Critical Notes Before Reinstalling Your OS

1. Comprehensive Data Backup***

  • The installation process involves disk partitioning or formatting, which will result in the permanent deletion of all data on the target drive (typically Drive C).

  • Personal File Migration: Beyond standard "Desktop" and "Documents" folders, ensure you have backed up "Downloads," "Pictures," and any local save paths generated by third-party applications.

  • Communication & Collaboration Records: Verify that chat histories and file caches from IM tools (e.g., WeChat, Slack, Teams) have been migrated or backed up via their respective built-in utilities.

  • Browser Data: We recommend synchronizing bookmarks, saved passwords, and extension configurations via your browser account or manually exporting the configuration files.

2. Software Licensing and Identity Management

  • To prevent authorization conflicts or activation failures post-installation, please address the following:

  • Professional Software Licenses: For software tied to hardware or system IDs (e.g., Adobe Creative Cloud, CAD, or specialized scientific research tools), ensure you perform a "Deactivate" or "Sign Out" operation before reinstallation.

  • Multi-Factor Authentication (MFA): Ensure you have an alternative method of identity verification available, in case the reinstalled system restricts access to localized authenticator apps.

3. System Configuration and Credential Preservation

  • Software Environment Inventory: Compile a list of essential professional software and their specific versions to ensure consistency in your workflow after the update.

  • Account Credentials: Confirm and record the login credentials for any cloud accounts associated with the operating system (e.g., Microsoft Account, Apple ID).

4. Other

  • Peripheral Management: We recommend disconnecting unnecessary external storage devices before starting the installation to mitigate the risk of accidental data overwriting.
