Regular maintenance of laptops and desktop computers is crucial for their longevity and performance. Starting these maintenance tasks early and revisiting them every few weeks can prevent computers from becoming sluggish and unresponsive. If a computer is already significantly slowed down, resetting it to its original state is an option, provided all data is safely backed up.
  

Key Points 

1. Importance of Regular Maintenance: Like any mechanical device, computers benefit from regular maintenance to extend their lifespan and maintain optimal performance.
2. Timely Start to Maintenance: It’s advisable to begin maintenance tasks early in a computer’s life; delaying these tasks can lead to irreparable sluggishness and operational issues.
3. Frequency of Maintenance: Regular check-ups every few weeks are recommended to keep the computer in good condition.
4. Resetting as a Last Resort: For computers that have become extremely slow, resetting them to their factory settings can be an effective solution, but this should be done after ensuring all data is securely backed up.
5. User Responsibility: The maintenance of a computer largely falls on the user, requiring a certain level of commitment to regular check-ups and updates.
