Windows 10: Correct username under C:\windows\Users path in windows 10?

After doing a custom install of windows 10, due to BSOD error loop, I am facing few newer issues.

Issue 1:
Username path in C:\Users\ got changed automatically from C:\Users\Raghav to C:\Users\ragha somehow on this new custom install of Windows 10 (version 20H2).
why we don't have a choice in deciding our own username under "C\Users" in Windows 10.
It's very absurd to take first 5 characters from email-Id and make that a username.
How to revert back to the old username ?

Issue 2:
All the folders like Desktop, Documents, pictures have moved inside OneDrive, automatically.
Can't we customize which folder we want to keep in OneDrive?
How to move out these folder out of them, keep only those which we need to backup?


There must be some solution to these above issues in windows 10.

OS config :
Windows version 20H2(OS build 19042.508).

Equivalent of "c:\Users\username"

Vijay_Verma and DaveM21, thanks. I'll add that to my list of hints to remember,

Now, all I have to do is run the following command in PowerShell:

S C:\WINDOWS\system32> icacls "%userProfile%\Dropbox" /grant %USERNAME% (F) /T

When I try to run this command (which is taken from the Dropbox website), I get the following:

F : The term 'F' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

At line:1 char:51

+ icacls "%userProfile%\Dropbox" /grant %USERNAME% (F) /T

+ ~

+ CategoryInfo : ObjectNotFound: (F:String) [], CommandNotFoundException

+ FullyQualifiedErrorId : CommandNotFoundException

How do I correct this? (And I have two silarcommand waiting in the wings.)

 

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

Windows 10 Truncated username in C:\Windows\Users

In setting up a new PC, Windows 10 has truncated my username in C:\Windows\Users from the correct user name (e.g.
absmith) to absmi. Guru Kiran responded to this issue in a previous post, however his suggestions don't really work, or maybe just not in my case. To be clear, I do not need to change my
account user name -- that name is correct. I need to change the name in the
C:\Users folder.

I have several pieces of software that
must be installed in the absmith user folder. They will not install in my current user folder because the name is truncated to
absmi, so I am trying to rename the users folder to the correct name. Guru Kiran suggested renaming the user profile in the Registry, however that results in a new profile where everything previously set up is wiped out and I am back to square one,
or would be if I let it go that far. Complicating the issue are multiple connection and/or activation errors in Event Log, because many of the strings in the Registry have the correct user name, but even more have the wrong one.

I have been through every iteration of Windows since 3.1, and have never before encountered this problem until Windows 10 (1803).

My question is this: Is there any way at all that I can correct this mis-naming problem without have to go back to square one? I would not call myself a "power user", but I am comfortable editing the Registry and making other kinds of tweaks.
