A while ago, I needed to generate GUIDs on any Windows console so performed a [Wayback/Archive] generate guid windows terminal – Google Search, found [Wayback/Archive] Generate a GUID in Windows 10 (Globally Unique Identifier) and came up with this generate-guid.bat file:
powershell [guid]::NewGuid()

Note that the below methods likely will cause security warnings if a Windows machine has been properly configured, but in most cases at least one of them works.
curl --url https://speed.hetzner.de/100MB.bin --output %TEMP%\100MB.bin
certutil | Microsoft Docs (at least Windows 7 and up; needs UAC elevation)certutil.exe -urlcache -split -f https://speed.hetzner.de/100MB.bin %TEMP%\100MB.bin
powershell.exe -Command (New-Object System.Net.WebClient).DownloadFile('https://speed.hetzner.de/100MB.bin','%TEMP%\100MB.bin')
I think it works for all versions of curl, certutil, and PowerShell though I did not have anything older than up-to-date Windows 7 (having PowerShell version 3) and recent to test on.

Reminder to check-out of the 2015 issue mentioned in the tweets below has been had any progress.
At the time of tweeting, choco has no notion of [Wayback/Archive] status.chocolatey.org which would be very helpful to point to in case of errors on time-outs on chocolatey server calls especially if it could interrogate and inform of maintenance windows and outages when things fail on the client side.

A few years back I suddenly had almost all my .nupkg files that Chocolatey uses to track installed software become zero sized.
So I posted a question at [Wayback/Archive] Need help restoring .nupkg files having zero size · Discussion #2765 · chocolatey/choco which got this answer:

More than a decade ago I wrote about Programmatic alternatives to Windows-L keyboard shortcut (SwitchUser / LockWorkstation).
Still, I see many scripts invoke rundll32.exe or to call the [Wayback/Archive] LockWorkStation function (winuser.h) inside user32.dll. Don’t!
The BOOL LockWorkStation()function has a calling convention that is incompatible with rundll32.exe () which will corrupt the call stack likely will lead to random problems as after two decades, this post from Raymond Chen still holds: [Wayback/Archive] What can go wrong when you mismatch the calling convention? – The Old New Thing

I have had these two batch files on my system forever:
sha1.bat::: https://superuser.com/questions/245775/is-there-a-built-in-checksum-utility-on-windows-7 :: https://www.mcbsys.com/blog/2017/03/use-certutil-to-get-file-hash/ :: Windows 7 has case sensitive Hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512 certUtil -hashfile %* SHA1
sha256.bat::: https://superuser.com/questions/245775/is-there-a-built-in-checksum-utility-on-windows-7 :: https://www.mcbsys.com/blog/2017/03/use-certutil-to-get-file-hash/ :: Windows 7 has case sensitive Hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512 certUtil -hashfile %* SHA256
But I forgot to blog about [Wayback/Archive] Use Certutil to Get File Hash | MCB Systems mentioning:
on Windows 7, the hash algorithms are case-sensitive. Be sure to type, for example, “MD5”, not “md5”. On Windows 8.1 and 10, case doesn’t matter
I did mention the first link in “error: invalid object 100644” “git svn”, though only in a by-line. So thanks [Wayback/Archive] user64996 for asking and:
CertUtil is a pre-installed Windows utility, that can be used to generate hash checksums:certUtil -hashfile pathToFileToCheck [HashAlgorithm]HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512So for example, the following generates an MD5 checksum for the fileC:\TEMP\MyDataFile.img:CertUtil -hashfile C:\TEMP\MyDataFile.img MD5Original solution by Laisvis Lingvevicius
To check if the hash is correct, you can use this Powershell one-liner:if ( $($(CertUtil -hashfile C:\TEMP\MyDataFile.img MD5)[1] -replace " ","") -eq "your_hash" ) { echo "ok" }
powershell get-filehash -algorithm md5 <file_to_check>
