Ensure that your antivirus software is up to date with the latest virus definitions to effectively identify and eliminate any potential threats. Consider scheduling regular scans to run automatically in the background to proactively safeguard your system against malware and viruses. In addition to antivirus scans, it’s also recommended to perform periodic full system scans with dedicated anti-malware tools to ensure comprehensive protection against different types of threats that could be impacting your system’s RAM usage.

Taking proactive steps to maintain a secure and malware-free system not only improves overall system performance but also helps in mitigating high RAM usage issues caused by malicious software. By implementing regular scans and staying vigilant against potential threats, you can ensure a smoother and more efficient computing experience while minimizing the risk of encountering RAM-related performance issues.

Increase Virtual Memory Allocation

Increasing virtual memory allocation can help address high RAM usage caused by the Desktop Windows Manager. Virtual memory is essentially a portion of your hard drive that the operating system designates to act as additional RAM when actual physical RAM is running low. By increasing the virtual memory allocation, you are providing your system with more space to store temporary data when the physical RAM is maxed out, which can help prevent performance issues caused by high RAM usage.

To increase virtual memory allocation on your Windows system, you can access the System Properties settings and navigate to the Advanced tab. From there, click on the “Settings” button under the Performance section, then go to the Advanced tab again and click on the “Change” button under Virtual Memory. Here, you can adjust the initial and maximum size of the virtual memory based on your system requirements and available hard drive space.

By tweaking the virtual memory settings and allocating more space for system performance, you can effectively manage high RAM usage due to Desktop Windows Manager processes. It is important to strike a balance between the virtual memory allocation and physical RAM capacity to ensure optimal system performance and prevent any potential issues arising from excessive memory usage.

Consider Upgrading Your Hardware

If you find that your Desktop Windows Manager high RAM usage persists even after trying various software fixes, it might be time to consider upgrading your hardware. Upgrading your RAM can significantly improve your system’s performance and help reduce the strain on your computer’s resources.

Additionally, upgrading your CPU or switching to a solid-state drive (SSD) can also provide a boost in performance and help alleviate high RAM usage issues. Investing in newer hardware can not only enhance your overall computing experience but also ensure that your system can handle the demands of modern applications and software.

While hardware upgrades may require a financial investment, they can prolong the lifespan of your computer and prevent slowdowns caused by high RAM usage.
