Windows 10: Issues updating Windows 10 1909 to Windows 10 21H1

My computer runs Windows 10 1909. I have tried to update it ever since 2004 came out. First, I tried through the Settings app, and it failed. It left the error code 0xc1900101. Next, I downloaded the Windows 10 Update Assistant, and it also did not work. Then I downloaded the Installation media from the website, and it gave me another error code, which I cannot remember, and a message saying how it failed to boot into safe mode. I have another PC which was able to update all the way to 21H1, so I am very puzzled. Note that I recently migrated the OS from my hard drive to SSD.

New install Windows 10 (issue solved)

It's good that you're not experiencing any issues. Unfortunately many folks are, a quick Google search will show the same info im offering the OP.

Heres a couple examples:

It's basically what I mentioned above, small issues here and there ,but nothing to end your day.. for the most part.

I know it's anecdotal, but for my experience 95% of the time it's perfectly fine. The issues I've run into wouldn't be enough for me to roll back , but they would be enough (had I not installed it yet) ,to avoid it for another couple weeks which is why I'm suggesting it to the OP

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
