If you want to see what is using RAM in Windows, start with Task Manager. For a deeper look at how physical memory is allocated, use Microsoft RAMMap; for process and loaded-file context, use Process Explorer; and to track changes over time, use Performance Monitor (PerfMon). If you specifically want a tray utility that also cleans memory, Mem Reduct is the closest alternative covered here—but cleaning memory is not the same as diagnosing a problem.
What MemoryCleaner does—and what it does not establish
Kilhonet describes Memory Cleaner version 2.0.0 as a no-install utility that cleans several areas of memory and can clean automatically according to settings. Its update history notes improvements to automatic memory-usage monitoring stability and fixes related to long-running timers and cleaning behavior on June 8, 2026. Its FAQ says automatic cleaning can be triggered by memory usage or time intervals. These features combine basic monitoring with cleanup; the cited information does not describe detailed allocation analysis or a history of memory use. See Memory Cleaner’s update history and FAQ.
Which alternative should you choose?
| What you need | Tool | Best fit |
|---|---|---|
| A quick view of current resource use | Task Manager | Built into Windows; shows resource consumption, including memory, and lets you manage running applications. |
| Details about physical-memory allocation | RAMMap | Shows categories such as process working sets, prioritized standby lists, physical pages, and file data held in RAM. Analysis tool, not a tray cleaner. |
| Process ownership and loaded-object context | Process Explorer | Shows process ownership and files, registry keys, DLLs, and other objects processes have open or loaded. |
| A logged view of memory behavior over time | Performance Monitor (PerfMon) | Graphs and records Windows counters, which can help reveal trends when investigating a suspected leak. |
| Tray monitoring with optional cleanup | Mem Reduct | Its publisher describes real-time tray monitoring, cache and standby-list cleanup, automatic thresholds, and Windows 7, 10, and 11 support. |
Use Task Manager for a quick first check
Task Manager is the simplest place to check current memory use without installing another utility. Microsoft describes it as a system monitor for resource consumption, including memory, as well as a way to manage running applications. It is useful for a snapshot and for spotting processes that appear to be using substantial resources; it does not provide RAMMap’s physical-allocation views or PerfMon’s logged history. Microsoft’s Task Manager overview.
Use RAMMap to understand where physical memory is allocated
RAMMap is the better choice when a headline memory figure does not answer your question. It breaks physical-memory use into categories that include process working sets, prioritized standby lists, physical pages, and file data cached in RAM. That additional context can help explain why memory appears occupied without identifying a single application as the cause.

Microsoft lists RAMMap for Windows Vista and later. The current version documented on its page is 1.63, published March 26, 2026. RAMMap’s author, Mark Russinovich, describes it as a way to understand Windows memory management, analyze application memory usage, and answer questions about RAM allocation. Download and read about RAMMap v1.63.
Use Process Explorer for process and object context
Process Explorer helps when you need to identify a process and learn more about what it has open or loaded. Microsoft says it can show files, registry keys, and other objects a process has open, its loaded DLLs, and process ownership. This context can help investigate a particular process, but the cited overview does not describe RAMMap-style analysis of physical pages. Pair the tools when you need both process details and a broader view of physical-memory allocation. Microsoft’s Process Explorer overview.

Use PerfMon to investigate a suspected leak over time
A single reading cannot show whether memory use is steadily increasing. Performance Monitor can graph and log counters so you can observe behavior over time. Microsoft’s leak guidance names Pool Nonpaged Bytes, Pool Paged Bytes, and Paging File % Usage as counters to watch. The point is to look for sustained trends, rather than treating one high reading as proof of a leak. Microsoft’s PerfMon memory-leak guidance.

Choose Mem Reduct only if cleanup is part of the goal
Mem Reduct is the closest match here if you want monitoring and an optional cleanup action in one utility. Its publisher describes real-time tray monitoring, cache and standby-list cleanup, automatic thresholds, and support for Windows 7, 10, and 11. Its recovery percentages and performance benefits are publisher claims, not independent test results. No independent head-to-head performance test against Memory Cleaner is established here. See the Mem Reduct publisher’s site.
Keep the distinction clear: monitoring tells you what memory use is doing; cleanup changes memory state. A before-and-after free-memory number does not by itself show that an application had a leak or that the computer will perform better. For a suspected leak, logged trends and targeted investigation are more informative than a one-time cleanup.

A practical way to investigate high RAM use
- Check the snapshot: Open Task Manager and look at memory use and the processes consuming resources.
- Inspect allocation: If the overall figure remains unclear, use RAMMap to examine physical-memory categories, including standby lists and cached file data.
- Investigate a process: Use Process Explorer when you need ownership or loaded-object details for a specific process.
- Track a pattern: If you suspect memory use is growing over time, log relevant PerfMon counters and observe whether the change is sustained.
- Separate diagnosis from cleanup: Use a cleaner only if you want its cleanup function; do not treat reclaimed memory alone as proof of a fix.
How to make sense of the readings
- High RAM use is not a diagnosis. It does not by itself identify a responsible process or prove a leak.
- Cached or standby memory needs context. RAMMap can show allocation categories that a simple total does not explain.
- A process view and a physical-allocation view answer different questions. Process Explorer supplies process and loaded-object context; RAMMap examines physical-memory allocation.
- Trends matter for leak investigation. PerfMon can record changes, but it cannot identify the source or independently establish the leak’s mode.
