I certainly feel for you. Among the list of many disturbing aspects it presents - is how much of your tablet's bandwidth budget does it consume?

WIN 10 is NOT fit for purpose

That part I can't agree with from my own personal experience because it performs very well for me. Perhaps it would have been more accurate to say:

Micro$oft's policy of indiscriminate upgrading without forewarning, or without permission is unconscionable and unethical.

Among the list of many disturbing aspects it presents

Another disturbing aspect which just occurred to me is if that had happened in recent weeks to some of our final year high school students in their critical final examinations. I believe there are some subjects where the use of smart phones/tablets is not only permissible, but necessary.

I wouldn't want that episode of yours to suddenly imperil my university entrance chances. That could be catastrophic.

Particularly where entrance requirements [Australian Tertiary Admission Rank (ATAR) ] are pretty tough. For Medicine as one example, an ATAR of 99.6 might get you in the front door, while 99.5 probably wouldn't. That 0.1 difference can easily be won or lost.

Yup, Windows 10 is great for consumers but really not worth the update and hassle for enterprises.

WIN 10 is NOT fit for purpose.

European law dictates that goods must be fit for purpose when sold.

UK Citizen's Advice: unusable (‘not fit for purpose’)

It was when I bought it, now it is not plus I haven't a clue what is going on with the machine.

Last night after 3 hours and twice failing to update to Windows 10 Home, Version 1511, 10586, this morning it is again attempting to update. Nothing is happening, it is simply sitting there downloading updates 0%

This is a 32GB tablet, no photos, music nor films on it, during one of the update attempts it kindly informed me that I did not have enough space and that I had to perform a disk clean-up!

At least it is usable right now however this is a small test machine for checking sites and understanding Win10 on a tablet, nothing complicated whatsoever, heavens knows what anyone would do if this was their one and only or primary machine?

@IanCP - Schools and using technology concerns me since they are clearly not thinking things through and getting extremely bad advice. My 6 year old grand-daughter recently came home with homework to be done online however no one had thought to ask if anyone had systems that were compatible with the work to be done.

What a complete and utter horlicks!

Sure, if you had an Apple iPhone it worked, on some of them.

Android, OMG, we have 6 Android tablets none of which could do anything until I decided to try the desktop version and that worked, not even my daughter's latest Samsung Galaxy 6 would work and as for Blackberry or Win10 machines, forget it.

Needless to say next day the school was told what for by nearly every parent and the programme has been withdrawn ... Interestingly, it's Australian!

I can sympathise. A colleague was avoiding installing Win 10 on a Win 7 machine until he was ready. He's mystified why it appeared to start the upgrade. As it happens, the upgrade went smoothly and the laptop is actually working better than is did before. The upgrade session did delay any work on that machine while is processed the whole thing. He's convinced he never started the upgrade process.
On his suggestion i'm going to update the Win 7 machine here to see if I get any benefits, but i'm going to do it at my convenience, or so i believe.

Added -
My Android tablet updated itself, and it's had a number of really annoying aspects introduced since the upgrade. It appears I cannot roll back.

Microsoft is not the only one with update annoyances, imho.

So...11/2 hours later and I'm restarting it, hopefully it has achieved what it set out to do.

50 minutes for the restart/upgrade/whatever ... M$ really knows how to pi$$ me off!

It was when I bought it

Mmm... not necessarily. If you buy something expecting it to last for a year, with pricing based on this premise, and it's got a hidden feature calling on it to self-destruct after a month, it doesn't take an awfully talented lawyer to say it never was fit for sale.

After all its messing about over the last 24 hours it now seems to be working fine however the "remote" take-over of the device and its unusability for an extended period of time simply cannot be what M$ intended with this operating system surely?

I had already had similar roblems with desktops and PCs when 10 was introduced and it was precisely for this reason that I reverted the machines to 7, this is not, as nakkers says, an Enterprise OS, far, far from it.

Windows 10 works perfect on both my Acer Aspire & my Microsoft Surface tablets (as well as my desktop.) In fact, Windows10 seems to be perfect for tablets... I like it much more than iOS.

RedBar - Aren't you the one who had trouble with the Windows 10 upgrade to desktop also?

RedBar - Aren't you the one who had trouble with the Windows 10 upgrade to desktop also?

I'm beginning to believe RedBar/Micro$oft/Windows 10 are having a mutual hate-fest this year.

Hopefully 2016 will prove to be a better year for RedBar without any further hassles.

I really do hope people are electing to "custom install" rather than an "express-let me do it-M$ knows best for you" installs. [Just my opinion]

I do agree there are some negative aspects to these automatic updates of Windows 10. I just watched NVIDIA install an automatic driver update. When it was done, I found a short-cut icon on my desktop to a new 3D Vision Photo Viewer app that was not previously on my machine. Gee thanks. Now all I need are some 3D photos. Maybe they will appear with the next automatic update.

Is it possible the problem appears when the download is coming from another users system that is substandard? Was there someone at the other end of this update whose computer was not working properly because it was updating someone else's machine?

I'm beginning to believe RedBar/Micro$oft/Windows 10 are having a mutual hate-fest this year.

I feel sure that it is the age of the updating machines and there being no compatible Win10 update for that piece of kit/hardware/software/whatever.

I have nothing newer than 4 years old, I have no necessity since they are all excellent, fast PCs and latops, they do everything I need them to however each one had updation and compatibility issues, one machine went from being a nice 1920 x 1080 HD screen to 800 x 600 with no compatible driver for Win 10.

