Windows 11 users who rely on Microsoft Phone Link for cross-device connectivity are facing severe system instability. The software feature consumes excessive RAM, creating a bottleneck that disrupts daily tasks and gaming sessions. This issue persists years after initial reports, forcing users to choose between convenience and performance.
Users report severe system instability and memory leaks
The problem stems from a recurring bug in the Phone Link cross-device service running on Windows 11. A background process enters an infinite loop, causing the application to consume memory at an unsustainable rate. Users report RAM usage spiking to 25-30GB during active gaming sessions, which overwhelms typical system configurations.
Microsoft has not officially confirmed the specific bug causing these memory leaks, but the pattern is consistent across user reports. Some individuals have experienced daily usage hitting 15-20GB since the issue was first reported in 2023. The infinite loop behavior leads to noticeable system slowdowns and high memory utilization that persists until the process is manually stopped.
Users currently have two primary workarounds to restore system stability while waiting for a potential fix. Disabling the Phone Link feature entirely stops the memory leak, though it removes cross-device functionality. Updating the software may also help, though Microsoft has not released a patch that definitively resolves the root cause of the infinite loop.
