Users sometimes "patch" modern drivers to work on older operating systems like Windows XP or 7 when official support has ended.
The hardware string identifies the Intel 8 Series/C220 Series Chipset Family SMBus Controller . This vital motherboard subsystem manages vital hardware monitoring, such as temperature tracking, fan speeds, and power configurations. When a user searches for this string appended with "patched" , they are typically resolving an exclamation mark error in Windows Device Manager, trying to slipstream drivers for legacy setups, or deploying modded INF configuration files to force compatibility on unsupported operating systems.
Given this breakdown, the string seems to describe a piece of hardware (likely a graphics card, network card, or another peripheral) made by Intel (VID 8086), with a specific device ID (8c22), and additional subsystem and revision information. The fact that it's "patched" suggests some form of update or fix has been applied to the device.
