Hello Windows Insiders!

Today, we are releasing Windows 10 Insider Preview Build 17758 (RS5) to Windows Insiders in the Fast ring.

What’s new in Storage Sense

Starting with Windows 10, Storage Sense has embarked on a path to keep your storage optimized. We’re making continuous improvements in every feature update. From Build 17720 and later, we’re adding a new capability and making a few changes to Storage Sense’s behavior. Storage Sense now has the capability to automatically free up disk space by making older, unused, locally available files be available online-only. Learn more in the Storage Sense blog post here.

General changes, improvements, and fixes for PC

The build watermark at the lower right-hand corner of the desktop is no longer present in this build. This does not mean this is the final build as we are not done yet . We’re just now beginning the phase of checking in final code to prepare for the final release.

We’re just now beginning the phase of checking in final code to prepare for the final release. We fixed an issue resulting in the back button in Settings and other apps becoming white text on a white background if you hovered over it.

We fixed an issue resulting in Narrator not reading selected word choices when typing using an IME (for example, in Japanese).

We fixed an issue resulting in certain apps crashing when you tried to save a file from the app.

We fixed an issue resulting in explorer.exe crashing recently when clicking on the “Import photos and videos” option from an autoplay notification.

We fixed an issue resulting in nearby sharing not working for local accounts where the account name contained certain Chinese, Japanese, or Korean characters.

[UPDATED] We fixed several bugs causing text clipping issues when you use “Make text bigger” setting in Ease of Access.

Known issues

Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.

[ADDED 9/12] Apps that use .NET 4.7.1 will not work correctly on this build. This issue is fixed in the next flight. As a workaround until then, you can change your app config to list 4.7.2 instead of 4.7.1 to correct the issue. Or you can change/add these registry keys:

Both X86/X64: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.7.1] X64 only:[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.7.1]
