2 year old dell has really slowed down- how do i get the speed back?

Download Glarys Utilities from Glarysoft, run the automatic clean up...

@anon125 ...... sometimes a good deep cleaning may improve your performance ! If you would like i can do that with by having you run some programs for me !
These are a few to get you started !
Download these 2 programs & run them, when done post the logs so we can see if that problem goes away or do i need to have you run a more stronger program ??

Please download AdwCleaner and save it to your Desktop
* Close all open programs and browsers

*** Post that log back here or just tell me what it found ?
If it is to long then you will have to zip it or find a site to download it to & let me know where !

Post the logs so i can read them unless nothing is found ! If they are to big then zip them up & give me a link !!

Thanks !

The PC seems to be a Dell XPS 8940 tower.

Start by uninstalling the trial software you presumably don't want. Make sure you use the separate manual uninstall tool as well.

Basic question: is your ONLY problem the slow boot - or is it also slow in normal use?

Please state how long it takes from a cold boot to the lock screen
Your system disk is presumably a SSD

Note that in some cases a slow boot can result from an accumulation of temporary files, but there are other reasons too of course.

Also please as a matter of routine check your disk(s) - Hard Disk Sentinel is excellent (for SSDs too) - just run it, green is good.
Read the helpful comment for each disk.

If normal performance is slow, then
- boot and log in as normal

Wait 3 mins.
Capture 1 or more screenshots of your task manager showing resource usage.
Organise columns of high usage high to low by clicking on the column header.
Post the screenshots thus:

Tutorial available if needed.

I know that you gave us the hardware specs on the first post.
Please edit your profile with ALL your hardware specs. It will help us to help you
System Specs - Fill in at Ten Forums

Open Task Manager (CTRL+Shift+Esc) and look the applications you have on start up.

Thank you for your reply.

Await reply to my post.

Open a CMD window as administrator and type:
chkdsk c: /f
It will say your disk is in use and ask if you want to schedule to next start = yes
Restart

Back to Windows, open a CMD window as administrator and type:
sfc /scannow

If it finds any corrupted files, fixing or not, reboot and run again

Then run
Dism /Online /Cleanup-Image /ScanHealth
and
Dism /Online /Cleanup-Image /RestoreHealth

Perform a clean boot. Does it run better?

@anon125 ............... you will never know if i could find something for an hour of your time ! Good Luck ................... I'm out ...
