How to speed up a slow laptop or PC with simple software fixes

A slow laptop or desktop can make even small tasks feel painful, but you often do not need new hardware to get decent speed back. A few focused software checks and settings changes can noticeably improve performance.

This guide walks through a simple checklist that works on most Windows and macOS devices. Start with the quick wins, then move to deeper fixes only if you still feel the system dragging.

Check what is slowing your computer right now

Before changing settings, see which apps and processes are currently using the most resources. On Windows, pressCtrl + Shift + Escto open Task Manager. On macOS, openActivity Monitorfrom Applications > Utilities.

Sort by CPU, Memory and Disk. If one app is consistently at the top and pegging usage, close it and see if performance improves. If it is a browser tab, try closing heavy sites like streaming, online editors or dashboards.

Reduce auto-start apps and background tools

Many programs quietly add themselves to startup, which slows boot time and keeps memory busy for no good reason. Trimming this list often delivers one of the biggest improvements.

On Windows, openTask Manager > Startupand disable anything you do not need all the time, such as chat apps, game launchers or helper tools. Leave drivers, security software and trackpads or keyboard utilities enabled.

On macOS, go toSystem Settings > General > Login Items. Remove or toggle off apps that are not essential when the system starts. You can always launch them manually when needed.

Clean up disk space and temporary files

Very low free disk space can slow the system significantly, especially on older drives. Aim to keep at least 10 to 20 percent of the main drive free where possible.

On Windows, openSettings > System > Storageand enableStorage Senseto automatically delete temporary files and empty the recycle bin. You can also use theCleanup recommendationsor a manualDisk Cleanupto remove old update files and logs.

On macOS, click the Apple menu, chooseAbout This Mac > Storage > Manage. Use options likeEmpty Trash Automatically,Reduce Clutter, and move large, rarely used files to an external drive or cloud storage.

Uninstall unused programs and browser extensions

Old apps can add background services, context menus and update tools that you never use. Removing them can simplify the system and free resources.

On Windows, go toSettings > Apps > Installed appsand remove software you no not recognize or no longer need. Be cautious with items from hardware vendors or anything labelled driver or runtime components, as the system or other programs may rely on them.

On macOS, drag unused apps from the Applications folder to the Trash, then empty it. For some complex apps, use their own built in uninstaller if provided in the folder.

While you are cleaning up, review browser extensions. Disable or remove anything you do not actively use, since heavy extensions can slow browsing and even affect the rest of the system when many tabs are open.

Adjust visual effects and animations

Modern operating systems add transparency, animations and visual effects that look nice but cost performance, especially on older hardware or integrated graphics.

On Windows, right clickThis PC, chooseProperties, then openAdvanced system settings. Under Performance, clickSettingsand selectAdjust for best performanceor customize by disabling animations and shadows while keeping smoother fonts.

On macOS, go toSystem Settings > Accessibility > Display. Turn onReduce motionandReduce transparency. This can make older Macs feel more responsive, especially when switching spaces or opening Mission Control.

Keep the system and drivers updated

Updates sometimes get a bad reputation, but many include performance fixes, security patches and improved drivers, which all help stability and speed in the long run.

On Windows, go toSettings > Windows Updateand install important and recommended updates. Also open your device manufacturer’s support app or website to check for graphics and chipset driver updates, particularly if you use a dedicated GPU.

On macOS, openSystem Settings > General > Software Updateand install available updates. If you are very low on storage, free space first, since macOS upgrades need significant room to download and apply.

Scan for malware and resource hogs

Malware and unwanted software can cause constant high CPU or disk usage. Running a reputable security scan is a good idea whenever your computer suddenly becomes slower with no clear reason.

On Windows, useWindows Security(built in) for a full scan, and consider a secondary on demand scanner from a well known security vendor for a second opinion. Avoid random “speed booster” tools, as many add problems instead of fixing them.

On macOS, unusual pop ups, browser redirects or unknown background processes can be a sign of adware or other unwanted tools. Remove suspicious apps from Applications, check browser extensions, and if needed, use a respected macOS security scanner to clean up.

Tweak browser habits for better responsiveness

For many people, the browser is the heaviest app on the system. A few small habits can prevent it from dragging everything down.

• Limit the number of open tabs, especially heavy web apps or streaming sites.
• Use a tab suspender extension from a trusted developer to pause inactive tabs.
• Clear cached data occasionally from the browser settings if pages feel sluggish.
• Avoid running multiple browsers at once unless you really need to.

When it might be time to consider hardware upgrades

If you have tried these software fixes and your laptop or PC is still slow doing basic tasks, the limiting factor may be the hardware. Very old hard drives, 4 GB of RAM or aging low power processors can only go so far.

For many systems, two changes bring the biggest jump in performance: upgrading from a hard drive to a solid state drive (SSD) and increasing memory to at least 8 GB. If you are not comfortable opening the device, a local repair shop can usually advise on what is possible and worth the cost.

Even without new parts, applying the steps above often turns a frustrating machine back into something that feels usable for web browsing, writing and light media work.
