You can often make Windows feel more responsive without upgrading hardware or overclocking by addressing the cause of the slowdown: unnecessary startup activity, low storage, outdated software, malware, visual effects or a power setting that favors battery life. These six built-in Windows fixes are worth trying, but none guarantees a speed increase; Microsoft notes that older hardware may not improve significantly. Start by checking Task Manager for clues, then make targeted changes and see whether the specific problem improves.
What should I check before changing Windows settings?
First, identify what feels slow: startup, opening apps, switching between windows or performance while the PC is idle. A fix is more useful when it addresses the bottleneck. Open Task Manager with Ctrl + Shift + Esc and look at CPU, memory and disk activity. The readings can help you notice which resource is busy while the slowdown happens; they do not, by themselves, prove what caused it.
Microsoft’s guidance lists several possible causes, including limited storage, too many apps running in the background, outdated software and hardware that no longer meets modern needs. If the PC is slow only during one particular task, a general Windows setting may not help that task. Make one or two changes at a time and check whether the original symptom changes. That makes it easier to undo a change that is unhelpful.

How can I make Windows faster without upgrading hardware?
Try these six fixes in the order that best matches your symptoms. Start with updates and a malware scan, then address storage and background activity. Treat visual effects, power mode and drive optimization as targeted adjustments rather than universal speed boosts.
1. Install Windows updates and relevant drivers
Go to Settings > Windows Update, check for updates and install those offered for your PC. Then review Advanced options > Optional updates for relevant driver updates, if that section is available. Restart when Windows asks you to.
Updates are a sensible maintenance baseline: Microsoft says they often include fixes and performance improvements. That does not mean every update will make a particular computer faster. For a driver, choose an update that applies to the device in question; do not install unrelated optional items just because they appear in the list.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
2. Scan for malware
Open Windows Security > Virus & threat protection and run a scan. Malware can use processor or disk resources, so it is one possible cause of sluggish performance. If the scan finds a threat, follow Windows Security’s instructions to address it and then check whether the original symptom persists.
A clean scan is not a speed optimization in itself. If the PC was not infected, a scan should not be expected to improve performance. Keep security protections enabled; disabling them is not a safe shortcut to a faster computer.

3. Free storage and remove software you no longer use
When the system drive is crowded, Windows may have less room to work with. Open Settings > System > Storage > Storage Sense and run Storage Sense. Review temporary files before removing them, and uninstall applications you recognize and no longer need. The exact categories and controls shown can vary by Windows version.
Removing unused software can free storage and reduce some background activity, but the amount of space recovered depends on what is installed and selected. There is no universal free-space percentage or guaranteed amount of storage that will make every PC faster. Avoid deleting files simply because their names are unfamiliar, and check the contents of any cleanup category before confirming removal.

Apps that launch automatically can lengthen startup and continue using resources afterward. Press Ctrl + Shift + Esc to open Task Manager, select Startup apps, and disable applications you do not need to launch when you sign in. If the list does not show a name you recognize, find out what it is before changing its startup setting.
For apps that support Windows’ background permission control, go to Settings > Apps > Installed apps, select the app’s menu, choose Advanced options, then set Background app permissions to Never. This option is not available for every app. Do not disable security software, hardware utilities or synchronization tools blindly: you may rely on them for protection or device features.
These changes are targeted and reversible. If a needed app stops working as expected, return to the same control and re-enable its startup or background permission. Focus first on apps you recognize and do not need immediately after sign-in.

