Windows 10: Occasional high CPU usage on Windows 10

Thanks for the info on cleaners etc.

I've got rid of ASC since it was going to do quite a bit of changes, my windows 10 laptop is fast (i7-4510U, 8GB, 1TB Win7, 1TB Win10) so I don't need it.

I do, however, have IoBit Uninstaller, which uninstalls programs and then cleans out any leftovers from programs that haven't been completely removed. It also has the option to create a restore point before uninstalling programs. Does that do the same sort of things as the two mentioned above?

I've tried turning on the first half of the services (including all MS services), tried the second half, both successful. Tried all of the services (though had realized that somehow, some of the MS ones had unchecked). Trying all services, including all MS services, now.

Obviously we're not going to be having perfect usage; once I start enabling startup items, "sidebar.exe" (the desktop gadgets) will use about 2-3% CPU - however, I'd rather have sidebar.exe running all the time as I can quickly get a glimpse of what's happening in regards to CPU usage, RAM usage, battery meter (inc detailed information like charge/discharge rate, maximum capacity etc), CPU temperatures etc. Most of the time, I'll be idling under 10% usage; possibly under 5% usage, with CPU temps around the 30-35'C mark. What I don't want is the System Interrupts using 25%+ CPU and shooting temps into the 50's. Though having said that, even 50-60'C is an improvement on my old crappy Acer Aspire 5742, which has a well known overheating issue and often goes into the 90s when you do something intensive.

edit: Just had a look at programs and uninstalled Windows 10 Desktop Gadgets. Seems to be idling nicely for the time being, at 1% use (by Task manager). Will have to check on things, but if possible I'm not going to be without my desktop gadgets for long (they don't cause any issues on either windows 8.1 or windows 7?).

edit 2: And it's not the desktop gadgets! It just did it's CPU thing again! Time to reinstall the gadgets and see what it is...

 

Hi all,

I have decided that I need to resolve this more urgently as I need to get everything from my old laptop (Acer Aspire 5742 series) across to my Windows 10 partition as soon as possible. My Acer Aspire now can't even do a Windows Defender scan without shutting down; the overheating issue being common across the 5742 series laptops.

When I last booted up to the windows 10 partition, a few system processes such as svchost.exe refused to stop using CPU and when it did decide to start idling, the System and Compressed Memory still decided to use 25%+ CPU. Temperatures aren't a problem on this new HP laptop, however I want to get it working nicely so that it doesn't cause unnecessary heating issues.

I will go through every single process to try and find the issue; failing that, would reinstalling Windows 10 resolve the issue? Further, will a reinstall of windows 10 work nicely with my dual booting that I have set up in place, i.e. a dual boot between windows 7 and windows 10? I don't want to have to spend more money on the issue and I need to make sure that dual booting is not affected as it cost quite a bit of money to get the dual booting fixed. Also, since Windows 10 came preinstalled on the machine, how would I get the product key out?

Thank you in advance for your help!

 

Hi, from a quick scan
- your PC is fine in Safe Mode (good).
- system and compressed memory is taking far too much CPU time in normal mode.

Did you work thru the clean boot diagnostic sequence? I can't see that in the above, but may have missed it.
Clean Boot - Perform in Windows 10 to Troubleshoot Software Conflicts - Windows 10 Forums

I.e. stop added things running and see if idle CPU use is ok.

(What you lose by dual booting is your system restore points, apparently, if yuo use system restore (off by default in win 10) )

If the problem originates from an installed program, then a clean install of Win 10 would eliminate the problem, of course. On the other hand if somehow it were driver related, say, no.

Of course in Safe Mode, some drivers are not loaded, and we know it's ok in Safe Mode.
If it's ok after a clean boot, with all drivers loaded, that would be good.
