When upgrading Windows, it will create a fully new %windir% for you.
Any files an application installed files in them will be gone, and appear in a %HomeDrive%\Windows.old
If you’ve deleted that directory because you thought all your applications worked, or the Windows 10 upgrade automagically deleted the Windows.old directory by itself after some grace period , then you might be in trouble.
One of those applications is Delphi 2007. I wrote about a different issue on x64 Windows on that product before: Delphi on Windows x64: solution when project compiles fine under IDE, but not using MSBuild .
Basically it puts these files in %windir%\Microsoft.NET\Framework\v2.0.50727:
Borland.Common.TargetsBorland.Cpp.TargetsBorland.Delphi.TargetsBorland.Group.Targets
Those will be gone if you deleted the Windows.old directory.
If you are lucky , the files are also in this directory to copy back to %windir%\Microsoft.NET\Framework\v2.0.50727 and %windir%\Microsoft.NET\Framework64\v2.0.50727:
C:\ProgramData\{B59CE2E6-B15A-4F23-BD0E-72BF2ADDC3C7}\core\7EFD2DA3\6C948720
And if you’re not, you can find them here too: https://gist.github.com/anonymous/ab801cd925e5e634518fd5592eb2a46e

When accessing the VCL from multiple threads at the same time: adopted from …\DEMOS\THREADS\THRDDEMO.DPR
Great question a while ago:
[WayBack ] “Don’t access VCL from a background thread” – how to demo that? – Primož Gabrijelčič – Google+
For me, the ultimate way why not to access the VCL from a background thread is the precursor of the official threads demo that ships from Delphi 2 to Delphi XE6 in ...DEMOS\THREADS\THRDDEMO.DPR...DEMOS\THREADS\ThSort.pas ...DEMOS\THREADS\SortThds.pas
The first public showing of that demo did not include main thread protection. It originates from a session at the the 1995 Borland Developers Conference where Ray Konopka showed the below code from Bob Ainsbury.
That session reminded why this joke [WayBack ] Via the EKON20 sessions… – Jeroen Wiert Pluimers – Google+ was so funny: “When Ray Konopka enters the room you have a Raize condition. “.
The question above also made me find back this reference to BorCon95 in San Diego:

I forgot to schedule the post below. It is still relevant if you create a machine with lots of Delphi versions on it.

Thomas Pfister came with a nice solution to this question:
[WayBack ] Does anyone know how to embed a superscript Registered symbol in a Rave memo buffer? – Phillip Woon – Google+
Since Google has such bad indexing of G+, here is the solution:
procedure TForm4.RvSystem1Print(Sender: TObject);
const
SuperscriptOn = RPTFPrefix + RPTFSuperscript + RPTFOn + RPTFSuffix; // from RpDefine.pas
SuperscriptOff = RPTFPrefix + RPTFSuperscript + RPTFOff + RPTFSuffix;
var
MemoBuf: TMemoBuf;
begin
MemoBuf := TMemoBuf.Create;
try
MemoBuf.Text := 'Test' + SuperscriptOn + '®' + SuperscriptOff + ' Test';
MemoBuf.PrintStart := 0.5;
MemoBuf.PrintEnd := 8.0;
with Sender as TBaseReport do begin
PrintMemo(MemoBuf, 1, true);
end;
finally
FreeAndNil(MemoBuf);
end;
end;

Reminder to self that I one day need to write more about this enumerator:
[WayBack ] jeroenp / BeSharp.net / source / Native / Delphi / Library / Data / DataSetEnumeratorUnit.pas — Bitbucket
It’s not nearly as good as the one by Uwe Raabe, but I didn’t really update this code for about a decade as it has functioned well for me in the current state: in 2009 it was like [WayBack ] bo library – Source Code .
Code by Uwe is at [WayBack ] Dataset Enumerator Reloaded | The Art of Delphi Programming via [WayBack ] Refurbishing old code: http://www.uweraabe.de/Blog/2017/02/09/dataset-enumerator-reloaded/ – Uwe Raabe – Google+
A couple of years ago I wrote a two-part article about a dataset enumerator: A Magical Gathering – Part 1 and Part 2 . Well, things evolved a bit since then and I wondered how one would implement something similar given the current features of Delphi. Actually I am following here a suggestion from commenter Alan Clark.
So for now it’s just to document that my enumerator is there and that it works as intended.
I referenced an older version at [WayBack ] For-in Enumeration – ADUG as I used it at Spoken @ CodeRage III, December 1-5, 2008 on Delphi, database and XML related topics and Source: Conferences/2009/DelphiLive.2009/Smarter-code-with-databases-and-data-aware-controls .
A small video on how you use it is here:

It was back when Better Office and CodeGear still existed and we celebrated (late ) Gwan Tan’s 50th birthday.
O the days (:
