Windows 10 / 11 post WU installation cleanup script

I don't think browser tabs open have anything to do with the processor usage unless there's something like a continuous script running on them. Here's mine with ten Firefox tabs open sitting on static pages. It was at 2% before I hit the screen capture button.

Ofcourse it does, Chrome is very demanding on memory and everything else. This goes jumps anywhere from 27% to 103%.

And this is only the Chrome Beta side.

This is the Chrome Dev side.


See https://support.google.com/chrome/thread/60223994/constant-high-cpu-usage for a better explanation. Each tab is a separate chrome.exe process so one tab can crash and it won't effect the others, atleast that's what Google claims.

Sort of.

If you look at this, it makes it (more) clear it is referring to used because it also shows the total and then the percentage:

Red points to used and Green points to total

Or even more so in my own:

But I should have realized it didn't write the word used but meant it anyway lol - it's been a while since I used PH....

As for the laptop and increased CPU usage, you'll probably have a lot of other things that are laptop specific too that I don't have on my home built desktop, so I can allow for a 48% CPU load at any given time, I know I've seen similar in the past on older laptops I've owned, too.



None needed, the topic is fascinating in and of itself, and the thread has maxed itself on content as the script is not being developed any further, and alternatives are also now mentioned.



Which, for all intents and purposes, any web page that displays dynamic advertising will, in fact, contain. So, there is that.

And corporate private pages (for employee use) can be notorious for connection monitoring and aggressive (generally accepted) threat alleviation and prevention, too, so...




I'm not 100% convinced, even with my explanation above of dynamic advertising being an actively running script in any given browser tab.

I think the real thing missed is that laptops also have a ton more CPU scheduling and active throttling going on by default, not to mention a ton of 'utilities' that run in the background, like active software for thermal mgmt, trackpad monitoring, hotkey monitoring, and more. That, coupled with what I can see in the screenshot that you posted in reply to me earlier, from System Informer, shows a few apps running like acrotray, monitoring for use of acrobat, The Adobe CollabSync, monitoring for file generation to sync with their servers, if memory serves me correctly, Alexa, which will be monitoring for voice instructions, BitWarden (normal AV, any AV on a machine will have active processes for real time protection so cannot really be concerned about this one), Anydesk, monitoring for remote connections, etc....

There is a lot running there and that is just the first two letters of the alphabet lol.

I bet if you close your browser completely, you'll barely save 5% of your CPU usage, those are more than likely not the actual culprit here. The 'culrpit' is going to be the sum, the amalgamation of everything running - aka death by 1000 cuts.

Remember you are looking at the bigger more detailed information just like if you look at what I showed in post #95, I can also show the System Information which also works the same way as Task Manager, it's more of how each thing presents it, and why would it matter because it already shows you the total percentage anyways and it's not that hard to add 2 numbers together as the % obviously will add up to 100%. Ofcourse the more detailed will show memory which is Physical + Swap added together but the right still tells you it's 64GB installed. 32GB is officially supported by Dell since 64GB memory was not available when the machine was originally introduced so anything more than 32GB is not supported and in fact, other than memory bought from Dell, it's not supported as many people bought Crucial and other brands only that they didn't work and Dell's official answer is their engineering does not support non-Dell purchased memory when people had problems. It's in this thread and Dell's official answer from engineering about using memory not bought from Dell:




Yes, remember a laptop is limited in air flow by design among other things and this one happens to have the CPU and GPU mounted on the side facing the table and not the facing up to the keyboard so it makes it a lot harder for the heat to escape.

As for closing the browser, give me a few minutes since the beauty of Process Hacker/System Informer is that I can kill/restart more than one process at a time. You already see what it uses above with the browsers running. Let's see what it shows after the chrome.exe processes are killed.

Usually, laptops comes with third party software but Microsoft Signature Edition which is hardware sold by Microsoft Store online and their stores after learning what it meant was it didn't come with anything other than the OS itself which is true because I don't have anything other than the drivers on top of the OS. Acrobat and acrotray are stuff I added recently. Same with the other stuff you mentioned, those are all stuff I added.

