How to Make a PC Run Better | Fix Slowdowns That Matter

A slow Windows PC often improves after you trim startup apps, free storage, install updates, scan for malware, and restart.

A long list of startup apps can make a perfectly capable PC feel old before you even open a program. For anyone working out how to make a PC run better, the useful first move is to find whether startup load, storage, memory, CPU use, or a bad process is causing the slowdown.

Windows 11 already includes the tools needed for that job. Start with reversible changes, check whether each one helps, and leave hardware upgrades until the evidence points there.

Make Your PC Run Better: Changes With The Biggest Payoff

A Windows PC usually responds most to four things: fewer programs loading at sign-in, enough free storage, current Windows and driver updates, and lower background resource use. Changing random registry settings or installing a bundle of “speed booster” apps is not a good first move.

1. Restart the PC, then open only the apps you need.
2. Press Ctrl + Shift + Esc to open Task Manager, then check Processes and Performance for sustained CPU, memory, or disk pressure.
3. Notice what is slow: booting, opening apps, browsing, gaming, file transfers, or everything at once.
4. Apply one matching change, then test again before changing something else.

If one app sits at the top of CPU, memory, or disk usage while the PC is sluggish, close that app first. When performance returns as soon as the process ends, you have narrowed the problem to software rather than the whole computer.

Cut Startup Load Before Chasing Bigger Fixes

Startup apps are one of the easiest slowdowns to remove because disabling them does not uninstall anything. Leave security software, touchpad tools, audio control software, and hardware utilities alone unless you know they are optional.

1. Open Start > Settings > Apps > Startup.
2. Turn off apps you do not need every time you sign in, such as game launchers, chat clients, or update helpers you prefer to open manually.
3. For more detail, open Task Manager with Ctrl + Shift + Esc, select Startup apps, and review the impact shown for each enabled item.

After the next sign-in, the disabled apps should stay closed until you launch them yourself. If boot time improves, keep the reduced startup list and re-enable only anything you discover you need.

Free Storage Without Guessing What To Delete

Low free space can make Windows less responsive and can interfere with updates. Use Windows storage controls before manually digging through system folders.

1. Open Start > Settings > System > Storage.
2. Select Storage Sense, then select Run Storage Sense now.
3. Go back to Storage, select Temporary files, review the categories, and select Remove files only for items you do not need.
4. Remove unused programs from Settings > Apps > Installed apps by opening the three-dot menu beside an app and selecting Uninstall.

When Windows finishes removing eligible files, the storage page reflects the new usage. Check Downloads and personal folders yourself before deleting them; automated storage tools should not replace a quick look at files you may still want.

What Should You Change First?

The first change should match the symptom you can actually see. This keeps you from stripping features out of Windows when one startup app, full drive, or runaway process is doing most of the damage.

Microsoft’s current Windows PC performance steps cover the same core areas: updates, malware scans, storage, startup apps, power mode, and resource monitoring.

Update Windows And Scan For Malware

Windows updates can include performance fixes and optional driver updates, while malware can consume CPU and disk resources in the background. These two checks are worth doing before assuming the PC needs new parts.

1. Open Start > Settings > Windows Update > Check for updates.
2. Install available updates, then open Advanced options > Optional updates to review available driver updates.
3. Restart if Windows asks. A fully updated system shows You’re up to date on the Windows Update page.

For a malware check, open Start > Settings > Privacy & security > Windows Security > Virus & threat protection, then select Quick scan. Windows Security reports the result when the scan finishes.

Windows 10 reached the end of free Microsoft support on October 14, 2025. A Windows 10 PC still runs, but moving to Windows 11 is the supported choice when the hardware qualifies.

When Does Hardware Become The Problem?

Hardware becomes the likely limit when the same resource stays saturated during your normal workload after software fixes are finished. Task Manager can show whether storage, memory, CPU, or graphics hardware is the pressure point.

On many laptops and compact PCs, the CPU, GPU, RAM, or storage may be fixed in place or difficult to replace. Check the model’s service manual before buying parts; if the limiting component is not replaceable, reduce the workload or consider replacing the PC.

For a PC that still boots Windows from a mechanical hard drive, an SSD removes the hard drive’s storage-latency limit and usually improves boot and app-load responsiveness. Extra RAM matters more when memory pressure rises during the programs you use, while a faster CPU or GPU matters only when those components are the measured limit.

Use Performance Settings Only When They Fit

Power mode and visual effects can make a PC feel more responsive, but neither one fixes a failing drive or a system that lacks enough memory. Use these settings when Task Manager does not point to a more obvious bottleneck.

On a Windows 11 PC that exposes the setting, open Start > Settings > System > Power & battery, then set Power mode to Best performance. The selected value stays visible in the dropdown. On a laptop, this uses more power and can increase heat; if the option is missing because a custom power plan is active, choose Balanced in Control Panel > System and Security > Power Options, then check the Settings page again.

For older hardware, search Start for Adjust the appearance and performance of Windows. Open it, select the Visual Effects tab, then choose Adjust for best performance. The selected radio button remains marked after you apply the change; if you dislike the plainer interface, return to the same panel and restore the previous choice.

Use This Sequence Before Spending Money

The most efficient approach is to make one reversible change at a time, check the result, and spend money only after Task Manager shows a hardware limit.

1. Restart the PC and test it with only your normal apps open.
2. Use Task Manager to identify sustained CPU, memory, or disk pressure.
3. Disable nonessential startup apps and sign in again.
4. Run Storage Sense, review temporary files, and uninstall software you no longer use.
5. Install Windows updates and optional driver updates, then run a Windows Security quick scan.
6. Try Best performance power mode or reduced visual effects if responsiveness is still the issue.
7. Upgrade storage, RAM, CPU, or GPU only when the matching resource is consistently the bottleneck in your workload.
