WD40 is petroleum based, it is not meant for electronics, it will eat the components. I use a product called Deoxit for cleaning electronics.
Also, you know I love cats, even ones with silly human mouth faces gets a laugh out of me with all that fur sticking out lol! 
@StarTreker, Today i installed Pop! OS 21.04 on the same drive as where Zorin was installed on. I can tell you that Zorin is the problem with booting. Pop! OS boots as fast as on the external drive.
Again...using the same SSD (Western Digital Blue 1TB) as where zorin WAS installed on.
I am glad that POP OS is finally getting credit from someone for something, faster boot times. If POP OS runs smoothly for you Michel, then it will be time to customize it.
You can get themes for it from Gnome-Look.
And Bourne, I'll be a bit surprised if you don't hate MX Linux just for the layout alone. But maybe you will like that sort of thing. I've seen screenshots of MX-Linux, and I am not impressed lol.
POP OS is very popular. 
on raspberry pi 4 also pop os.
Yup, i read that too today about the raspberry pi. @StarTreker was right that pop os is good for gaming. I love that distro.
Yes. I saw that this is like "empty linux" - configurable - like "a man without a clothes example android"?
Do you want sayed to me i must tried POP OS?
Linus Tech Tips also recommended POP OS.
If they are focus on distribution what they are created then it could be mostly stable and security linux from all distributions.
Pop OS has a nice upgrade feature. So in fact if you install pop you dont have to reinstall anymore. So in fact you have a sort LTS because of that
Yep, one of the largest benefits to using POP OS, is its easy upgrade feature, and the fact it comes with the OS recovery partition, in which you can update several times a month infact. But since the recovery partition is over 2GB worth, I recommend going easy on your data bandwidth and just running that once or twice a month.

There is a big difference between Rolling Distro and LTS distro.
LTS provides well tested stability. Rolling... Does not. Rolling will show you the Latest builds... and cause a lot of headaches.
Rolling Distros are great for people that enjoy reporting bugs and helping developers identify problems. Not so great for users that expect to boot up their machine and get to work without distracting problems.
POP OS is like a sin don't get him on PC?
What?
What is so sinful about POP OS?
POP OS is literally one of the best Linux distro's in the freaking world right now.
I consider POP OS just as good as Zorin OS. I don't see how running POP OS is a sin.
But you know what is a sin? Continuing to run Windows 10, or upgrading to Windows 11, when you know full well how evil it is, but continue using Windows anyways. That is a sin.
And no, I won't let you forget it. LOL!
I know the difference, but i only said it is a sort of lts is because it can upgrade without reinstalling. Also a rolling release distro does not mean some things dont work, as i see alot of reports on issues with the zorin os lts. So what is the difference in the end ?
Do you really think Pop! OS made by System76 is going to risk a cráppy os for their machines and not test stuff ? It's a company selling computers, laptops etc.
I have bad experience with w10 and so on - my pc is to old for 10 or 11.
When I saw a software talking to me what I can and what I can't do that. Then some children windows operating system don't tell me adult and learning what i can and what i can't do that.
With linux i have good experience. POP OS is on Ubuntu but MX Linux is on Debian.
The one what I can sayed POP OS is diffrent from another linux distributions. @Michel wrote trying Mint but I saw him and Mint not evolve. I really tested many distributions.
ZorinGroup could creating two type groups operative systems. First with generation and politics to "near a windows" with some gui interface. Could be also second type with "fresh linux" - without many beautifull things.
ZorinGroup could gived a clients a choose design near a windows for newbie users or linux Zorin for people who can using only linux.
I dont because Pop! OS has much better boot time then zorin has. Also Pop! OS feels more stable for me. Zorin is stable too, but not as stable as Pop! OS
In my mind with thousand distributions people searching always something new. POP OS they have a team more people. In Zorin we have only two brothers. That makes diffrents. Diffrents people many ideas and designs. Zorin created good job because version 16 working without problems on my PC.
POP OS is like a skeleton shell Linux that what gived people chance to more configurable and probably that why is faster.
POP OS is young but they have:
You clearly didn't test pop os, Zorin has a app that can change the looks to windows / apple. You really think this can't be done in pop os ? it's not a empty skeleton. Also Pop! OS does not install to much pre-installed apps out of the box. Zorin OS does unless you untick the extra's in the setup. Pop! OS has a upgrade/restore feature, where is it in Zorin ??? i would have expected this in the Pro version.
Back to the original thread:
The boot time in zorin should be fixed, play both movies at once here on the forum. Pop! OS is installed on the same SSD drive as Zorin was.
Zorin OS 16:
Pop! OS 21.04:
If someone fully uses POP OS, they will understand my statement, like Michel does...
I Have Spoken
I am agree with that if someone from you remember what I wrote and I always tried remember some dialogs example @StarTreker @Michel and another people in forum chat Zorin. Then you noticed i tried POP OS but i have some problems.
That why I am staying on Zorin.
Maybe in future i will trying POP OS.
