    I tried all of this and it still did not fix my error.

    There were problems installing some updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:

    Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.259.209.0) - Error 0x80070643

    protection definition update failed.

    "Protection definition update failed. Error Code: -2147023278

    I Haven't updated my windows defender since December last year I tried updating it today and got this:

    "Protection definition update failed.

    Error Code: -2147023278

    Error description: Another installation is already in progress. Complete that installation before proceeding with this install"

    Now the problem is I'm not installing anything so why is it showing this message?
