We have fixed the issue causing Widgets preferences (temperature units and pinned widgets) to unexpectedly get reset to default.Fixed an issue where the min / max / close button might not be visible in File Explorer when using a contrast theme.The Mount option when right clicking things like ISO files should now show an icon in the context menu.Fixed a few issues impacting explorer.exe reliability.Fixed an issue causing hangs and crashes in apps (like Excel) when attempting to print in the last couple flights.Updated the default duration captured by powercfg -sleepstudy from 3 to 7 days.Now it has the rate of 20 keys per second (for example, when holding down the delete key). We are rolling out a small tweak to improve the key repeat rate for the traditional touch keyboard layout, as well as the default touch keyboard layout, so it feels more responsive.To add it (once it’s available to you), make sure Tamil (India) is listed under Settings > Time & Language > Language & Region, and then click the “…” next to the language, select Language Options, and add it to the list of keyboards. It’s a popular keyboard for inputting Tamil characters, so if you speak this language, please try it out! This keyboard is currently rolling out to a subset of Insiders while we evaluate the quality. We’re adding the Tamil Anjal keyboard for the Tamil language.We’re trying out different experiences in File Explorer to show search results.If that doesn’t work, please file feedback in Feedback Hub. If you don’t see these features right away, please try rebooting. File Explorer tabs and navigation updates (which began rolling out to the Dev Channel with Build 25136) are now rolling out to everyone in the Dev Channel.This currently only works with Microsoft accounts today with AAD support coming later. Users can toggle this feature via Settings > Accounts > Windows backup > Remember my preferences > Language preferences. The spelling dictionary will now use a language-neutral word list and we are trying out syncing this across all devices that use the same Windows account.
