Inspiron 5570 laptop, Win10 Pro, 2TB HDD (replaced with an NVMe M.2), core i7-8550U, 16GB RAM, Radeon 530 4GB VRAM + integrated Intel 620
From day one I've been getting a delay when I open a file, up to 10 secs. Explorer says it's "working on it." Not every time but most of the time. So I replaced the HDD with a 2TB Intel 660p NVMe M.2. HD Tune reports AVERAGE READ is 907 MB/s. Still the delays persist. The drive has >60% free space, no peripherals, no scheduled tasks, no registry tweaks. The Indexing Service is on.
Can Win10 be the culprit here? If not what could be causing it?
