How do I uninstall Picasa?

You can uninstall Picasa from either the Windows Add/Remove Programs control panel or by using the Uninstall option within the Picasa 3 Program group ("Start" > "Programs" > "Picasa 3" > "Uninstall").
During the uninstall process, you will be prompted to remove the Picasa database as well. Select "Yes" if you want to erase any organization or edits you've made in Picasa (if you have no intention of reinstalling Picasa). Click "No" if you want to retain any edits you've made (if you intend to reinstall Picasa).
After you uninstall, there may be residual files or folders from the Picasa installation. You can remove the Picasa folder by doing the following:
1. Open "My Computer" > C: drive > 'Program Files.' > 'Google.'
2. Right-click the Picasa 3 folder.
3. Click "Delete."
4. Click "Yes."
Picasa 3 will now be completely removed from your computer.
