How to Speed Up Windows 11 — 10 Proven Tweaks That Work
1. Cut down startup apps
The biggest, easiest win is reducing what launches when Windows starts. Press Ctrl+Shift+Esc to open Task Manager, click the Startup apps tab, and disable anything you do not need loading at boot — chat apps, updaters, and software helpers you rarely use. Each one you disable frees resources and speeds up startup.
Look at the Startup impact column to spot the heaviest offenders. Disabling startup items does not uninstall the programs; you can still open them whenever you like. It simply stops them running in the background from the moment you log in, which is where a lot of sluggishness hides.
2. Free up disk space
Windows 11 slows noticeably when the drive is nearly full, because it needs free space for temporary files and updates. Open Settings, System, Storage, and turn on Storage Sense to clear temporary files automatically. Remove old downloads, empty the Recycle Bin, and uninstall programs you no longer use.
Aim to keep at least fifteen percent of your drive free. On a small drive that fills quickly, this alone can transform performance. If you are constantly running out of space, that is a strong hint that a larger or faster drive would help.
3. Turn off unnecessary visual effects
Windows 11 uses animations and transparency that look pleasant but cost performance, especially on older hardware. Search for Performance, choose Adjust the appearance and performance of Windows, and either select Adjust for best performance or untick the heaviest effects like animations and transparency.
On a capable machine the difference is subtle, but on an older or lower-spec laptop it can make the whole interface feel snappier and more responsive. It is an easy, reversible change that costs nothing and is worth trying on any sluggish system.
4. Check for and install updates
It sounds counterintuitive when you are chasing speed, but keeping Windows updated genuinely helps. Updates include performance improvements and driver fixes that resolve slowdowns. Open Settings, Windows Update, and install everything available, then restart. Outdated graphics drivers in particular can cause sluggishness.
If your slowness started right after an update, the opposite may be true — a recent update introduced a problem. In that case, checking for a newer fix, or rolling back a problem update, is the right move. Most of the time, though, being up to date is the faster state.
5. Disable background apps you do not need
Many apps keep running in the background even when closed, consuming memory and processor time. In Settings, Apps, Installed apps, you can review individual apps and limit their background activity. Trimming this for apps you rarely use frees resources for the tasks you actually care about.
Be sensible about which ones — leave essentials like security software alone. But disabling background activity for the long tail of apps you barely touch reduces the constant low-level load that quietly slows a busy system.
6. Run a malware scan
Hidden malware is a classic, overlooked cause of a slow Windows 11 machine, quietly using your processor and network in the background. Run a full scan with Windows Security, and consider a second opinion from a reputable tool like Malwarebytes. Removing infections can restore speed that no setting tweak would recover.
If your computer became slow suddenly, especially alongside pop-ups or odd behaviour, treat malware as a leading suspect. A clean machine is the foundation that all the other tweaks build on, so it is worth ruling out early.
7. The upgrades that make the real difference
Settings tweaks help, but if your computer still has a mechanical hard drive, fitting an SSD is the single change that transforms Windows 11 performance — boot times drop from minutes to seconds. Likewise, a machine with only 8GB of RAM will feel tight under Windows 11, and moving to 16GB delivers a big, lasting improvement.
These hardware upgrades are affordable and often outclass every software tweak combined. If your PC is fundamentally capable but slow, an SSD and a RAM bump usually give it years more useful life. We fit both and migrate everything across, same-day, across Western Sydney.
Tweaked everything and it is still slow?
Software tweaks can only do so much on ageing hardware. An SSD and a RAM upgrade often transform a slow Windows 11 PC. TechFix Pro diagnoses the real bottleneck across Western Sydney and fixes it — No Fix, No Fee.
Quick checklist
- Disable unneeded startup apps in Task Manager
- Free up disk space and turn on Storage Sense
- Reduce visual effects for best performance
- Install Windows updates and check drivers
- Run a full malware scan; upgrade to SSD/16GB if needed
Frequently asked questions
Why is Windows 11 so slow on my computer?
Common causes are too many startup apps, a nearly full or mechanical hard drive, heavy visual effects, outdated drivers, background apps, or malware. On older hardware, limited RAM and a slow drive are usually the biggest factors.
Is it safe to change these performance settings?
Yes. Every tweak here uses built-in Windows settings and is fully reversible — no registry edits or third-party hacks. You can re-enable anything you change at any time.
Will an SSD speed up Windows 11?
Significantly, if your computer still has a mechanical hard drive. An SSD often cuts boot time from minutes to seconds and makes everything feel instant. It is the most impactful single upgrade for a slow PC.
Does 8GB of RAM slow down Windows 11?
It can, especially when multitasking with many browser tabs and apps. Windows 11 runs more comfortably with 16GB, and upgrading from 8GB to 16GB usually gives a clear, lasting improvement.