5. Reduce visual effects
Search Windows for Adjust the appearance and performance of Windows and open Performance Options. Choose Adjust for best performance to turn off visual effects, or keep the current selection and selectively disable effects such as animations or transparency.
Windows’ visual effects use system resources, so reducing them may help a resource-constrained PC feel more responsive. The difference may be more noticeable in the interface than in the speed of demanding applications. Turning off more effects also makes Windows look less polished. If the appearance is too plain, return to Performance Options and select individual effects rather than applying the broadest setting.
6. Choose a power mode and use Windows drive optimization appropriately
When a laptop is plugged in and responsiveness matters more than energy use, open Settings > System > Power & battery > Power mode and select Best performance, if available. Microsoft warns that this mode uses more power, can drain a laptop battery faster and may make the device run warmer. Switch back to a less demanding mode when battery life or heat matters more.
For routine drive maintenance, search for and open Defragment and Optimize Drives, then use the built-in interface to review or optimize a drive as Windows offers. Do not manually defragment drives indiscriminately or assume that optimization will produce a universal speed gain. Drive type and Windows’ available options matter, and the supported guidance does not establish one result for every PC.
Which fix should I try first?
Use the symptom to choose a starting point. You do not need to apply every setting if the evidence points to one narrow cause.

- Slow sign-in or startup: check Task Manager’s Startup apps list and disable only unnecessary launchers.
- Slowdown while idle: inspect CPU, memory and disk activity in Task Manager, then consider whether an unnecessary background app or malware scan is relevant.
- System drive nearly full: review Storage Sense and remove temporary files or software you no longer use.
- Interface feels sluggish on a resource-constrained PC: try reducing visual effects and decide whether the simpler appearance is an acceptable trade-off.
- Need responsiveness while plugged in: consider Best performance mode, keeping its battery and heat costs in mind.
A practical sequence is to reproduce the slowdown and check Task Manager, install Windows updates, run a malware scan, clean up storage, reduce unnecessary startup and background activity, then try visual effects or power mode if they fit the symptom. Use Windows’ drive-optimization tool where appropriate. If a change does not help, reverse it rather than stacking more changes without a reason.
What should I avoid when trying to speed up Windows?
Prefer specific, reversible settings over broad changes that are difficult to understand or undo. Windows already includes tools for updates, security scanning, storage cleanup, startup management and drive optimization; start there before adding another utility.
- Do not turn off Windows Update or Microsoft Defender to chase performance. Updates and security protection address maintenance and safety needs, and disabling them is not a supported performance fix here.
- Do not disable random Windows services or use blanket “debloat” scripts. The recommended changes are targeted controls, not instructions to remove system components.
- Do not make registry changes based on a generic speed-up list. The documented steps do not establish that registry hacks will improve your PC.
- Do not expect third-party repair software to be necessary. If considering any extra utility, assess its claims, privacy implications and trustworthiness; Windows has native options for the tasks covered here.
- Do not expect software changes to overcome every hardware limit. Microsoft says older hardware may not improve significantly from these steps.
Do these steps apply to Windows 10 as well as Windows 11?
The settings and tools described are Windows features, but exact paths, labels and available options can vary across versions and devices. Most importantly, performance tweaks do not extend an operating system’s support period.
Microsoft states that free Windows 10 software updates, technical assistance and security fixes ended after October 14, 2025. That date has passed. If you are still using Windows 10, these maintenance steps do not replace the need to consider a supported operating system. Check Microsoft’s current Windows support information for the implications for your edition and circumstances.
What can these fixes realistically change?
They can address software-side causes of sluggishness when the problem is related to storage, startup activity, background apps, malware or settings. The expected benefit depends on which cause applies. For example, disabling an unnecessary startup app is most relevant to startup and background activity; it is not evidence that a demanding application will run faster.

Microsoft describes these steps as things that may help and recommends trying multiple solutions because several factors can contribute to slow performance. Its guidance does not provide a universal percentage improvement or a guaranteed time saved. If the same task remains slow after relevant software causes have been addressed, the remaining limitation may be outside the scope of these settings.
Frequently Asked Questions
Can these Windows changes improve gaming FPS?
The guidance for these fixes does not establish a measured FPS increase. Startup or background activity could be relevant if it is competing for resources, but the result depends on the cause of the slowdown and the game.
Why is Best performance missing from Power mode?
The option may not be available on every device or Windows configuration. If it is absent, use the power modes Windows does offer rather than changing hidden settings to force it.
Should I buy a PC cleanup or optimizer app instead?
Not as a first step: Windows includes tools for the cleanup and maintenance tasks covered here. Any additional utility introduces a separate trust and privacy decision, and a speed claim should not be treated as a guaranteed result.
