File backups get most of the attention before a reinstall, but software licenses and settings are the thing people forget until they're already reinstalling an app and hit a screen asking for a product key they can no longer find. A little gathering beforehand avoids losing access to software you've already paid for, or spending hours rebuilding a setup you'd customized over years.

Find and record your license keys first

Before wiping anything, track down the license keys or activation codes for paid software you'll want to reinstall. The most common places they hide:

Store what you find in one place — a password manager's secure notes feature works well for this and keeps license keys alongside the account logins you'll also need after reinstalling.

Export settings from software that supports it

Many programs let you export your configuration as a file, which saves significant setup time after reinstalling:

Don't forget browser extensions and their data

Extensions themselves reinstall easily from the browser's extension store, but any data or configuration inside an individual extension (saved templates, custom rules) is often local to that browser profile and won't transfer automatically unless the extension has its own account-based sync. Check any extension you rely on heavily for a built-in export or account-sync option before wiping.

A pre-reinstall checklist worth running through

The recurring theme is that license keys and custom settings live in more places than people expect — an old email, an account dashboard, a menu inside the software itself. Ten minutes spent gathering these before a reinstall is far cheaper than the time lost hunting for a lost key or rebuilding a configuration afterward.
