    WinHttpSendRequest continues to open handles on Windows Server 2016, uses limited set on Win10


    I have a WinHttp application that repeatedly sends requests via WinHttpSendRequest. When running this app on a Win10 system, the open handle count after the WinHttpSendRequest call will rise to a particular value around 370 then stay at that value.


    On a Win Server 2016 system, this call results in an increasing number of open handles that continues until I start getting network errors. At that time the open handle count will be around 65,700.


    I assume the handle count is due to some pool that WinHttp is managing, probably related to HTTP connections? Why would this count continue to increase on one system and not another ... is there some registry setting that controls this?


    Thanks in advance.

    :)

    Settings can't be opened using the built-in administrator account


    Hello,
    Unfortunately I have the same issue as Dabz from upgrading win7 to win10.
    I've tried opening settings using all the suggested methods and it will not load using my account with Administrator access nor the built-in Administrator profile. I also tried other methods not listed such as using Run. Control panel is just a stepping stone to add users in Settings.
    I'm also having explorer.exe issues, which I believe is preventing Settings from loading.
    Using cmd (Admin) I successfully created a new user profile [and granted admin access also using cmd (Admin)], however win10 will not allow this account to log on. win10 does not list this new user within control panel but it does in the start menu. win10 will not allow to log in or switch to the new account via the start menu either.
    I can access settings in Safe Mode but this will not allow me to create a new account.
    Any help/suggestions will be greatly appreciated.
    Cheers

    Overclocking / Undervolting guide for Vega 56 or 64?

    Here's a quick laundry list:

    List of software to use for overclocking and testing
    Examples:
    Wattman (and how to find and use it, like an overview, including profiles)
    Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
    How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

    Step-by step overclocking in Wattman
    Fan speeds
    Power limit
    Temp limit
    Voltages
    Core speeds
    Memory speeds

    Settings can't be opened using the built-in administrator account


    Hi guys

    I have same issue in safe boot mode with networking!

    First of all it blocks the networking

    Then states:

    Settings cant be opened using the built in administrator account sign in with different account and try again.


    Yet clicking on windows i opens settings fine


    It also states broadband blocked, yet I can happily get on the net but at first I couldn't.

    When I asked about it the guy from Microsoft tech answers couldn't understand why I wanted to use safe boot mode with networking????????

    After he did nothing to help but emailed some scripts which didn't refer to safe mode. I rebooted and suddenly safe mode with networking worked with the net but windows 10 still claims broadband is blocked!

    Im also still getting the message on trying to unblock broadband:

    cant be opened using the built in administrator account sign in with different account and try again.

    What is going on there?
