Release channel: Experimental Building on the work we've been doing to improve the context menu experience:

• In theme with giving you more control, you can also now turn off the customize context menu entry in the new context menu settings.
• We've fixed a few small issues with the Send To option in the context menu not working as expected.

[File Explorer search]​

• Search from This PC in File Explorer is now indexer-based, making it much faster and consistent with search from File Explorer Home.

Thanks, Stephen and the Windows Insider Program team
