What changes

Microsoft Compatibility Appraiser is a Windows process that collects data about the computer and the installed software in order to identify compatibility issues with future versions of Windows. According to the visible BoosterX description, the task scans the hardware configuration, installed drivers and installed programs; Microsoft analyzes this data, identifying possible issues when upgrading to a new version of Windows. The process starts periodically as part of servicing and the Windows Update service. Disabling it stops the scan and prevents unwanted background use of the processor and the internet.

Exceptions and differences

Trade-off: without Appraiser data, the assessment of the PC’s readiness for a major update becomes slower and less complete. Related collection mechanisms are disabled separately: Inventory Collector (system inventory) and CEIP tasks (Customer Experience Improvement Program). A one-time spike in load from the scan does not mean a permanent CPU reduction after disabling.

How to verify the result

Open “Settings” → “Windows Update” (in Windows 10 — “Update & Security” → “Windows Update”) and run a check for updates: it completes normally, without errors.

How to change and revert

Open “Optimization” → “Privacy” → “Scheduler and background tasks” → “Microsoft Compatibility Appraiser task”, set the toggle to “Enabled”: BoosterX will apply the disabling of the compatibility assessment task. Click “Apply”. With “Instant apply” enabled, a separate button is not required. To revert, set the toggle to “Disabled” and apply the change again: BoosterX will return Windows to its default state with the assessment task running.

Confirmation

• Inventory Collector and CEIP tasks — related collection mechanisms.
• Study of retention, search and delivery policies.
• The purpose of the task and the scope of the scan are described according to the visible BoosterX description; no public Microsoft documentation about the Microsoft Compatibility Appraiser task was found as of the verification date, so the statement remains without an external source.
