Windows 8 how to set the congestion provider to ctcp

[artins90]

Guys I've installed windows 8 and as usual I tried to optimize the tcp, the other setting from your guide work just fine but the congestion provider says that the syntax is wrong, i'm not a tcp or cmd expert could you kindly check this out for me?

Here is a screenshot

It only works with Windows Vista, 2008 & 7. XP x64 and 2003 can be tweaked by editing the registry.

netsh int tcp show global lists the command so it must work in Windows 8 the problem is how to set it, there has to be a way to activate ctcp

Windows 8 is not officially done or out yet.
So I doubt Philip has invested a lot of time fiddling with it, knowing that code could change and whatever time he spent would have been wasted since he would have worked on a beta/pre release version.
Supposedly the final version will be released to developers/partners on Aug 15 (a date which has not happened yet)

But since Windows 7 came out....I've left it alone, default settings. Works great!

last i checked netsh was still in w8 but wasnt activated.maybe the latest version unlocked it,even if it is unlocked.we ll need to relearn netsh because ms changed the format(how to word command)but on a side note it is way more powerfull then before.on server side of things just enabling dctcp alone is gona be a huge feature.sadly for philip and all this means a new section will need to be added for w8 alone to show how to do netsh stuff but in window 8(ya it is a bit more complex and awkward)

Uhm...yes....but do you care to look at the date of my reply? HmmmMMMM?
And not officially released to the public until Oct 26th as of latest date.

oops, did not see date. and to me being on technet and MSDN is public anymore. maybe few years back that wasn't the case but now it is different, that is why MS had to change policy for technet as regards keys and such

Yeah...been playing with the release versions since...man, last spring or winter. But I don't consider them fully baked until it's announced like it was recently, and not public until it's officially released to public.

But like Windows 7...I still say "Leave it alone". Doesn't need tweaking like XP and prior.
Just a tablet OS to me anyways...so zero interest....it won't hit much in the business area anyways...even that "N/Pro" version. Following Microsofts pattern of "every other" OS release being good, then bad, then good..then bad....Win8 will be the Vista of the upcoming year.

tried setting this using the powershell command

set-nettcpsetting -settingname custom -congestionprovider ctcp
this gives the error " Property CongestionProvider is read-only "
there has to be a way to enable this.

[artins90]

Did anyone figure out how to enable it?

[RaisinCain]

There is no way to enable what you are looking for... PERIOD. Just leave it alone. There is no point in trying to change the setting.

Have you tried running command prompt as an administrator ? Only elevated command prompt would be able to change it.

use this-netsh interface tcp set global congestionprovider=ctcp-worked for me on the run as administrator command prompt by right clicking command prompt and click run as administrator
