Access is denied. (os error 5) on re-installation of rustup using bleeding edge build

Verification

• I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue+is%3Aopen%2Cclosed and found no duplicates.
• I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

To resolve #4050, I was offered the 'bleeding edge build'. I was just using it for a re-installation and got this error:

info: rolling back changes
error: could not rename component file from 'C:\Users\my-user-id\.rustup\tmp\jkok1xr5cypspwh6_dir\rust-docs\share/doc/rust/html' to 'C:\Users\my-user-id\.rustup\toolchains\stable-x86_64-pc-windows-msvc\share/doc/rust/html': Access is denied. (os error 5)

after a series of messages (see below for full output) like this:

info: retrying renaming 'C:\Users\my-user-id\.rustup\tmp\jkok1xr5cypspwh6_dir\rust-docs\share/doc/rust/html' to 'C:\Users\my-user-id\.rustup\toolchains\stable-x86_64-pc-windows-msvc\share/doc/rust/html'

Steps

1. I downloaded the 'bleeding edge build' as mentioned in this comment on #4050, unpacking it to: C:\Users\my-user-id\Downloads\rustup-init-x86_64-pc-windows-msvc_bleeding_edge.
2. On my Windows laptop, I opened a PowerShell 5.1 tab in Windows Terminal Preview.
3. I set the proxy setting using $env:HTTPS_PROXY = 'blah.proxy-name.net:obscure-port'
4. I Installed Rust usingC:\Users\my-user-id\Downloads\rustup-init-x86_64-pc-windows-msvc_bleeding_edge, selecting option 1 "Proceed with standard installation (default - just press enter)" - I didn't save the output but some rety errors were shown.
5. I opened a new tab and closed the orignal to pick up the new PATH setting.
6. To isolate the particular change that allowed the installation to go ahead, I uninstalled it using rustup self uninstall. I did not notice any errors.
7. I opened a new tab and closed the previous tab to pick up the cleared PATH setting.
8. I set the proxy setting using $env:HTTPS_PROXY = 'blah.proxy-name.net:obscure-port'
9. I then reinstalled it using C:\Users\my-user-id\Downloads\rustup-init-x86_64-pc-windows-msvc_bleeding_edge. Full output below

	Welcome to Rust!

	This will download and install the official compiler for the Rust
	programming language, and its package manager, Cargo.

	Rustup metadata and toolchains will be installed into the Rustup
	home directory, located at:

	  C:\Users\my-user-id\.rustup

	This can be modified with the RUSTUP_HOME environment variable.

	The Cargo home directory is located at:

	  C:\Users\my-user-id\.cargo

	This can be modified with the CARGO_HOME environment variable.

	The cargo, rustc, rustup and other commands will be added to
	Cargo's bin directory, located at:

	  C:\Users\my-user-id\.cargo\bin

	This path will then be added to your PATH environment variable by
	modifying the HKEY_CURRENT_USER/Environment/PATH registry key.

	You can uninstall at any time with rustup self uninstall and
	these changes will be reverted.

Possible Solution(s)

In order to reinstall after the above, I deleted the entire .rustup folder from C:\Users\my-user-id and was then able to re-run the installer successfully.

The output from the successful re-installation is here:

> C:\Users\my-user-id\Downloads\rustup-init-x86_64-pc-windows-msvc_bleeding_edge\rustup-init.exe

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  C:\Users\my-user-id\.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  C:\Users\my-user-id\.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  C:\Users\my-user-id\.cargo\bin

This path will then be added to your PATH environment variable by
modifying the HKEY_CURRENT_USER/Environment/PATH registry key.

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload its PATH environment variable to include
Cargo's bin directory (%USERPROFILE%\.cargo\bin).

Press the Enter key to continue.

Notes

There were quite a few retry messages during the original installation (which succeeded) but they seemed to complete successfully so I ignored them.

My user account is a member of the local Administrators group but I was not running PowerShell as Administrator.

Start by reproducing the Windows re-installation with the bleeding-edge rustup-init.exe and the reported .rustup paths. Investigate the failed rename of the rust-docs directory and verify that reinstallation succeeds without requiring deletion of the entire .rustup folder.
