How to Make a Slow Laptop Usable Again (Free, in About 20 Minutes)

You press the power button, walk to the kitchen, pour your coffee, come back —
and your laptop is still on the spinning dots. Double-clicking Chrome buys you time to read the
mail. Everybody says the same thing: buy a new one. Not yet. Almost everything that makes a
4-year-old laptop feel dead is free to undo, and the clicking takes about 20 minutes.

First, decide which kind of slow you have

Two problems hide behind “it got slow,” and they take opposite fixes. Watch your machine for 30
seconds and pick your row, or you will tune something that was never the bottleneck.

Step 1: Shut off the programs that open themselves

While you stare at that circle, 10 to 20 programs are loading ahead of you: the printer helper,
the updater for something you open twice a year, the chat app you signed into once. Your desktop
waits last in line. Five minutes.

Windows 11: press Ctrl + Shift + Esc for Task Manager, then the
Startup apps tab. Click the Startup impact column header to
sort. Every line reads High impact, Medium impact,
Low impact, None or Not measured. Select each
High impact app you do not need the second you log in and press Disable.

Mac: Apple menu → System Settings
→ General → Login Items & Extensions. Under
Open at Login, click the app, then the − button. The
section below it holds the ones that run all day: App Background Activity on
macOS 26 Tahoe, Allow in the Background on macOS 15 Sequoia and earlier.

Step 2: Give your drive room to breathe

A nearly full drive drags everything, and it is the top reason updates fail. Microsoft asks for
6 GB – 11 GB or more of free space for a feature update and
2 GB – 3 GB or more for a monthly one, and Apple’s slow-Mac page also lists low
free space first. Budget 8 minutes.

Windows 11: Start → Settings →
System → Storage. Turn on Storage Sense
so it keeps cleaning by itself, then open Cleanup recommendations on that same
screen. Four groups appear — Temporary files,
Large or unused files, Files synced to the cloud and
Unused apps — each showing how many gigabytes it frees before you agree. Tick and
press Clean up.

Mac: Apple menu → System Settings
→ General → Storage →
Recommendations: Store in iCloud,
Optimize Storage, Empty Trash automatically. Apple publishes no
hard number, but macOS 26 Tahoe upgrades have needed roughly 35 GB to 60 GB of free space depending
on the version you are coming from — keep 40 GB free and the update will not stop
on you.

Step 3: Finish the update that has been half-done for weeks

A machine stuck mid-update retries all day, spending your drive and processor on a job that
never lands — you feel it as a laptop that is busy while you are not. Plug in the charger and climb
this ladder, stopping the moment it goes through. About five minutes of clicking; the rest installs
on its own.

1. Start → Settings →
   Windows Update → Check for updates. Install,
   restart.
2. Still failing? Settings → System →
   Troubleshoot → Other troubleshooters, find
   Windows Update, press Run. It hands you to the
   Get Help app — normal, not a broken button.
3. Still failing? Settings → System →
   Recovery, and under Fix problems using Windows Update press
   Reinstall now. It lays the same Windows over itself and, per Microsoft, leaves
   your files, settings and apps alone.

On a Mac: System Settings → General
→ Software Update, then Update Now,
Upgrade Now or Restart Now, depending on what is waiting. It
asks for your administrator password first. If it swears you are current and the Mac still crawls,
press Check for Update, or hold Command and press R to force a fresh look.

If your Settings app has a section called “Update & Security,” read this

That wording means Windows 10, and plenty of 2022 laptops still run it. Consumer Extended
Security Updates end on October 13, 2026 — about five weeks from now. And if you never enrolled in
that free extension, your patches already stopped on October 14, 2025. Your laptop keeps working
either way and stops getting security patches — which matters more than every speed tip here. Open Windows
Update on that screen and see whether the free Windows 11 upgrade is offered to you. That
decides your evening.

Step 4: Your browser is probably the real hog

If the desktop arrives fast and then programs crawl, this is your section. Those 42 tabs are not
waiting politely. Each holds memory, and when memory runs out your laptop shuffles data onto the
drive — that shuffle is the gap between your fingers and the screen. Three minutes.

Chrome (Windows and Mac): Settings →
Performance. Turn on Memory Saver and pick
Moderate, Balanced (recommended) or Maximum;
Chrome sleeps unused tabs and wakes them when you click back. Keep your webmail and your bank under
Always keep these sites active.

Edge: Settings and more (…) →
Settings → System and performance. Switch on
Save resources with sleeping tabs, then set
Put inactive tabs to sleep after the specified amount of time to
30 minutes. The battery control there reads
Energy saver — Efficiency mode in older versions.

Safari: no memory saver and no tab-sleeping switch. Closing tabs is your only
lever, and any article telling you to turn memory saving on in Safari is describing a button that
does not exist.

The part every other article gets wrong

The honest version: exactly one part swap transforms an old laptop — a mechanical hard drive
replaced by an SSD. On a 4-year-old machine that SSD is almost certainly already inside; by 2022 a
spinning disk in a new laptop was a budget-shelf exception. “Just put an SSD in it” is how you
spend $155 swapping an SSD for another SSD and feel nothing.

So measure before you shop. Sixty seconds: press Start, type
Defragment and Optimize Drives, open it, read the Media type
column. It says one of two things.

1. Hard disk drive — you are in the minority, and that swap is the best thing
   you can do to this laptop.
2. Solid state drive — stop shopping. No part saves this machine; your answer
   is in the four steps above.

On a Mac, do not even check. Apple has soldered the drive down since the 2016 MacBook Pro with
Touch Bar, and on Apple Silicon it is encrypted to the M-series chip as well. There is no part to
buy. Read Activity Monitor → Memory →
Memory Pressure instead: green means your Mac uses its memory efficiently, yellow
that it might eventually need more, red that it needs more. Red all day, after these four steps,
means the honest answer is a different Mac.

And the price line you have read a hundred times aged badly. In September 2026 the cheapest
960 GB SATA drive on the trackers — a Kingston A400, the largest that model is made in — was
$155.00. The same drive sold for around $54 in 2024, before NAND contract prices rose 55% to 60% in
a single quarter at the start of 2026. So the swap still pays for itself on a machine with a
spinning disk; it is no longer the $50 afternoon the old articles promise. Memory is worse: a 32 GB
laptop DDR4 kit that ran about $50 in early 2025 costs $150 to $240 now, which is why “add more
RAM” stopped being advice.

Do the four steps tonight, in order, before you price a single
laptop. Then run the Media type check — those 60 seconds tell you whether
you own a $155 fix or no fix worth buying. We send one plain-English guide like this every week;
