Windows Explorer display delay

[pmonett]

I have a laptop and my desktop PC both still on Win7.
I also have a NAS with 4 3TB HDDs in RAID 5.
On both, I have disabled Windows Search and Indexing, because it just sucks.
I have recently had to reinstall my desktop following an incomprehensible crash that wiped the boot sector. So, reinstall and then load the backup and what ? The backup is not compatible with my Windows ? What ? Grr. Fine, just go to Windows Update and redo everything then. Two days wasted, and I found a different backup system that works.
Ok, everything's fine, except that my desktop now spends an inordinate amount of time displaying the files in the folders on my NAS.
Example : one of my NAS folders has 534 files and 6 folders. If I right-click and ask for Properties, the result is immediate. When I click on said folder in Windows Explorer, it takes the system no less than 13.2 seconds (yes, I timed it) to display a random list of growing file names, before finally sorting them out in a useful way and giving me the right to work again.
On my laptop, the same display is immediate.
Obviously, there is some setting that I have on my laptop that I don't have on my desktop anymore, but what is it ?
Oh, and yes, I have disabled Windows Search on the desktop, just like the laptop.
Can anyone give me a clue ?

Thanks in advance,
Pascal.

I've got nothing to hide, and I demand that you justify what right you have to ask.

This is one of those annoying "green bar of death" things. The green bar runs across the screen and seems to be running on the spot when it reaches 98%. Just lookup "green bar of death" on the internet. Common reasons:

1) Check what services are running. Is there any service that is taking a huge amount of time?
2) have drives been mounted from any machines that are not switched on (type net use - all drives should say OK)
3) have drives that no longer exist been mounted (type net use - all drives should say OK)

Sometimes a reboot solves it but it is annoying to have to do this without knowing what the underlying reason is.
Sometimes killing off windows explorer then rebooting solves it.
