Start here:

1. Run Disk Cleanup and select all the options for cleanup. It will take a while if you have not done this.

2. Open an Admin Command Prompt and run  dism.exe /online /cleanup-image /restorehealth.

If you remain unsatisfied, run a Windows 10 Repair Install and Keep Everything.

Go to the Media Creation Link

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

how to see tree structure of all the space usage of each folder and sub folders at a glance. any good tools to show that?
JohnBusiness Consultant (Owner)Commented:
Get a copy of Tree Size Pro (Jam Software) and start with the 30 day trial. That is what I use and will show you.

Sometimes the Temporary Files folder has thousands of small files that can slow you down. Sheer size is not always an indicator. But Tree Size is a good tool.

WinDirStat is free and is also useful.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Also, if it's not running on an SSD drive,  replace it with one. You'll be glad you did.
JohnBusiness Consultant (Owner)Commented:
I agree. However I have a ThinkPad 230 with Windows 10 Insider and a 500 GB 7200-rpm hard drive. I follow my own advice above and once the machine has started it is amply fast.

do not see direct link to download and execute?
dbruntonQuid, Me Anxius Sum?  Illegitimi non carborundum.Commented:
I recommend CCleaner  Get the free version.  It's all you need.

You only need CCleaner to remove all of the temporary files,  browser histories etc and not the other functions it has.

Improving performance is a longer post but basically you increase the memory in the laptop, remove unwanted applications, remove unwanted browser extensions, check for unwanted adware/malware running, defrag the hard disk if it is a spinning hard disk and not a SSD, etc etc

Just make sure you are using the latest build of CCleaner if you elect to use it after reading this:

That version (malware) has long been removed from the Piriform web site.
gilnovSystems AdministratorCommented:
True. Piriform has cleaned the version on their site but there are other sites where the software is available that may not be the latest. Best to get it directly from Piriform. I have used CCleaner and love it.
can you tell us what model laptop it is, and what ram, cpu and disk ?
that often helps getting correct answers
you can also disable startup items, by running msconfig ( in the search window)

Download windirstat if you want to try it:

SpaceSniffer is always a great tool for finding temp and or other files that you can remove.
