This is not my first attempt to compile apps for Alpha Release but the first time I have succeeded. As I said before, Alpha Release contains everything we need (it is the most complete Windows 1.0 pre-release) but we do not have the proper libraries. I tried to compile some sample again yesterday and I decided to disassemble and compare the (failed) output to the samples Microsoft compiled 35 years ago. I noticed my output contained a chunk of extra code (__cinit, __exit, __ctermsub, unknown, __astart, __cintDIV, __amsg_exit, __NMSG_TEXT, __NMSG_WRITE, __setenvp, __setargv, unknown2, unknown3, __nullcheck and __myalloc) from SLIBC's crt0 and they caused all those errors I have encountered before. I guess it should be possible to replace those functions with dummy ones but that would be a lot of work so I started to look for libraries designed for Windows and I tried RTM's SWLIBC.LIB. It worked better than Microsoft C Compiler's SLIBC.LIB (designed for DOS) but still failed with an unresolved external. I then tried SWINLIBC.LIB and failed with 8 duplicated functions but no unresolved externals. That was a good sign so I renamed those 8 functions (replaced the last letter with 2) then all samples compiled and linked without a single error! I then tested the samples I compiled and they worked perfectly on Alpha Release - icons can render correctly as well.
Now we can port some apps to Alpha Release but since we already have all the samples, porting apps from RTM's SDK wouldn't be fun at all so I decided to try Charles Petzold's Birthday Cake application. I encountered 48 errors the first time because I used the wrong WINDOWS.H but I managed to fix all the actual errors in the end.
The biggest problem was whenever I click Decoration → Settings, it fails with invalid module handle. I soon discovered DialogBox wants another parameter and with that fixed, it will open the settings dialog. There was another problem - clicking OK or Cancel does nothing so I add OK and Cancel to the menu (like all other Alpha Release apps). Well, clicking any of the options gives me the invalid task handle error so that was definitely not the right thing to do. jb881122 pointed out that SettingsProc should have an extra parameter (lpResult) because Alpha Release's MapModes does and with that parameter added, the setting dialog became functional - but not fully.
Clicking the checkbox does nothing and we have tried to fix it (by messing with SendDlgItemMessage CheckDlgButton) but none of the fixes were good. With fixes applied, it is possible to add firework and flashing effects but there is no way to uncheck the box once checked so it is probably a better idea to leave that for someone more experienced to fix.

Since we have access to ~10% of the Beta Release SDK (all Windows libraries, some development utilities and sample source code), it is possible to develop applications for Beta Release. API changes (such as different ordinal numbers and application initialization procedure) prevented us from using Windows 1.01's SDK to compile apps for Beta Release so we must use the incomplete SDK. The main problem here is still SLIBC.LIB (more precisely, the duplicated function names and unresolved _main function). I have successfully compiled Beta Release apps with Microsoft C Compiler 4.00's libraries before but it will not work due Beta Release being incompatible with later SLIBW.LIB. I tried to use Microsoft C Compiler 3.00 and 4.00's SLIBC.LIB to compile Windows Hello for Beta Release and it failed with 2 errors (unresolved externals in the winstart function). I managed to get the app to start by manually removing the bad image attribute from the NE header and running RC but the application icon did not not render properly.
Since I managed to compile Alpha Release apps with a modified SWINLIBC.LIB, it wouldn't hurt to try that on Beta Release and it worked! Then I tried to port some SDK programs from Alpha Release and RTM's SDK. Apps written for Beta Release and later builds are compatible at source level (except for some font and OEM stuff we rarely use) so RTM's SDK programs can be compiled for Beta Release without any modifications. Alpha Release apps are a bit hard to port because some functions (such as DialogBox) have different number of parameters and they are more likely to crash. Below is Beta Release with Hello (from Beta Release), Font Tester (from RTM), Shapes (from RTM) and MapModes (from Alpha Release) running:
More complex apps such as Birthday Cake can of course be recompiled for Beta Release as well and it is fully functional (except for the font part because Beta Release does not have the Script font):

This is not as exciting as the previous 2 because most apps compiled for RTM will run on Premiere Edition but since we have one of those sample programs and WINDOWS.H, I decided to make a toolchain for it. Actually, I did this more than a month ago and shared it on Discord but I'll use this opportunity to share it on the forums as well. We don't have any libraries that came with Premiere Edition's SDK and Microsoft C Compiler 3.00's libraries does not link properly so I decided to use Microsoft C Compiler 4.00 for this and it worked perfectly. This is not new at all but Premiere Edition's Hello Windows does say 1.01 in the about dialog:
Well, I am not going to port any apps from RTM's SDK because most RTM programs does work on Premiere Edition (including Birthday Cake) so if you want to port those apps yourself, go ahead.
Please note that I do not have the Windows Toolkit, Beta Release and Premiere Edition's SDK so all my toolchains involves a few hacks (such as renamed functions). If you are going to use weird library functions, there is no promise that it will work even though it should. Please don't use
Edit: Updated the Alpha Release and Beta Release toolchains to include medium model libraries. Moved some include files to Beta Release's LIB directory and removed them from the Birthday Cake program. I did not bother to do the same thing for Premiere Edition's toolchain because you can just use the RTM SDK to compile apps for it.
