how to make Windows 10 fault tolerant to power off

how to make windows10 fault tolerant to power off when using LabVIEW

[RavensFan]

What exactly to you mean by fault tolerant?

• Intentional power off or accidental power off?
• Is this actually a LabVIEW question or a Windows 10 question?
• What is happening now that you are trying to do differently.
• When you lose power, what do you expect LabVIEW to do?
• Or do you want a certain behavior when power returns?
• Why not have a battery backup on the PC so it rides through power losses?

Lots of questions, but no details in your message to go by.

I mean  make windows10 tolerant to power loss,so it doesn't corrupt its discs and labview returns as normal when power is restored. using battery backup is not an option.

Some ideas here

From the LabVIEW PoV, everything you save should be redundant and have a validity check. So, when the system crashes during a save, the check will fail and the other file is used. So the storage should alternate between the two files. Always write to the oldest file, and always start opening the newest file. If the newest file is corrupt, use the other (and save it over the newest).

That doesn't prevent Windows from getting corrupt though...

LOL Good luck with that.

People have been trying to figure out how to stop Windows from corrupting it's HDD on a bad shutdown since the 1990's. 

BTW: The only real solution would be to run something like Windows Embedded.

Actually while Windows Embedded is supposed to be a bit more robust in that respect it is no guarantee that the flash disk won't get corrupted somehow when the power goes down at the moment when important files were updated.

The real solution is to use an Uninterruptible Power Supply (UPS), and maintain it. the battery in there won't live forever!

It has an internal battery storage and monitors the mains line. When it detects a power fail it will switch over to battery operation and send a signal to the PC that it needs to properly shutdown. Depending on the UPS (and the money you throw against it) you can get a few minutes of operation to safely shutdown the system to several hours of backup operation before the system has to be shutdown.

Yes, but the original poster also stated:

Also doesn't Windows Embedded use a write protected system disk, so the base OS can not be corrupted?

Sounds like a case of:

Patient: Doctor it hurts when I push on this spot!

Doctor: Then don't push on that spot!

I'm sure you can set it up like that. But that requires you to have either two flash disks or at least partitions. Windows without anywhere to write registry and other file changes is pretty unworkable.

I worked as IT on a trading floor where UPS was not an option, also.  (Presumably because the traders didn't want their computers down for even five minutes, but I never got an official reason.)  Then a power glitch took out 2/3 of the computers on the trading floor and they decided maybe it was time to go the UPS route.
