“MemoryCleaner” can refer to different apps. These steps cover Igor Mundstein’s Windows Memory Cleaner (WinMemoryCleaner); confirm the publisher and app before proceeding. Start with automation off, verify the download, and run a manual optimization only after you understand which memory operation you’re selecting.
Confirm the app and download it from an official route
The project describes WinMemoryCleaner as a free, portable Windows application. Its official website links to the project repository and lists installation routes through Chocolatey, Scoop, and WinGet. The official repository contains the app’s settings and operating instructions.
Before following this guide, check that the application you have is Igor Mundstein’s WinMemoryCleaner. A similarly named program from another publisher may have different settings and requirements.
Verify the executable before running it
- Obtain the app from the official project repository or use an installation route linked from the official website.
- Before launching a downloaded executable, open its Properties and inspect the Digital Signatures tab. Check the signer and timestamp as the project instructs.
- If the release notes publish a SHA-256 value for your specific release, compare the file’s hash with that value. Do not assume a hash exists for every release or that a general hash applies to your file.
- If you plan to replace an existing executable, export the settings first using the backup steps below. Keep a copy of the previous executable until the replacement works.
These checks can help you assess a file, but they do not independently establish that any particular copy is authentic. If Windows, SmartScreen, or antivirus software warns about a file, do not bypass the warning solely because the project says some detections can be false positives.

Start with manual optimization, not automation
WinMemoryCleaner requires administrator privileges. Its settings include automatic optimization on a timer or when free physical RAM falls below a configured percentage, as well as run-on-startup, a hotkey, tray notifications, a process-exclusion list, and low-priority mode. Automatic and startup options can cause the app to act without you opening its main window.
A cautious first setup is to leave automatic optimization and run-on-startup off. Run an intended operation manually, then observe your PC’s behavior. This staged approach is practical caution, not a workflow specifically prescribed by the project.

What the automation controls do
- Every X hours: triggers optimization at the selected interval.
- Free physical RAM threshold: triggers optimization when free physical memory drops below the selected percentage.
- Run on startup: adds startup integration; the project says this creates a scheduled task.
- Optimization hotkey: lets a keyboard shortcut trigger an operation.
- Process exclusions: lets you exclude processes from the operation where appropriate. Consider applications that are sensitive to interruptions.
- Low-priority mode: lowers the app’s own process priority; optimization may take longer.
- Tray notifications: controls notifications from the tray.
If you later enable automatic optimization
- Choose either a time interval or a free-memory threshold and understand what that trigger means for your use.
- Set the interval or percentage deliberately; do not treat a low-free-memory trigger as proof that a cleanup is needed.
- Use the process-exclusion list for applications you do not want affected, where appropriate.
- Keep track of how the operation was triggered and how to turn it off in the app’s settings. Disable automation if you notice unwanted behavior.
Choose an operation by its target, not by the promise of more free RAM
The project documents several distinct operations. They target different memory areas, and some have Windows-version requirements. Read the operation’s description in the app before selecting it; the table summarizes the project’s descriptions, not independent performance testing.
| Operation | Target or effect described by the project | Consideration |
|---|---|---|
| Standby List | Clears the entire standby list. | The project describes this as the more aggressive standby-list operation. |
| Standby List (low priority) | Clears only the lowest-priority standby pages. | The project describes this as the gentler standby-list choice. |
| Working Set | Removes memory from user-mode and system working sets. | Targets working sets rather than the standby list. |
| Modified Page List | Writes unsaved pages to disk and moves saved pages to the standby list. | Targets modified pages and changes their location or status. |
| System File Cache / Modified File Cache | Targets file caches; the project gives different descriptions for these operations. | Check the individual description in the app rather than treating the two as identical. |
| Registry Cache | A separate cache operation. | Check the project documentation for its stated minimum Windows version. |
| Combined Page List | A separate page-list operation. | Check the project documentation for its stated minimum Windows version. |
The project’s documentation gives minimum Windows versions for some operations, but the available descriptions do not establish the requirements for every operation in a compact comparable list. Check the repository’s current operation descriptions for the exact requirement before relying on an option: WinMemoryCleaner repository.

More free memory after an operation does not by itself mean that Windows or an application will run faster. The project materials describe features and intended targets, not independent tests showing a performance improvement on a particular PC.
Use administrator rights carefully
The project requires administrator privileges and specifically states: “You must run these headless operations with administrator privileges.” Grant elevated access only to a copy you have obtained and checked as carefully as you can; elevation increases what the application can do on the system.

Back up settings before replacing the app
The project says settings are stored under ComputerHKEY_LOCAL_MACHINESoftwareWinMemoryCleaner. Before replacing the executable, open an elevated Command Prompt and export the settings:
reg export "HKLMSoftwareWinMemoryCleaner" WinMemoryCleaner-reg-backup.regThe project’s advanced replacement guidance also says to stop the running instance, retain a backup, and check Event Viewer afterward. Exporting the registry creates a backup file; store it somewhere you can find before making changes.

Respond to warnings without weakening protection by default
The project attributes some antivirus or SmartScreen warnings to administrator privileges and the scheduled task created by startup integration. That is the publisher’s explanation, not proof that a particular warning is harmless. Verify the file and signer, and investigate a warning rather than automatically allowing the file.
The project mentions antivirus exclusions as a possible workaround, but an exclusion reduces protection. Do not make one a default setup step; use it only if you understand the risk and have resolved why the specific file is being flagged.
Reset a stuck configuration and find application events
Restore the documented defaults
The project says running the executable with /Reset restores factory defaults and closes stuck windows. The reset preserves the language choice and turns auto-update off. If you want updates, turn auto-update back on afterward.
Check the application log
To look for application events, open Event Viewer and go to Windows Logs > Application. The project identifies the source name as Windows Memory Cleaner.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesUse Windows tools to inspect memory behavior
The project points to Windows Resource Monitor for observing memory and names Microsoft Sysinternals Process Explorer and RAMMap as complementary diagnostics for process memory use and physical-memory allocation and caches. The project repository is the supplied source for these tool references; use its links to locate the relevant Microsoft tools.
