Disable disk diagnostic user notifications

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables the "Microsoft-Windows-DiskDiagnosticResolver" scheduled task.

This task warns users about faults reported by hard disks that support S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) 1.

This task is disabled by default. However, it is automatically enabled by the Diagnostic Policy Service when a S.M.A.R.T. fault is detected 1.

It runs %SYSTEMROOT%\System32\DFDWiz.exe 1 2. This executable is known as "Windows Disk Diagnostic User Resolver" 1 2.

Disabling this task enhances privacy by preventing the collection and display of information about your hard disk's health and performance. This data, though primarily technical, may reveal insights into your disk usage patterns.

Disabling this task may improve system performance by reducing background activities. Citrix recommends disabling this service for system optimization 3.

Caution

Disabling these notifications may prevent users from being aware of potential disk issues.