A couple of machines had stuttering issues, it would work, then the screen would flash on and off, things moved about on the screen desktop, all-in-all not a good user experience and definitely not confidence inspiring.

I have also had more than a dozen local people bring their Win 7 machines, in fact everything I have reverted has been Win 7, no Win 8.0/8.1 except for my phone, therefore this makes me believe more than ever there are more compatibility issues than anyone is daring to admit.

I did, at my own risk, convert my Lumia 1520 from 8.1 to Win 10, within a couple of weeks I had to rebuild that phone, obviously there are known risks with this since MS actually provide the tools with which to revert ... Since then my phone has performed impeccably, Win 8.1 on a phone is a superb OS for me, I have 4 Lumia Windows phones which should say something:-)

I know several people who are resisting the update from 8.1 to 10, even though they hate 8.1 at least they have it running smoothly. Several people who have bought brand new Win 10 machines are reporting everything as being fine but all have said they hate the automatic updates however one has complained of buying two "identical" Toshiba laptops for their office yet one of them cannot connect wirelessly to their printer, bizarre!

Is it Win10 or the gubbins inside the updating machine?

I actually favour the latter therefore I'll simply lock down my machines until I "need" to buy something new.

I said i'd update a Win 7 machine (earlier in the thread) to Win 10: Here's my experience on that machine.
It took about an hour in total. However, it seemed a little slow at first, but being a laptop the HD was probably spinning slower than a desktop, which made the process appear to take longer.

As far as I can tell, the system is working perfectly. No glitches, strange happenings, etc.

I do make sure that all the drivers are kept updated on all machines. Out-of-date drivers have caused some instability issues in the past, and I found it worth the effort to invest.

I recently was asked by a not-tech friend about a new desktop they wanted, and I told them to go straight to one with Win 10 already installed. I've not heard from them, so it may have been just what they wanted.

When it was done, I found a short-cut icon on my desktop to a new 3D Vision Photo Viewer app that was not previously on my machine.

<rant>One thing that really annoys me is the automatic install of bloatware, no matter what it is, and whichever software company it is, stop it, stop it, stop it. It's really annoying me. My Android phone is probably the worst for that.</rant>

Well regarding updates, I updated events in the last few days on a companion thread. I don't know if many people have read it yet,

However, there are complaints across so many threads, across many forums on the internet, going back say six months. Inter-alia, I had this to say:

Why is it interesting? Because it all comes down to a variety of different updates over the last six months for Windows 7, 8 and 10.

Probably the single most significant factor when updating systems. I've never seen issues when drivers are current.

Several people who have bought brand new Win 10 machines are reporting everything as being fine

Oh dear, I wrote too soon!

I saw my solicitor friend last night and mentioned what had happened to me and he had precisely the same happen to him on Wednesday. He does a fair amount of community work and no sooner had he started his laptop and it was taken over by M$ updates.

Like me he couldn't do a darned thing about it, in the end he lost more than 6 hours whilst the machine "did what it had to do!"

Like me he agrees that the laptop is much better and smoother now.

His partner's laptop was not connected to The Net therefore he waited until last night to connect it and, hey presto, the machine was taken over by M$. He's trying to find out if there is any way by which he can stop this happening again since, as he said "What the heck would I do if I were in Court and this happened? The Judge would go ballistic."

Ok, theoretically he could switch off his connection however what if there were a point of law that needed clarifying?

This is absolutely ridiculous, I simply cannot believe that M$ would do such a thing fully in the knowledge that it will render a machine useless whilst it performed the updates etc for several hours, we're not talking minutes, it is hours and hours.

So, the moral of this story people has to be you have been forewarned, those of you running Win 10 will soon have your machine taken over, renedered useless for several hours but at least once it has been done it is seemingly a much better OS.

I can't believe that no one else has experienced this.

Win 10 will soon have your machine taken over, renedered useless for several hours

The updates don't take over your machine and they certainly don't render it useless for several hours, not even a few minutes. I've never had an issue with just continuing to work as the updates download. Most of the time a restart is not even needed with the Windows 10 automatic updates. If a restart is needed, just save your work and restart. Windows 10 boots-up faster than any OS I've ever used, even my Linux machine.

Whatever is going on I hope you get it resolved. I invite you to consider getting a new machine, maybe a bare-bones box and load it with up-to-date software/drivers.

There is nothing wrong with my machines, this is for the completely new updated OS.

I'm not making this up, if you haven't had this update yet all I am saying is to be aware of it and for how long your machine may be out of action. Do you leave your machine switched on all the time? Maybe yours has updated without you knowing overnight.

Wikipedia has a bit more info:

November 2015 upgrade

Windows 10's November 2015 upgrade, build 10586 (also known as the "November Update", "version 1511", and "Threshold 2" (TH2)), began to be distributed via Windows Update on November 12, 2015. It contains various improvements to the operating system, its user interface, bundled services, as well as the introduction of Skype-based universal messaging apps, and the Windows Store for Business and Windows Update for Business features.[164][165][1][166][164]

On November 21, 2015, 10586 was temporarily pulled from public distribution.[167][168] The upgrade was re-instated on November 24, 2015, with Microsoft stating that the removal was due to a bug that caused privacy and data collection settings to be reset to defaults when installing the upgrade.[169]

One thing is for certain, for at least three machines that I know of, there has been a complete OS upgrade, and remember two of those machines were brand new pre-installed Win 10 laptops, therefore it is not solely me who has experienced this downtime of several hours.
