Re: Unable to install Windows 10 update 1903 on Yoga C930

I also tried that, it updates the driver but leaves one file unchanged (precisely the one that is checked by Windows update).

It's a little annoying :-)

First, make a backkup (you probably already did that). Rename the suspect file from .sys to .old and see if 1903 will load. Odds are, Windows will replace the file. If it doesn't, make a mental note and continue on, normally. If anything seems amiss, you can rename the file back or restore from your backup. 

 

You didn't, by chance, push 1809 on your 910, did you? I went from 1803 - 1903 since 1809 was blocked from the 910.

This does appear to be a recent change in the deployment of 1903, which may be why some of us got it before the change was made:

Solve it!

 

First, I uninstalled RSIT but I also had to look for the file iastora.sys and manually delete it.

Then, I ran the update successfully and reinstalled RSIT.

 

It is working fine so far :-)

Re: Unable to install Windows 10 update 1903 on Yoga C930

Hello,

 

I am having the same issue on my C930, but in the device manager and/or the add/remove programs prompt, I don't see anything that says Intel Rapid Storage Technology. When I try to install RSIT, it tells me my platform is not supported. I removed iastora.sys but that caused a "you need to restary your PC to finish installing firmware" endless loop.

 

What exactly did you uninstall? A driver or a program, and where did you find it?

 

Thanks for any help or ideas! I need this update for a program I am trying to run.

 

Isaac

Try:

http://www.uninstallhelps.com/how-to-uninstall-intel-rapid-storage-technology.html

 

Or if you can't uninstall it you could probably disable it :

 

So just click on Start, type in MSCONFIG, then go to the Startup Tab and then uncheck the Intel stuff, then ok and restart.

Re: Unable to install Windows 10 update 1903 on Yoga C930

That's what was frustrating, there is no Intel Rapid Storage Technology program anywhere. Nothing to uninstall in add/remove programs, and no devices in the device manager that seemingly would use it.

In the end, the solution that worked was to delete the iastora.sys file from C:\Windows\System32\drivers. See this post for reference:

Thank you for your help!

What are the consequences of deleting or renaming the iastora.sys file? That seems to be the only solution for me as well.

As I said it's totally useless, so just forget about it.

 

It's strange that you have it on your PC if Intel RST isn't installed.
