Build 224 is a Beta 2 build of Windows 95, compiled on 28th October 1994. It was released on Fall COMDEX 1994. It is very similar to build 222.
Checked/debug problems
This build exists in both free and checked/debug versions, its SDK is also available.
However, the checked/debug version has issues booting with checked USER.EXE
. To fix it USER.EXE from the free release needs to replace the checked USER.EXE.
Some information about why Windows won't boot using checked USER.EXE after lot of kernel-debugging:
- The free
USER32.DLL
, when loading the Segment 21h from USER.EXE, which has the "Debug Windows 4.00.224" string. It checks for a word inside the segment to ensure it's valid. It should have a value of 0EAAh, but unfortunately the value taken is 6763h ("gc" in ASCII). Hence it'll lead to invalid paging of the segment. Because of that Windows will show a BSOD. - After changing the pointer to correct position, you'll be able to see the GUI with the watermark "Debug Windows" in right-bottom. However, hWnd pointers are done inside the same segment, hence
EXPLORER.EXE
will fail to load and will show an error or send "Invalid hWnd" to the kernel debugger. Setting the hWnd in debugger to 0 will let it run explorer.exe, though some issues remain (including system time in the taskbar).
