How to make your computer faster, and keep it that way

Anyone can make a computer fast for a week. You clear things out, it feels new, and a month later it is exactly as slow as before — which is why people conclude the machine is simply old.

It is not old. The causes of slowness refill, and each one refills at a different rate. Match your maintenance to those rates and the problem stops recurring.

What grows back, and how fast

• Browser tabs — daily. The fastest-refilling cause by a distance. A browser is open continuously, and tabs accumulate without anyone deciding to accumulate them.
• Startup programs — monthly. Applications add themselves back after updates, and new software arrives with background helpers.
• Disk space — monthly. Downloads, caches and updates fill it quietly, and the last 10% is where slowness starts.
• Dust — yearly. Slow, invisible, and eventually the reason a laptop throttles after twenty minutes.

Daily: automate the browser, do not manage it

Anything requiring daily discipline will not survive contact with a real week. This is the one to hand off.

Chrome can release the memory an unused tab is holding while leaving the tab in place, and that can run on a schedule rather than on your attention — heavy, untouched tabs get released in the background, and anything you have marked as protected is left alone. Set it once and the largest recurring cause stops recurring. How the mechanism works, if you want to understand it before automating it.

Monthly: five minutes

1. Startup list. Windows: Task Manager → Startup apps. macOS: System Settings → General → Login Items. Anything new since last month that you did not ask for, turn off.
2. Disk space. Check you are above 15% free. If not, Downloads is almost always the answer.
3. Installed applications. Remove what you stopped using — not for the space, but for the background services that came with it.

Yearly: the physical part

Clear the vents. If a laptop is fast for twenty minutes and slow after an hour, it is throttling to protect itself from heat, and dust is almost always why. On a desktop, the same applies to intake filters.

Also worth an annual look: drive health. Drives degrade gradually rather than failing cleanly, and a dying one feels exactly like a computer that has got old.

What is not maintenance

Registry cleaning, defragmenting an SSD, driver updater subscriptions and monthly reinstalls are not maintenance — they are activity. None of them addresses anything on the list above, and the first three carry real downside.

Maintenance is unglamorous: keep memory from filling, keep the startup list short, keep 15% of the disk free, keep the air moving. A machine that gets those four things stays fast for years longer than one that gets an annual dramatic rescue.

If yours is slow right now, fix it first — the checklist ordered by payoff — then come back and set up the routine so you only have to do it once.
