Microsoft Shares How to Fix Windows 10 “c1900101” Boot Loop Issue (New Build Also Out)

Last night Microsoft released another Preview Build from the Windows 10 20H1 branch – the mega upgrade scheduled for a spring 2020 release. The latest Build is now available to Insiders in the Fast ring and brings some improvements and fixes.

However, this new build along with the last one has been causing some issues for a few Insiders who are receiving an error code c1900101 that is “due to a compatibility bug with a storage driver on their device,” according to Microsoft.

“The PC will attempt to install, fail, and successfully roll back to the currently installed build on the PC. Attempted re-tries to install the build, either manual or automatic, will not bypass this issue. A fix is forthcoming, but there are no known workarounds currently.”

Microsoft has promised a fix coming soon and added that, by default, the update will attempt to install 3 times. However, users can pause updates if they want to bypass the re-try attempts.

What to do if your Windows 10 PC gets stuck in a boot loop due to c1900101

Microsoft said in rare cases, devices could get stuck in a boot loop trying to re-install this build. If that happens, you need to follow these steps to get your machine back into a working condition:

1. Create a bootable USB recovery drive following these instructions. NOTE: UNCHECK “Back up my System files to the recovery drive”.
2. Boot your PC from the USB recovery drive created in Step 1.
3. Launch Command Prompt.
4. In Command Prompt, type: bcdedit /enum {default}
5. Text similar to below will appear:
6. If the description element says “Windows Rollback” and the device element starts from ramdisk, proceed to Step 7. If you don’t see any of the elements from Step 5 – DO NOT PROCEED.
7. Take a note of the recoverysequence GUID value in the {default} entry.
8. In Command Prompt, type: bcdedit /default {GUID from Step 7 exactly as it appeared}
9. In Command Prompt, reboot your PC by typing: wpeutil reboot
10. Once your PC reboots, you will see two boot entry choices the first one will be “Windows 10” and the next one will be “Windows Rollback”. Select the “Windows 10” option and that will enable to boot you back into the previously installed build.The rollback code will kick in and clean up the rollback entry, so it won’t be there on subsequent boots.

Remember, these are early builds of Windows 10 20H1, which is almost a year away. If you want to avoid these kind of problems, then you can switch to Slow ring that is currently testing Windows 10 19H2, due to release in October as a cumulative update.

Here’s the complete changelog of Windows 10 2020 Preview Build 18941:

Updating the Korean IME

Earlier in this development cycle, we released updated versions of both the Chinese and Japanese IMEs. As part of our ongoing efforts to modernize and improve your typing experience in Windows, today we’re rolling out an updated version of the Korean IME to all Insiders in the Fast ring. This update is going out with the goal of making the IME more secure, reliable, and more beautiful to look at.

For those who’re familiar with typing in Korean, the changes will be most noticeable if you write in Hanja; we have a new candidate selection window that uses modern controls and clearer typography:

We have also improved the algorithm used for text prediction when writing Korean using the touch keyboard. Text suggestions should now be more accurate and relevant to what you are writing.

With this change, we have a couple of known issues we’re working on addressing:

• Typing very fast in Notepad can cause the IME to stop working. If you experience this, restarting Notepad should resolve it.
• Pressing hotkeys, such as CTRL + A, in while in the middle of writing a Hangul letter has inconsistent behavior across apps.

We started rolling this change out to a small portion of Insiders a few days ago, and appreciate the feedback shared so far! Your feedback helps make Windows is better for everyone, so please don’t hesitate to continue sharing your thoughts and experiences.

General changes, improvements, and fixes for PC

• We fixed an issue resulting in some users experiencing a large amount of lag when using the previous flight.
• We fixed an issue where explorer.exe would crash if you started a File Explorer search while in a OneDrive folder.
• We fixed an issue where if you searched for advanced Windows Update options, the search result would open to the main Windows Update Settings page, rather than the advanced one.
• We fixed an issue where Settings would crash if you clicked on the microphone section under Privacy Settings while audio recording was in progress by a Win32 application.
