winapi - Autohotkey unable to kill a process -


i have facing issues svchost going out of control @ times , making system unstable. kill manually, decided write ahk script automatically everytime if starts using memory.

#noenv  ; recommended performance , compatibility future autohotkey releases. #warn  ; enable warnings assist detecting common errors. #singleinstance force   ;-------------------------------------------------------------- ;    variables ;-------------------------------------------------------------- minmemmb = 200 mincpupercentage = 50  loop {     process in comobjget("winmgmts:").execquery("select idprocess, percentprocessortime, workingset win32_perfformatteddata_perfproc_process name '%svchost%'")      pid = % process.idprocess     cpu = % process.percentprocessortime     mem = % round(process.workingset/1000000)     formattime, time      if (cpu > mincpupercentage or mem > minmemmb)         {             process, close, %pid%             sleep, 2000             if errorlevel = %pid%                   fileappend,                 (                     killed, %pid% , %cpu% , %mem%, %time% `r`n                 ), log.csv             else                 fileappend,                 (                     failed, %pid% , %cpu% , %mem%, %time% `r`n                 ), log.csv         }  }

my code works fine in identifying when svchost has exceeded accepted amount of memory should take. fails in killing it. log full of entries this:

failed  624 0   1036     11:15 pm wednesday  may 13 2015 failed  7408    68  65   12:36 thursday   may 14 2015 failed  7408    92  121  12:37 thursday   may 14 2015 failed  7408    80  142  12:39 thursday   may 14 2015 failed  7408    55  176  12:39 thursday   may 14 2015 failed  7408    99  149  12:46 thursday   may 14 2015 failed  7408    80  150  12:53 thursday   may 14 2015

can me in this? should use run + taskkill instead? or there wmi command can use?

thanks.

killing svchost.exe (service host process) bad idea. instance of svchost takes care of multiple services , if kill services run under stop.
should rather try find out service causing system become unstable, find out program service part of , update or uninstall program... or in worst case stop service.
disable service keep starting automatically when windows does.

i recommend process explorer sysinternals. hover on svchost process , tooltip show services hosts.

to disable or stop service go here: win+r -> services.msc -> enter

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
