I have repeatedly tried to download and install Windows 10 update 1909 on my HP All-in-One 24-f1xx, which I purchased on 1/26/2020. Each time the download fails to complete and various error messages result. At one point in early February, the Windows 10 download update was hung up for hours (at 91% completion) before it failed to complete the installation. I am not an expert in these matters and would appreciate some practical help to complete this download and installation. Thanks. John
