Is this on the same exact computer? Did you upgrade the OS or do a fresh install of windows 10?
Did you do all the OS updates? Windows 10 might be sluggish for a while until everything is updated. Is the computer reasonably spec'd or very old (e.g. sufficient RAM)?
Are you using any unusual antivirus or security software?
Are these plain LabVIEW programs or do they involve hardware and third party drivers?
Is the HD very full?
What else is running on the PC? The W10 task manager is very informative and detailed.
Is the problem with all LabVIEW programs or just with one?
Yeah, it shouldn't be such a big difference, and since the thing that's changed is the OS i bet it's an OS issue. How's the driver situation? If you don't have a fitting graphics driver it can be really sluggish.
Didn't you say you did a clean install of windows 10? How can the drivers be old? (Did you insert an old driver CD/DVD that came with the system originally? Usually a bad idea...)
Is there anything unusual in the device manager? (hardware with question marks, etc.). How about the mouse driver? USB drivers?
Is the computer BIOS possibly old. Maybe there is an update that makes it more compatible with windows 10?
Are you using software disk encryption?
Did you check the HDs for errors?
The installation was carried out by the company network. I do not know what driver exactly was installed.
Have now installed the current drivers for the device from Fujitsu, but also no improvement.
This issue is most likely not related to LabVIEW. I had a similar issue. A wild guess: try disconnecting the network cable. It could be the antivirus policy that has this effect. It may sound weird but that has happened to me. Everything ran perfectly except when the network cable was put in on any of the customer's PCs. It turned out that it was something with the antivirus policy when connected to the company network that totally hogged our application. If your application writes data to files on disk, especially if it is often and the files are large and/or many, that could be the reason.
