Oops, forgot to mention the ‘obvious’.
Thank you for an otherwise helpful article and the commenting option; all are most helpful.
Er, sorry to be picky, but is this a typo, or have you forgotten something?
Windows 7 (extended support only): 30 vulnerabilities: 3 critical and 27 important
Windows 8.1: 37 vulnerabilities: 3 rated critical and 34 rated important
> same critical vulnerabilities as Windows 7
Windows 7: *30* vulnerabilities
Windows 8.1: *37* vulnerabilities
By my reckoning, the above indicates that seven vulnerabilities are missing from the Windows 8.1 listing! Not that the Windows 7 listing managed to show all “30 vulnerabilities”! Have I missed something?
We only link to the critical vulnerabilities.
June update took 1hr to download and 8hrs to install. After 8 hrs, there was one change. The desktop background color changed. Otherwise, all were same.
I will change background in 8 secs and 8hrs not required for this
Hello,
I had problems after updating KB4561600: impossible to open PDF files!!!
I was able to open files with other app (Adobe Touch) but not with Adobe Acrobat Reader DC.
After removing this update and installing again Adobe Acrobat Reader DC everything works!
Does anyone had the same experience?
Thanks in advance!
Windows 10 is a joke.
Good luck having a stable machine during these times when a lot of people are working from home or your job is dependent on a Windows machine.
Hate fogs the brain cells. Millions of people are fine with W10, since it works well enough for them. My anecdotal experience( worth at least as much as yours) with a handful of systems is it performs adequately, no “luck” involved.
It is perfectly legitimate for the contributor above to suggest (s)he doesn’t want to be spied on by microsoft or anyone.
When we buy products we are not agreeing to be spied upon – regardless of oceans of small print with make it legal, it is still not moral.
The Adobe update for 8.1 is 21MB. That’s amazingly large…
Sorry for unrelated note but, what’s happening with 2004? Are they delaying that until the “issues” has been fixed?
No, they just block the rollout for affected machines.
Martin,
If Microsoft knows which PCs are affected why can’t Microsoft display 2004 incompatibility cause to the users?
Because they’re Microsoft where the motto is “Let’s strive together to make sure nothing makes any sense whatsoever!”
Good question, I don’t know.
Surprised to see the biggest security threat to users’ privacy still hasn’t been patched, that being the extensive unstoppable telemetry and vast data collection by Microsoft corporation from Windows users, on full-level by default, dwarfing anything from Google or Facebook, who’s products you can choose not to use if you don’t want to, unlike Microsoft’s that came pre-installed with the computer.
Where is the outrage over microsoft’s telemetry practices?
But we raise all hell when we think china might have done a fraction of this in Huawei devices or Deepin Linux?
Getting really tired of people telling me to use Linux the moment I mention the excessive level of telemetry embedded in Windows.
I want to use Windows but my use of it is my business, I don’t want my private usage or data sent to Microsoft.
“…I don’t want my private usage or data sent to Microsoft”.
I’m the same. That’s why I still use Windows 7. I run Brave browser sandboxed using Sandboxie (the full version is now free). I’ve never updated W7 in the past year..and..touch wood..Ive never had an issue. Plus the Sandbox helps guard against Ransomware.
As Iron Heart said: There’s always Apple Mac, Linux (ahem!), or Windows 8.1 + Classic Shell combination, assuming you can find a machine running W8. (no issues there with , or with Windows 7, regarding private data sent to Microsoft).
@Carroll and Rob.G
In terms of privacy, I think this is a fairly accurate ranking:
Most Linux distros > outdated Windows versions (like XP / Vista) > Windows 7 / 8.1 = macOS >>> Windows 10.
So let’s say that Linux is not an option because of various obstacles, or missing software, and if we put aside older Windows versions for security reasons and because newer hardware doesn’t support them, then I think Windows 7 / 8.1 and macOS are the “better” options still in terms of privacy. If you read up on the many things Windows 10 collects, you will find that older versions of Windows or macOS are indeed kindergarten level compared to that. Windows 10 is collecting the most data out of any OS in existence and it’s not close.
