I have tried all 3 methods several times now, yet the machine is still not running well. "Service Host: Local System (16)" is consistently sucking up 60% or more of the CPU. In addition, I cannot successfully run Windows Defender - when started it just continues running without completed an update.
Device Information:
HP Stream [2GB memory; 64-bit OS, x64 based processor: Intel Celeron N2840] running Windows 8.1
Microsoft Defender; no other security applications; several scans using Defender have been completed
Machine is up to date on Windows
Laptop is not running any applications
Please help!
