Yes. As a result, it will be used in past version.
For those who want to see the difference on uCode,
please check my updated article (Section 3.1): [OFFER] MSI MEG Z390 ACE (7B12v1B1 - uCode/Chipset/HPET - BIOS MOD)
Also, I updated the Z390 Ace BIOS Mod with 2 uCode for reference which are:
- AA (the earilest uCode for 906ED)
- EC (the newest? uCode for 906ED)
Moreover, AA/BE/EC supported TSX
(In my case, if the uCode is patched from Windows update, the TSX wonât enable even modified Registry)
In my case, TSX is displayed with CPU-Z. However, I do not know if it is actually working in the system.
In the case of me, "pre spectre&meltdown" and "currently" are almost the same in process performance.
There are several things that have not yet appeared in the old microcode version. It is a personal guess.(Kaby desktop etc. are examples. But Kaby Mobile have appeared. However, Sky and Kaby has not appeared both desktop and mobile. Some of Coffee have not appeared.)
But old version of microcode are considered to be limited to "number".
For now, Personally, the microcode is more interested in old version that have not yet appeared than later new version.
Thanks for explaining why Windows 10 had TSX enabled (with mcupdate_GenuineIntel.dll disabled) and Windows 11 had TSX disabled (with mcupdate_GenuineIntel.dll enabled) for the two images I posted here.

I force updated the Windows Update Microcode patch and BIOS microcode to ensure TSX is disabled for testing
Here is my testing result:

REG value: DisableTsx ; FeatureSettingsOverrideMask ; FeatureSettingsOverride
BIOS MC: EC
Windows MC Update Patch: KB4589212
- TSX enabled (with mcupdate dll, reg TSX enable) [surprising and weird, is it ignore dll in this situation?]
- TSX enabled (without mcupdate dll, reg TSX enable)
- TSX disabled (with mcupdate dll, reg TSX disable)
- TSX disabled (without mcupdate dll, reg TSX disable)
Therefore,
- Windows will apply microcode from BIOS while mcupdate dll not exist
- Does TSX not only depend on mcupdate dll, registry also?
- [EDIT] Different situations will show different results, if CPU-Z / AIDA64 shows TSX isnât supported, you need to check the regedit first. If still unsupported, you should uninstall the MC update patch / remove or rename mcupdate dll.
- @chinobino can you enable TSX through regedit on your Windows 11 while mcupdate_GenuineIntel.dll enabled?
If TSX is displayed on CPU-Z, that means it is working.
Sure, can you tell me the location of the keys and their values etc?

thanks
@ritizen I added the 3 new keys and set them to enabled, rebooted and now TSX is enabled in Windows 11 with mcupdate_GenuineIntel.dll enabled.
This shows mcupdate_GenuineIntel.dll & the registry are the keys of TSX
I am thankful for your assistance 
(Different uCode may not affect TSX instruction)
If Sky new microcode does not come outâŚ
The possibility of coming out will be old version that have not yet appeared.
There is point there. This is natural.
And the possibility of the content like the special version of the example will come out.
It will connected to it.
I dont understand???on my 7900X i have TSX on CPU-Z better is disable or enable??? @ritizen @chinobino for perfomance???
i use THE OLDEST microcode mod on latest bios on my mobo!!and i delete system32 mcupdateintell.dll
TSX is better for enable than disable in some cases which are required on TSX. (one of the emulator - RPCS3 rely on TSX instruction to optimise, the huge degraded result show after TSX is disabled). However, there are no any gaming benchmark (except RPCS3) that can reflect the influence of performance.
[Edit] Regarding the benchmark, due to TSX instructions involve some of thread enhancements technology, you will get some different on benchmark score between TSX on and off
In your situation, you may continue to use pre-spectre uCode on your 7900X and without mcupdate dll to perform the best performance.

Thanks a lot!yeah i have same the first cpu microcode release my 7900X and spectre meltdown disable on regedit!!!so i dont touch TSX thanks a lot!i remove mcupdateintell.dll complete
Skylake-S (1151) has been brought in line with Kabylake and Coffee Lake with microcode cpu506E3_plat36_ver000000EC_2021-04-29_PRD_D912FEAB.bin

@wendell I still canât seem to edit the original 2 posts at the top of this topic so I will just list some changes to the archive below.
-
The socket 2066 folder has been cleaned up, with CPUIDâs 50650, 50651, 50652, 50653 and 50655 moved into the socket 3647 folder (Currently I canât update the OP to show this change unfortunately).
