of Windows installed.
In addition, many computers come pre-loaded with software called bloatware. These are special offers that the manufacturer agrees to put on for software app developers.
These may include Anti-Virus products, Cloud storage products or other Applications.
These can slow down the computer and cause problems as they are also usually out-of-date.
It is entirely possible that when updates are applied, the new computer may behave erratically.
For a smooth computing experience, it is advisable to completely erase it and set it up from scratch.
This process ensures the computer experience is free from bloat and also checks the computer for any possible hardware issues.
