Trying to figure specifically what's slowed down a laptop, but I guess it's a general question

windows 10 pro laptop, joined to a domain, but off the network for months now.

it's an i5 and 8GB ram, 320 GB 720RPM hard drive with about 100GB of data (so there's space on the hard drive).

I ran crystal disk info and it says the drive is physically OK.

Ran disk cleanup, removed old system files
Ran ccleaner for disk cleanup and registry clean up

But overall, the computer is sluggish  and will take upwards of 7 minutes to restart (keeps saying restarting'.  Although repeated restarts, the time does drop to 3 minutes or so.

It did have bitlocker turned on and it was running OK.  Then I wanted to put in an SSD and read you should turn off bitlocker.  started that and also ran the windows native disk cleanup... it was deleting files while also decrypting.  then it froze / I let it sit for hours.... black screen / woudln't wake up.

Turned off by pressing power button, then turned back on.  I think this is when it got sluggish.

I turned on bitlocker, it encrypted, then I turned off bitlocker / it decrypted...  still sluggish, especially at restart.

I cloned the drive to an SSD and it runs nice and fast.  So the software isn't corrupted - it cloned a fast experience.  

What about cloning back to the regular hard drive.  Might speed up the experience on the old drive?

I also ran wise registry cleanup.  the rotating hard drive was still slow opening apps, restarting,etc.

But in general, what are some things you do to keep a windows pc working good?  i5 and 8gb of ram is a nice config, right?  Only 1 1/2 year old machine.
