Serious Memory problem after Windows 11 24h2 update

It seems like you're encountering a significant memory issue post the Windows 11 24h2 update. Let's break down the information you provided and suggest some troubleshooting steps.

Overview of the Problem​

You've highlighted that your system is suffering from some form of memory leak, consuming all 32 GB of RAM within a short time after booting. Your use of the Memory Compression function appears to be a primary culprit, causing memory usage spikes without a clear single process to blame.

Screenshot Analysis​

• Resource Monitoring Screen: This shows the memory usage is at 99%, which indicates a critical shortage of available memory.
• Task Manager (Processes): Here, you might notice various applications consuming significant resources, particularly the Memory Compression process.
• RAMMap Tool: This is effective for digging deeper into memory allocation per process. Processes like MemCompression are often memory-intensive, especially if there are underlying issues.

Steps Taken​

You have already done considerable troubleshooting, including:

• Updating drivers and BIOS.
• Running antivirus and antimalware scans.
• Removing exposure profile from RAM.
• Updating SSD firmware.
• Performing a clean boot.
• Terminating processes.
• Attempting to enable/disable memory compression.

Suggestions for Further Troubleshooting​

• Check for Known Issues: Sometimes, specific updates can lead to widespread problems. Verify if there are any known issues with the 24h2 update on the https://learn.microsoft.com/en-us/windows/release-health/windows11-release-information page.
• Use Windows Memory Diagnostic: Run the built-in memory diagnostic tool to rule out any hardware-related issues.
• System Restore: If you recently updated, consider rolling back the update if it contains known issues that haven’t been resolved yet.
• Disable Memory Compression: Although you mentioned BSOD issues when toggling this, if you can trace the specific settings that cause this behavior, it might be worth investigating further with advanced options.
• Perform a Clean Installation: While a last resort, if the above steps yield no symptoms, a clean reinstallation might be necessary to restore stability.
• Feedback Hub: Use the Feedback Hub to report your issue directly to Microsoft for further support or recognition of the bug.

Conclusion​

Given the complexity of your setup and the recent update, this is likely a software/firmware issue rather than a hardware failure. Monitor your system closely and stay updated on patch notes from Microsoft regarding the 24h2 release.
