Last week I found out that I had some Windows ATOM issues before, but this beats them easily was still a draft in stead if in the blog queue.
I got reminded to it by someone asking on Telegram about
“Do I need to use GarbageCollectAtoms in Delphi? I used it in delphi 7, but I dont know what is benefit. 😐”.
The short answer is: yes, if your Delphi application does terminate in a way that the Controls unit cannot cleanly unload (and cannot free the Windows atoms) or leaks Windows atoms in a different way. I have been in that situation and that’s why I wrote the above blog post that got published in 2016.
The longer answer is likely no, both the Windows atom and registered Windows message table share a heap and that registered VCL Windows message leaking bug got fixed some 10 years ago in Delphi XE2, see:

lFor Mac keyboard keys, almost all (except the old solid and open Apple logo’s) have a Unicode code point, see for instance the modifier keys from the [WayBack] List of Mac/Apple keyboard symbols · GitHub (the “Alt” column has a solid Apple logo in the bottom right; on non-Mac systems it will look differently as it is in the Unicode private range: [WayBack] Unicode Character ” (U+F8FF): ‘<Private Use, Last>’):

[WayBack] How to turn on automatic logon in Windows
Describes how to turn on the automatic logon feature in Windows by editing the registry.
Most archivals of the above post fail with a 404-error after briefly flashing the content, but this particular one usually succeeds displaying.
It is slightly different from the one referenced in my blog post automatic logon in Windows 2003, and because of the archival issues, I have quoted most of it below.
A few observations, at least in Windows 10 and 8.1:
- Major Windows 10 upgrades will disable the autologon: after each major upgrade, you have to re-apply the registry patches.
- If the user has a blank password, you can remove the DefaultPassword value.
- Empty passwords allow local logon (no network logon or remote desktop logon), no network access and no RunAs, which can actually help improve security. More on that in a later blog post
- For a local machine logon, you do not need the DefaultDomainName value either (despite many posts insisting you need them), but you can technically set it to the computer name using
reg add "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d %ComputerName% /f
- If another user logs on and off, the values keep preserved, so after a reboot, the correct user automatically logs on
- you need a full reboot cycle for this to take effect
- The AutoLogon tool does not allow blank passwords
I wrote a batch file enable-autologon-for-user-parameter.bat that makes it easier:
if [%1] == [] goto :help
:enable
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f
:setUserName
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d %1 /f
:removePasswordIfItExists
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /f
if [%2] == [] goto :eof
:setPassword
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d %2 /f
goto :eof
:help
echo Syntax:
echo %0 username password
