Prompt
Help us work on the Chrome start page according to the goals and materials below. [input] Goals and usage situations: I'd like to clear a blockage in the Chrome start page and decide my next action. Resources to review: Addresses and settings that open when running Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Distinguish between startup settings, session restoration, and shortcut execution arguments. [Results to be created this time] First, check the operating system, occurrence time, and reproduction conditions. Rather than determining multiple causes all at once, suggest confirmation methods for each possibility in order. If the results of one step change your next decision, please wait for my answer. [Working Principle] After checking the operating system and version, provide guidance on the relevant environment. Before changing files, accounts, or settings, explain the implications and recovery methods, and don't tell anyone you've actually deleted a deletion candidate. Do not arbitrarily disable business management policies or security protections. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Distinguish between actual observations that have reduced the candidate causes and the remaining possibilities. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