I forgot to screenshot the # of processes for before but the after is 518 processes with chrome.exe not running and this is the result without the browser running, the CPU% went as low as 16%:

Notice the big difference for both the CPU and Memory with Chrome closed. I did not mention that I have atleadt 5 gmail.com sessions running to different accounts and those are major resource hogs. For my main account, I have a extra one running so I can read the current days email in the main one and the extra one is to go back to the 1,000 messages per day for the last 40 days which also adds to it.

I should mention that even though I do not have MS Edge opened, there are many instances of 48 msedgewebview2.exe processes and 18 msedge.exe processes running in the background.

So atleast this proves the browser does use both CPU and Memory big time. Even based on screenshots alone as it's hard to capture the low numbers without doing a video capture and that drives the CPU up higher. But the CPU basically went down 72% and the memory usage went down 40.4GB.

A lot of the CPU is also taken up by SystemInformer which I have always running since it's handy when I need it and I like looking at it from time to time.

The number of browser tabs open increasing processor usage sure isn't universal as I opened ten and it didn't change my usage at all. I agree that if there is active content continually running as a result of opening that page, that's something else.

You also don't open gmail that has 1M+ messages for each process among other things. Yes, you can open 10 but it depends what you are running in the browser tabs. A lot has to do with Chrome requiring extensions to work a certain way. Before, I had a extension that suspended all tabs that were idle after awhile so the CPU % was way lower. It was called Great Suspender but becuase it didn't meet Chrome's new extension requirements, I can no longer use it. Try opening gmail even in one tab and then scroll through 10 pages of 100 messages per page or open Facebook in tabs and then scroll through about 10-20 pages. Both are resource hogs as I might start with 70 in Chrome Beta for example but for like 10 minutes, I can have another 20 tabs, one for each notification in Facebook alone since I don't want to view and then back, open notification again and view and keep repeating so I will have 90 and then spend a few minutes on each tab and then close it after I am done.


as a example. I have over 10 elevenforum tabs opened because there are somethings I haven't done yet which are part of the 70. I have another 20 Amazon.com tabs opened for different items I still need to look through later.

This happened just now on Chrome for Applying Loctite on laptop screws - Page 2 - Internal Hardware
so Chrome apparently thinks this page is a resource hog...

Which is exactly what I said in the previous post.

Except you said active content, a forum thread like this with 5 messages displayed should not be a resource hog which Chrome apparently thinks it is.

I have 20 posts per page and this is page 6 of the this thread with exactly 5 messages shown for page 6 and take a look at the resources it is taking:

283MB and 32.5% CPU.

By comparison, the Gmail tab which has the notification e-mail for your post above takes 1.7GB and 0.1% CPU and I can understand the memory being bigger because it is displaying 100 emails per page:


Turn on the task manager in the browser and watch how it changes even with 10 tabs of www.google.com over a longer time period. It will not take much resources when you first launch the browser but it will gradually take up more depending how long the browser process is actually running.

It does matter though because even in the Windows XP/2000 days, there are many people who open a lot of tabs and unless the following is edited in the registry, the system will run out of resources:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows
Windows SharedSection=
which can have a maximum of 48MB combined.
and then there is for Windows 10/11:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota
which maxes out at 64MB

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota
which maxes out at 17.5MB

With the new motherboard, I did not do the above yet and I do run out of resources after a few days. With the old motherboard, unless I do the above, it will only take hours before the system is extremely sluggish.

Those limits are the maximum allowed to be set regardless of the amount of memory one has.

Windows itself has always been poor at managing resources regardless how much memory one has. The only reason I even use it is because of the software available for it, not because of the quality of the OS.

But if you don't know that there is a difference, then you won't realize the mistake.

I'm done arguing about this - the value as I already acknowledged is showing used, and I've used the same software in the past.

Yes, you have a valid point since it's similar if one actually used that product or not to realize it. System Informer supposedly is after someone else took over the project and the name change had something to do with Microsoft keep flagging it as something bad... I guess the H word isn't exactly something good to use.
