How does DefaultCollectUsage work

I want to disable statistics.
I've found so far:
https://winscp.net/forum/viewtopic.php?t=26832
and the Link
https://winscp.net/eng/docs/administration

[HKEY_LOCAL_MACHINE\SOFTWARE\Martin Prikryl\WinSCP 2]
"DisableOpenEdit"=dword:00000001
"DisablePasswordStoring"=dword:00000001
"DisableAcceptingHostKeys"=dword:00000001
"ForceBanners"=dword:00000001
"DefaultUpdatesPeriod"=dword:00000000
"DefaultCollectUsage"=dword:00000001

On 64-bit systems, a physical location of the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Martin Prikryl\WinSCP 2 (as WinSCP is 32-bit application).

But it doesn't work. Both in
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Martin Prikryl\WinSCP 2
and
HKEY_LOCAL_MACHINE\SOFTWARE\Martin Prikryl\WinSCP 2
there is no influence on the property dialogue.
What is the right combination of DefaultUpdatesPeriod and DefaultCollectUsage?

It's default. It applies only when use use WinSCP for the first time on the respective local account.
If you are already using WinSCP, just disable them in the GUI:
