I wish I had reassuring news for you -- but I don't. The issues you described can all be caused by the same problem -- failing drive. When that happens, you have inconsistent and/or failing boot, missing files, changed settings, and failing Windows Updates -- due to file corruptions on the drive.
And yes, the problems could have other causes but this one issue is central to all of them.
So, let's check the drive first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.
If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024
If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.
If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.
