Windows settings that actually improve performance
Plenty of “speed up Windows” lists are padded with tweaks that do nothing on modern hardware. These are the ones that actually help, honestly ranked — and a note on when to stop bothering.
1. Trim startup apps (biggest win)
The single most impactful change. Settings > Apps > Startup — disable High-impact items you didn’t deliberately install (updaters, chat apps, launchers). Too many startup apps can slow boot by a third or more. Leave Microsoft and driver entries alone.
2. Set the power mode
Settings > System > Power & battery > Power mode → Best performance when plugged in. On a laptop, balance this against battery life.
3. Turn off visual effects (on modest hardware)
If your PC has 4–8 GB of RAM, integrated graphics or an older CPU, disabling animations and transparency helps it feel snappier:
- Search “Adjust the appearance and performance of Windows” → Visual Effects → Adjust for best performance (or keep a couple you like).
- Or Settings > Accessibility > Visual effects → turn off Animation and Transparency.
Honest note: on a modern PC with 16 GB+ RAM and a decent GPU, this barely matters — skip it and don’t expect a difference.
4. Limit background apps
Settings > Apps > Installed apps > an app’s ⋯ > Advanced options > Background app permissions → Never, for apps that don’t need to run in the background.
5. Free up disk space
Keep the system drive under ~90% full — Settings > System > Storage > turn on Storage Sense. A cramped drive slows everything.
The tweaks that actually matter most aren’t settings
Be honest with yourself: if the machine is genuinely slow, the big wins are hardware — an SSD if it still has a hard drive, and more RAM. No settings tweak beats those. See why your laptop is slow and making an old computer usable again.
What to avoid
Skip registry “cleaners,” “game boosters” and third-party optimisers. They rarely help, sometimes break things, and several are the scareware this site warns about. Everything worth doing is built into Windows.
Frequently asked questions
Does disabling animations make a real difference?
On older/low-RAM machines, a noticeable one in responsiveness. On modern hardware, negligible.
Is the “Ultimate Performance” power plan worth enabling?
Marginal for most people, and it hurts laptop battery life. Best performance mode is enough.
Should I disable Windows updates to speed things up?
No — that trades security for a tiny, temporary gain. Schedule active hours instead so updates don’t interrupt you.
