Windows Push Notifications User Service using all 32GB of my RAM.

A process by the name of svchost.exe 'Service Host: Windows Push Notifications User Service_[INSERT_NUMBERS_HERE]' is using up all my memory. Typically using at most 23% of my CPU.

I need to force end task on Task Manager every time and it seems to appear randomly. Is this a virus or just a bug? What do I do to fix this?

    Hi Gon Rod,

    Welcome to Microsoft Community.

    The presence of "Service Host: Windows Push Notifications" is normal and the system may depend on this service to push some messages.

    In your case, however, the process does not have a service number, it does not seem to be a standard push notification process.

    It appears that the process is not properly initialized to be associated with some specific application.

    Would you mind sharing more information about this issue with us?

    • Is the problem a recent phenomenon? Or has it existed for a long time?
    • Were there any special events in the device before the problem occurred? For example, system update, driver update, application update, BIOS update?
    • Is the situation the same when observed in a relatively clean environment (for example, new local account, clean boot)? Create a local user or administrator account in Windows - Microsoft Support Clean Boot starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem. These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step. Please be careful not to disable any services related to security credentials or security authentication, such as TPM, Security, Credential.
