Windows has been around for over four decades now, and so have tips and tweaks promising instant performance gains. While some are helpful, most don't deliver any noticeable improvements. That's because many of the tweaks were designed for older versions of Windows, outdated hardware, or specific setups. In fact, applying these tweaks can do more harm than good. More often than not, they will introduce issues that negatively impact system performance and stability.

Windows has improved significantly over the years, not just in terms of UI, but also in how it handles key processes, background tasks, and resource allocation. As a result, much of the age-old advice floating around in forums and tutorials is no longer relevant. If you are an everyday user, leaving certain things to Windows might actually be the smarter choice.

Regularly updating the drivers

Aggressive updates are never a good idea

One of the biggest misconceptions is that updating drivers instantly boosts performance. And while that might be true for a few drivers, like the GPU or network adapter, updating others has little impact on performance. On the contrary, you might end up facing compatibility issues. Windows does a fairly good job at handling the process, shipping necessary drivers via Windows Update. It also ensures that only driver versions compatible with your system are installed. Using third-party tools or manually downloading drivers from unreliable sources often results in generic versions that are not optimized for your PC's hardware or Windows version.

You should only update drivers if the currently installed version has a bug or the latest version introduces new features, which is usually the case with GPU drivers. For all other drivers, relying on Windows Update is the safest approach.

Disabling services improves performance

It can trigger stability issues in the long run

Your Windows PC usually has over a hundred active services running in the background. Most of these are related to core Windows processes, and others pertain to third-party apps. While disabling a few, especially the resource-intensive ones, does sound appealing, it can introduce instability or cause features to stop working. For instance, disabling the Windows Update service can cause errors during update installation. Or turning off Windows Search will make file search significantly slower since Windows is no longer indexing files. Then, there are a few that don't seem critical but are interconnected with other services that are.

I agree, there are a few services you can safely disable on Windows. But if you have a fairly modern PC, the effects on performance won't be as huge as you might have expected. At best, you get a tiny boost in performance, not more. There are other, far more effective ways to speed up an old Windows computer.

Using performance-optimization apps

Most settings can be configured manually

Most performance optimizers or PC boosters claim to tweak hidden settings that can boost your system's speed. But none of these settings or features are hidden in the true sense. They are simply scattered across different built-in utilities. For instance, a performance-optimization app will clear Windows cache and temporary files, but you can do the same using Disk Cleanup. Some change the power settings, which are again accessible via the native Settings app.

Honestly, this is not the real problem. Many of these apps don't clearly explain the changes they are making. So, when problems arise, troubleshooting becomes a challenge. Often, uninstalling the app doesn't revert the changes it made. Some apps are even bundled with PUPs (Potentially Unwanted Programs) and adware. So, it's best to steer clear of third-party performance optimizers.

Increasing virtual memory

Windows dynamically adjusts it for performance and stability

Virtual memory, or the pagefile, is a portion of the storage drive reserved by Windows that extends RAM. So, when your system runs low on RAM, the OS automatically moves some of the unused data to the virtual memory, freeing up RAM. And increasing virtual memory did work on older versions of the OS. But on modern iterations, like Windows 11, the system is more than capable of dynamically adjusting the virtual memory (pagefile size) when needed, based on the workload, RAM, and free storage. This is the best setting for performance on modern PCs, and even the default configuration.

Manually increasing the virtual memory also has risks. For instance, if the memory requirements exceed the set pagefile size, apps (or the system) may crash. On small storage drives, this will reduce the available free space. Besides, if your PC has sufficient RAM, virtual memory doesn't play that big a role, and you should let Windows take care of it.

Entirely disabling visual effects

No visible gains on modern hardware

I, too, have often talked about disabling visual effects on Windows, but it's vital to understand that this works on older PCs. Modern hardware can easily handle these, with minimal impact on performance.

On the flip side, you will notice a less refined, toned-down Windows interface. Even the text becomes unclear, affecting readability. So, unless your PC has outdated, extremely basic hardware, you shouldn't turn off visual effects.

Letting Windows do its job isn't necessarily bad

Windows today is designed for performance and stability. So, tweaking certain different parts of it doesn't deliver the same results it did years ago. I am not saying you should go with the default setup. There are aspects that need reconfiguration or tweaking, like removing bloatware, disabling startup apps, or even adding a few smart accessories. But some things are best left to Windows.
