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.
