Poor Start up response

Hi, firstly, if you don't have a full backup- a disk image- as is so, so often advised by members here, that is your first priority.

e.g. Macrium reflect (free) + large enough external storage for image files.

You can image
a. All partitions comprising your Windows O/S- typically 4 for a UEFI installation, fewer for an MBR one.
b. All disks used
c. Any combination of the above

Having a disk image, and maintaining it periodically and routinely, means you are protected from failures, theft, fire, flood- if your backup is securely stored- and can even recover to a new disk or new PC.

Note that 'normal' disk imaging fails on a failing disk where the used part of the disk is corrupt. Hopefully that's not yet your case.

Secondly, inspect HDSentinel's report for each of the other disks as well.

And HDSentinel is a great choice.

Thirdly, and a much lower priority, as to performance, you might, having done that, compare your boot performance when the other disks are disconnected. I have found cases where other problem disks cause slow booting.

Why is your boot slow? Besides the above, consider how much free space you have on C:

How long does it take (with the othe disks disconnected) to boot to the lock screen? Or is what you are experiencing as a delay occuring after logging in- related to startups.

Then, some have found that disk transfer rates are unaccountably very low. If so there are threads on that.

Yes, you should look to replace it soon, and ensure its state is monitored constantly. Crystal Diskinfo (free) can generate alerts against thresholds. It's still usable, but on its way out.

Have you tried booting without the other disks connected? Still a valid question.

Have a look at your Update History - your build is old- it is possible your PC is trying to update and failing. Post a screenshot.

How long does it take to boot to the lock screen?

And if you do a clean boot (Google if unsure) how long to boot to desktop, and what does your task manager show?

It's normal for there to be significant disk activity after logging in depending on what startups you have enabled.

There remains the questions of disk transfer rate of course. Sometimes people find this is very restricted - a number of such threads on this.

Hi, replacing the disk is usually easy. That and RAM are two of the easy upgrades. I don't know the model of your PC so I don't know how old it is. If it generally functions well, and replacing the disk solves problems, that would be cheaper than buying a new PC and much more environmentally friendly.

You can find youtube videos of how to replace a disk drive, perhaps even one relevant to your PC or similar.

You could consider upgrading to a SSD and benefit mostly from boot to lock screen typically in 12-13s. You'd need to check on form factor (shape) and connectivity, and decide on capacity vs price.

Disk imaging esp. over USB3 is much faster with a SSD because it's disk intensive.

What's interesting from your update history is the lack of evidence of any attempt to upgrade to 1909. I had wondered if update failures might have led to some of the disk activity. Have you ever been offered that via Windows Update?

Your boot time looks pretty good.

Your disk figures look somewhat low. Here are some to look at- the first are SSDs so ignore them- move on to SATA drives:
