Task Manager Shows CPU Usage at -1%

I noticed something strange on my Windows PC when I opened Task Manager and checked the performance tab, because the CPU usage was showing -1% instead of a normal percentage. At first, I thought it might be a temporary display glitch, but the unusual reading made me wonder whether something was wrong with Windows, the performance counters, or a background process. Has anyone experienced this issue before, and what troubleshooting steps can help identify the cause and restore accurate CPU usage readings?
