The Scoop repository lists this first time Scoop install command at [Wayback/Archive] ScoopInstaller/Scoop: A command-line installer for Windows. – installation:
Run the following command from a non-admin PowerShell to install scoop to its default location C:Users<YOUR USERNAME>scoop.
iwr -useb get.scoop.sh | iex
[Wayback/Archive] ScoopInstaller/Install: 📥 Next-generation Scoop (un)installer is very similar:
Run this command from a non-admin PowerShell to install scoop with default configuration, scoop will be install to C:Users<YOUR USERNAME>scoop.
irm get.scoop.sh | iex
# You can use proxies if you have network trouble in accessing GitHub, e.g.
irm get.scoop.sh -Proxy 'http://<ip:port>' | iex
The Scoop homepage at [Wayback/Archive] Scoop.sh is not much better:

A few years back this trick was shown to screw up %windir%\system32 [Wayback/Archive] Patrick Doyle on Twitter: “@SwiftOnSecurity @RoseAreaZero Delete any file in three easy steps: > takeown /F "example.ext" > icacls "example.ext" /grant "%USERNAME%":F > del "example.ext"“.
Like [Wayback/Archive] SwiftOnSecurity (@SwiftOnSecurity) / Twitter (see the long thread further below), I was expecting that Windows would either prevent you from doing this at all, or allow for easy recovery with System File Protection (now Source: Windows File Protection).
That didn’t prevent or recover it back then.
I wonder if that has been changed by now.
From the above Tweet:
Delete any file in three easy steps:
> takeown /F "example.ext"
> icacls "example.ext" /grant "%USERNAME%":F
> del "example.ext"

This batch file works for modern Click-to-Run (sometimes called ClickToRun, Click2Run or C2R) based Office installations (note the odd lowercase microsoft shared which indeed is the actual directory name):
if exist "%CommonProgramFiles%\microsoft shared\ClickToRun\OfficeC2RClient.exe" (
"%CommonProgramFiles%\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user
) else (
echo could not find the Office Updater
)
This for sure does not work for MSI based Office 2013 and lower (which are updated through Windows Update anyway). Since I only have 2021 online (Click-to-Run) installs and higher to test with: those work fine.

I could not find a reliable per-user setting that works with just logoff/logon for Windows 11 like I found for Windows 10 in Disabling the Windows 10 and Windows 11 news (and weather) feeds.
So (for now?) there is only a global Globally which needs admin rights and a logoff/logon sequence:
:: requires admin
reg add "HKLM\Software\Policies\Microsoft\Dsh" /v "AllowNewsAndInterests" /t REG_DWORD /d "0" /f
echo logoff/logon to apply the change, or restart Explorer
Via:

Often I need to generate passwords or uuids (on some systems called guids). I usually try to do that in a relatively platform agnostic way as I use MacOS, Windows and Linux in various mixes for many reasons (for instance that I have had developed quite hefty RSI in the early 1990s of the and the best keyboard/pointing-device combination for is the MacBook built in keyboard/touchpad combination so basically MacBooks are my window to all other operating systems).
Generating randomly with a good random number generator them makes sense as for most usage, it is important that both passwords and uuids are hard to guess which means having an entropy that is as high as possible.
A cool thing about OpenSSL is that:
- most of not all systems have it installed (it was no coincidence I published Installing OpenSSL on Windows a few days ago)
- it has a very good pseudo-random number generator and as of [Wayback/Archive] OpenSSL version 1.1.1 first released in 2018 has solved the problem around [Wayback/Archive] Random fork-safety – OpenSSLWiki, see [Wayback/Archive] Our Review of the OpenSSL 1.1.1 Random Number Generation Update – OSTIF.org.
- it supports various useful output formats
hex (hexadecimal) and base64 (next to the default of octet – or by today’s naming convention byte – output)
The easiest to generate are passwords. Yes I know that password managers can do this too, but there are some systems I cannot use them on or sync between them (don’t you love the corporate world) so my aim is to use a random password generator in a platform agnostic way which usage is easy to remember.

That feeling you have been living under a stone since 2014: [Wayback/Archive] finding duplicates – voidtools forum
1.4 Beta has both dupe: & sizedupe: functions.
(In the Index, you need to index the file size & also enable Fast size sort.)
You can combine them, something like:
> dupe: sizedupe: c: file:
Or even add a size to it:
> dupe: sizedupe: c: file: size:>2MB
Note that that finds file name AND (I believe its an AND) file size duplications – anywhere, not necessarily limited to C:, & also that name AND size are the only qualifications for “duplication”, as in files meeting that criteria may not be (byte-by-byte) “duplicates”.
A partial excuse is that these never made it to the changelog at [Wayback/Archive] www.voidtools.com/Changes.txt or [Wayback/Archive] www.voidtools.com/BetaChanges.txt.
It is in the documentation since May 2017 at [Wayback/Archive] Searching – voidtools though:

For a long time, I have ran with the runelevated.bat in [Wayback/Archive] Run an Elevated command using that: “net file” returns errorlevel 1 when not UAC, and “PowerShell Start-Process” has a “-Verb RunAs“; see the answers at http://stackoverflow.com/questions/7044985/how-can-i-auto-elevate-my-batch-file-so-that-it-requests-from-uac-admin-rights for more information
By now, I would just prepend this oneliner into each batch-file needing elevation:
@pushd "%~dp0" & fltmc | find "." && (powershell start '"%~f0"' ' %*' -verb runas 2>nul && popd && exit /b)
Both the initial batch file and one-liner are from [Wayback/Archive] windows – How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required? – Stack Overflow (thanks [Wayback/Archive] Ir Relevant, [Wayback/Archive] ceztko, [Wayback/Archive] Jamesfo, and [Wayback/Archive] PDixon724)
Note that the net file trick below should actually be repeated twice. This is explained in [Wayback/Archive] windows – Batch script: how to check for admin rights – Stack Overflow (thanks [Wayback/Archive] zumalifeguard), but wait: there is even a better solution!
The fltmc trick above works much better than the net file trick and is available from Windows XP and up, see [Wayback/Archive] windows – Batch script: how to check for admin rights – Stack Overflow (thanks [Wayback/Archive] npocmaka).
Oh: on systems where I have full installation control, I always install gsudo, see gsudo (sudo for windows).

Sometimes I need [Wayback/Archive] Redirect Checker | Check your Statuscode 301 vs 302 on the command-line, so cURL to the rescue: [Wayback/Archive] linux – Get final URL after curl is redirected – Stack Overflow. The relevant portions of answers and comments further below.
TL;DR:
Since I prefer verbose command-line arguments (you can find them at the [Wayback/Archive] curl – How To Use on-line man page) especially in scripts this HTTP GET request is what works with Twitter:
% curl --location --silent --output /dev/null --write-out "%{url_effective}\n" https://twitter.com/anyuser/status/20
https://x.com/anyuser/status/20
This failed (twitter dislikes HTTP HEAD requests):
% curl --head --location --silent --output /dev/null --write-out "%{url_effective}\n" https://twitter.com/anyuser/status/20
https://twitter.com/anyuser/status/20
Notes
Given so many of my scripts now run on zsh, I added the new-line because of command line – Why does a cURL request return a percent sign (%) with every request in ZSH? – Stack Overflow. You can strip that bit.
Note that these do not perform client side redirects, so they do not return the ultimate originating URL https://x.com/jack/status/20 (which was the first ever Tweet on what was back then called twttr) as Twitter on the client-side overwrites window.location.href with the final URL. Similar behaviour for getting the Twitter user handle of a Twitter user ID, more on Twitter tricks below.
