Here's what's fixed, improved, and still broken in Windows 10 for PCs build 14955

Microsoft released this week's Fast ring build today, which is Windows 10 build 14955 for PCs and phones. The build contains a couple new features, but they're all pretty minor.

We'll likely hear more about upcoming major new features at tomorrow's event, which is to be held in New York City. The company is also rumored to be revealing a new Surface all-in-one PC, which could be called Surface Studio.

While today's build didn't offer much in terms of features, it does have a long list of fixes and improvements, along with a couple known issues. Here are the fixes and improvements for the PC build:

• Now you can draw along the protractor and have the degree visual remain visible until you start drawing again. We’ve also updated the degree visual to be more clear – black text on a white background, as opposed to the previous black text on a red background.

• We fixed the issue causing you to be unable to sign into apps such as Feedback Hub, Groove, MSN News, etc. with your Microsoft Account if you sign out or get signed out of these apps.

• This build includes several fixes for precision touchpad:

  • We fixed an issue where precision touchpad was mis-classifying presses when mousing with one finger and pressing with another.

  • We fixed the issue in which “Reset touchpad” was appearing on PCs that don’t support precision touchpad (legacy touchpad).

  • We fixed the issue where the 4-Finger gesture graphic would be viewable in Settings on PCs that support only 3-contact.

  • We fixed an issue with popular graphics app Paint.NET where horizontal scrolling was broken.

• This build includes several fixes for Narrator:

  • We have added a new key command to read the active window title of the current application. You can use Caps Lock + / for this.

  • We’ve improved Narrator’s recognition of edit boxes on the web in Scan Mode so you get the message to use space to edit more consistently when focus has moved to an edit box.

  • We’ve done work to ensure that continuous reading is interrupted appropriately if focus changes or you issue a Narrator command that should stop continuous reading. We’ve also worked to ensure that continuous reading doesn’t stop when it shouldn’t.

• We’ve updated the Trusted Platform Module Management control panel (TPM.msc) to provide additional detail when the TPM is “Not ready for use” or “Ready for use, with reduced functionality”.

• We fixed an issue resulting in Task Manager always opening with the default view, despite having configured it on the previous launch (for example, to “Show more details”).

• We fixed an issue where attempting to partition a USB drive via DiskPart would fail with the error “The system cannot find the file specified”.

• We fixed an issue where certain USB drives were failing to mount automatically or via Device Manager, despite being mountable using Disk Management.

• We fixed an issue where Accessibility settings were failing to roam down-level to some PCs running the Windows 10 Anniversary Update – triggering a sync loop and possibly causing some performance issues on those down-level PCs. If you have encountered this issue, to get out of this state – you will need to change a setting under Settings > Ease of Access so that fix will roam down-level. Whichever setting you changed to trigger roaming can be changed back if needed.

• We fixed an issue where Settings would crash when copying hardware properties from the Wi-Fi settings page.

• We fixed an issue where files were no longer automatically selected after being pasted into a folder in File Explorer.

• We fixed an issue resulting in not being able to enter input into the Time or Place fields when creating a Reminder in Cortana.

• We’ve updated the advanced tab of the device properties window in the Sounds

• control panel to now allow you to select the following sample dates as the default format for devices that support it: 24 and 32 bit at 176400Hz, and 16, 24 and 32 bit at 352800 Hz.

• USB Audio 2.0 devices are now named based on the make/model of the device, rather than using a generic name, in places across the system, for example Device Manager.

• We fixed an issue in Microsoft Edge that prevented dragging content out of the browser to other windows

• We fixed an issue that caused Microsoft Edge to crash when using the Share button to share web pages and PDFs to Mail.

Here are the known issues:

• If you have a 3rd party antivirus product installed on your PC – your PC might not be able to complete the update to this build and roll-back to the previous build.

• Insiders may experience the Windows Ink Workspace crashing when using the protractor – we’re investigating.

The known issues shouldn't be very serious at this point. The issue with third-party antivirus software has been present in Development Branch builds for some time, so it should come as no surprise.

If you're on the Fast ring, you can grab today's new build by heading over to Settings -> Update & security -> Windows Update -> Check for updates. If you're not, go to the Windows Insider Program tab and click Get started. Once your PC reboots, go back and set it to the Fast ring.
