In fact are still there because i uninstalled them as the service on the task bar NEVER starts, says "IRST service not runninig" so it errors on the Even Viewer...same issue like MEI that drives me crazy from time to time.

I suspect, that you just have uninstalled the Intel RST Software from within the Control Panel, but this action does not uninstall the Intel RST driver!
By the way: I do not recommend to install the Intel RST Software for AHCI users, because they dont benefit from it (it may even drop the performance because of the services, which are running in the background).
If you want to get the Intel RST Software reinstalled, you should make sure, that the .NET Framework 3.5 is already running, before you run the installer of the Intel RST Drivers & Software Set. The MS Software .NET Framework 3.5 is required for the Intel RST Service and Console software.

I don't use RAID anymore so if you say that installing will give me less performance no way. So how can i uninstall ? i go over the drives and select uninstall on each ? so it reverts back to windows iastor ?

There is no Windows generic AHCI driver named iaStor.sys.
If you want to uninstall a driver, you enter the Devce Manager and just right click onto the related device (e.g. "Intel(R) SATA AHCI Controller") and choose "Uninstall". After the next reboot the Windows hardware detection will install the generic driver (e.g. the MS AHCI driver named msahci.sys resp. storahci.sys).

Fernando, greetings and many thanks for the informative post. In your opinion, which do you think would be the most appropiate (speed and boot times wise) RSTe and RAID ROM for a system with a Gigabyte Z87X-OC with RAID ROM 12.7.0.1936 set as AHCI in BIOS, IRST 13.2.4.1000 (driver only) and a Samsung 850 PRO 1TB SSD + 3TB ST3000DM001 Seagate hard drive?

Thanks for reading-

but you don´t recommend the newest: v13.5.0.1056/v4.1.0.1046 WHQL right ? so wich ones ?

---

It is not easy to recommend a special driver for a special chipset without having any own experience with such system.
These are the AHCI drivers I would try and compare:
1. Intel RST v13.1.0.1058 WHQL
2. Intel RSTe v3.8.1.1006 WHQL
3. Intel RSTe v4.1.0.1046 WHQL
The original Intel RST drivers v13.5.0.1056 don't support your system in AHCI mode. If you want to test this driver, you will have to choose the modded varariant of it (Note: In this case you have to force the installation by using the "Have Disk" button).

So weird Fernando i have all net framework installed since 3.5 and above, but every install keeps saying the same...not compatible platform

Please post the HardwareIDs of your currently running Intel SATA AHCI Controller, which is listed within the "IDE ATA/ATAPI Controllers" section of the Device Manager (right click onto it > "Properties" > "Details" > "Property" > "HardwareIDs").
