Disable automatically enabling Windows Update Medic Service
Overview
This script improves your privacy on Windows.
These changes use Windows system commands to update your settings.
This script disables the upfc.exe
process, preventing it from automatically re-enabling Windows updates 5.
upfc.exe
is found at %SYSTEMROOT%\System32\upfc.exe
1 2.
This executable is identified by Microsoft as "Updateability From SCM" 1 2.
SCM refers to the "Service Control Manager (SCM)", a special system process also known as services.exe
3.
upfc.exe
is automatically launched by SCM during system startup 4.
It is part of the Windows Update self-healing mechanism 1.
It recovers Windows Update Medic Service (WaaSMedicSvc
) once disabled 1 5.
upfc.exe
operates early in the boot process and performs several functions 1:
- It checks the details of the
WaaSMedicSvc
against a configuration file, ensuring the service's settings match those listed 1. - If discrepancies are found, such as invalid registry settings,
upfc.exe
recreates the service according to the XML configuration file 1.
However, upfc.exe
also sends data about its operations to Microsoft 1 5, including details about discrepancies found and any corrective
actions taken 1 5. This data is part of the telemetry Microsoft collects 1, which raises privacy concerns.
This script will skip some of its disabling logic on older Windows versions due to community reports of disabling this service causing BSOD (blue screen of death) 5 6.
By disabling upfc.exe
, this script enhances user privacy by stopping the automatic sending of operational data to Microsoft.
However, it's important to note that this might impact the integrity and security of the Windows Update process. Users should weigh the
privacy benefits against potential security risks before using this script.
This script uses Batch (batchfile) scripting language.
This script is only recommended if you understand its implications. Some non-critical or features may no longer function correctly after running this script.
