I tested Microsoft PC Manager’s RAM-freeing tool and learned why high memory usage isn’t always a problem

In the realm of Windows 11, users frequently express their concerns regarding elevated memory usage as they glance at Task Manager. It’s not unusual to observe RAM utilization hovering around 70, 80, or even 90 percent. Such figures often trigger assumptions about system slowdowns, excessive resource consumption by the operating system, or the pressing need for a memory upgrade. To alleviate these worries, Microsoft has introduced the PC Manager, an application featuring a one-click “Boost” option that claims to liberate memory and enhance performance instantly. However, before hastily clearing memory at the sight of high percentages, it’s crucial to comprehend the underlying processes at play.

Why Windows 11 uses so much memory

Understanding the distinction between “good” memory usage and “bad” bloat is essential. When Windows 11 utilizes RAM to cache files, it can promptly relinquish that memory when another application requires it. Conversely, if a single application or browser tab consumes several gigabytes due to poor optimization or a memory leak, that indeed signals a legitimate resource issue, warranting the closure of the app or the use of tools like PC Manager. Various factors can influence system performance, including the type and speed of the local drive, available disk space, thermal throttling, processor limitations, and the number of startup apps and background processes. If your computer remains responsive during your typical workload, high memory usage alone is generally not a cause for concern.

So how much RAM usage is too much?

There isn’t a universal threshold applicable to all computers. For some users, a memory usage of 90 percent may be entirely normal, especially when juggling numerous browser tabs, editing images, or managing virtual machines. Personally, I find myself in this category; with a system boasting 96GB of RAM, I’ve yet to experience any slowdown in my applications, even when memory usage exceeds 90 percent.

However, context is paramount. On an 8GB system operating at around 85 percent memory usage, the available capacity for additional tasks is severely limited. At this juncture, Windows 11 must rely more on memory compression and offload data to the storage drive, potentially resulting in noticeable slowdowns or stuttering. High memory usage on a high-end machine often signifies normal caching, whereas on a lower-end system, it may indicate that the hardware is beginning to struggle. My guiding principle is straightforward: if memory usage consistently hovers between 85-90 percent and performance issues arise, it may be time to consider a RAM upgrade. Conversely, if performance remains smooth, Windows 11 is likely managing memory as intended.

Windows Central’s Take

Whenever I come across a screenshot showcasing 85 or 90 percent memory usage on Windows 11, the immediate reaction often suggests, “You need more RAM.” However, this is frequently a misconception. My experiments with Windows 11 across systems with 8GB, 16GB, and 32GB of memory have revealed that the operating system will efficiently utilize available RAM to enhance performance. This behavior aligns with the design of modern operating systems—unused memory does not equate to a faster computer.

This brings us to the dual nature of Microsoft PC Manager’s Boost feature. While it serves as a handy tool for swiftly freeing resources on low-memory systems or when an application misbehaves, it may inadvertently reinforce the notion that high memory usage is inherently negative, which is not the case. The sole significant exception arises just before launching a resource-intensive task. If you’re about to dive into a demanding game or commence rendering a 4K video, activating the “Boost” feature beforehand can be beneficial. It clears background tasks early, ensuring that your heavy application has immediate access to memory without waiting for the system to reallocate resources.

When you check Task Manager and see memory usage at 80 or even 90 percent, resist the urge to rush into a memory upgrade. Instead, consider a more pertinent question: Is your device actually slow? If applications launch quickly and multitasking remains fluid, Windows 11 is likely managing memory effectively. For me, the true indicator that it’s time for additional RAM isn’t merely a percentage displayed in Task Manager; it’s when I begin to notice slowdowns, app reloads, stuttering, or other performance hiccups during my regular workflow. That’s when the addition of memory truly makes a difference.