That being said, one can improve the situation somewhat with tools like StutUp10, which is just but one of range of tools that try to silence Windows 10:

@Rob.G in particular, you mentioned that Windows 7 / 8.1 are not problematic, this is not entirely correct. Many people are unaware of the fact that Microsoft has backported some of Windows 10’s telemetry and has rolled it out to Windows 7 / 8.1 via Windows Update:
– https://www.theregister.com/2015/09/01/microsoft_backports_data_slurp_to_windows_78_via_patches/
– https://gist.github.com/xvitaly/eafa75ed2cb79b3bd4e9
But then again, they didn’t port all or even the majority of Windows 10’s telemetry back to Windows 7 / 8.1, both Win 7 / 8.1 are still kindergarten level compared to Windows 10 in terms of data collection. Plus, the related updates can be uninstalled.
Sad to see that many people are running the worst possible combination, which is Windows 10 + browsers like Chrome or Edge – this indicates a lack of interest in privacy, and gives the companies behind these products a reason to continue with or even expand on their privacy violations, much to the detriment of people who still care. I totally understand why some people can’t get around Windows in some cases (avoiding Chrome / Edge is easier, though), but one should at least try to improve privacy inside of the OS one has to use.
*ShutUp10, seems like it’s typo day today.
@Brian K.
Well, you can install Linux without having started up Windows at all, if you are already prepared, so you are not really “forced to use it”, unless you have software that only runs on Windows.
And I think that it will never be fixed since Microsoft distributed Windows 10 for free in exchange for your data, the whole Windows as a Service thing.
“Well, you can install Linux without having started up Windows at all”.
I’ve fallen for that line before. I’ve tried installing various versions of Linux on my top-end HP laptop..only to find that every version I tried made the CPU fan run non stop, and the CPU percentage to run around 65%, even on idle – yet the laptop runs fine in this respect on Windows, ticking over at 1% cpu on idle, and hardly ever hearing the fan come on.
I spent a week trying to solve this major issue with Linux via the various forums, and what I discovered was that its a very very common problem with laptop users..and there doesn’t seem to be a fix. Very complicated command-line fixes are often suggested on the Linux forums, and some of the threads are eventually marked as ‘solved’ (for some reason)… but still many people post saying its a common problem and they cannot run Linux on their laptop.
So please, when recommending Linux to Windows users, please mention this issue; ..AND the fact that its very common for Linux to mess up the boot sector when dual booting Linux with Windows…and often quite difficult to recover from.

@Rob.G
Well, that’s unfortunate. I haven’t played around with Linux enough to claim any kind of expertise in that field, I just know that it should(!) be possible to install Linux without having booted up Windows. But yeah, I’ve also heard that it can mess up boot partitions, and does so quite frequently.
As for myself, I am a Mac user and I also have a PC running Windows 8.1 + Classic Shell. I know that I will probably get some flak for saying that, but I think macOS is a pretty nice middle ground. None of the problems of Windows, while also having a decent selection of software. I really think more people should use it. I’ll now seek shelter for having claimed that macOS is any good. ;-)
“….I’ll now seek shelter for having claimed that macOS is any good”.
Ha, yes…run and hide Mac-boy! Seriously though, Macs are well made and popular (in the higher circles you obviously move in;-) I’d probably buy one myself if it wasnt for the price-tag. Even a second hand Mac-laptop will set you back around £800 here in the UK. I could buy a new HP gaming laptop for that price, and still have enough left over to buy an expensive set of headphones.
I’m with you on the Windows 8.1 + Classic Shell combination. I think W8 is underrated these days. (Never thought I’d ever say that).
All well on LTSC 1809.
Very useful, thanks !
Thanks, Martin, For explaining and guiding my update from my Windows 10 pro. o.s. to version 1909 Build 18363.90
