Windows 10 PC too slow on starting...

... because of housekeeping disk activity.

I have a growing problem with system drive saturation on startup (boot or from hibernation) and for up to half an hour. The C: drive is at 100% with high amounts of reads and writes from Windows Defender, Dropbox, Onedrive, Windows Update, Visual Studio, etc, etc. This slows the computer so much it can be unusable for 10 - 30 minutes. I have done what I can to mitigate it but the problem is getting worse. It has SATA 6 Gbit/s and spinning hard drives - old tech. My much newer laptop has a M.2 SSD and has no such problem.

Should I get a Sata 3 SSD as a new system drive on the PC? The PC is too old to take an M.2 SSD and I don't want to (and can't afford to) replace it yet. The question is, will the fact it is an SSD be enough to make all the background disk IO not a problem, despite it still being a Sata bus?

I'm asking for advice because I don't want to go through all the pain of sorting out a new Windows installation and find out it doesn't help. I have been assuming Windows 10 background housekeeping IO is now just too intense for 6 year old PCs, as the explanation.

The PC has 16GB RAM, and paging is disabled. I changed the swap file to somewhat bigger than it needs to be, fixed size. Then I disabled paging. I check the memory use – it is rarely more than 50%. I defrag the system drive from time to time but it is never that fragmented. I can’t image it for a quick restore as it has around 3TB of files and the SSD will be 500GB. Plus, I don’t want to replicate problems if software or installations are the cause. I have done a full surface scan with chkdsk and the disk is perfect. S.M.A.R.T. reports no issues. I’ve done all the mitigation I can think of, and that includes disabling some default Windows tasks, turning off indexing, but the number of IO demanding background processes and threads just keeps growing. I use Resource Monitor and see some processes with dozens of high disk IO threads.

Well, use something, I use CCleaner to reduce the number of programs opening at Start-up. You can delay many of them

Sam, if you'd've listened to me, you could've done that last week
