Title: Nine hidden features in Windows 8.1
Post by: eye30 on March 24, 2014, 14:30:20
 Windows 8.1, which is a free download for Windows 8 users from the Windows Store, retains the split-personality Start screen and Desktop, but a host of changes throughout make both modes much more user friendly.

Here’s a run-down of the less obvious - but no less welcome - new features.

I don't care how many dot releases and changes they make, Windows 8 is still rubbish.

Win 8 and 8.1 are stable and faster than previous versions. However, the tactical changes that were made to the interface are so confusing that any gains made through a more efficient operating system are far out weighed by the time spent trying tho find your way around it.

Makes a lot of users seriously consider moving plate forms to iMac.

I have used every version of Windows since 1985 with Windows 1.01 when I used my first PC when working in Bahrain.
Since then my Windows history has been :-
1987 Windows 2 - looked after by my company's IT department
1991 Windows 3 - same
1996 Windows 95 - same
1999 Windows 98 - Now retired and having to fend for myself - I start the learning curve
2000 Windows 2000
2001 Windows ME - An utterly frustrating O.S  I learned a lot with this abomination
2002 Windows XP
2007 Windows Vista Another flawed O.S with frustrating stability issues.
2010 Windows 7 A great O.S  Fast and stable
2012 Windows 8 A faster O.S and even more robust but the Metro interface is horrid. I installed Stardock desktop so it replicated Windos 7
2013 Windows 8.1  More speed and great stability. But I have retained the Stardock desktop because the Windows start button and desktop is limited.

During this time I once had a go with Linux but got fed up with having to mess around with it to be able to use all my software and peripherals.  I never did get it to work with my Garmin software and my phones - so I binned it. It is an O.S for a dedicated hobbyist and all I want to be is an untroubled user.

I am happy with Windows 8.1 - and sometimes wonder what all the fuss is about. If you look on the various Windows forums they are drying up because people have less problems to post and whinge about with the new system - other than those who try and use the Metro interface and incompatible software in touch screen mode.

Win 8.1 seems great, if you configure it correctly. I have mine booting straight to the desktop without prompting me for a microsoft account or any of that rubbish.

12 seconds from hitting the power-on to getting my desktop on view and usable, and that's with a standard 5400rpm sata drive (new HP laptop with twin 4-core A10 processors and 8gb ram).

Is that hard to set up, Steve.
Will have a new laptop tomorrow for Claire (No. Not in exchange for).
I'm really gonna have to make it as much like XP as possible for her - at least for a while.

This is as good a place to document the last 2 days or so.
Bought an HP laptop.
2.3GHz
4 GB RAM
500 GB HD (5400 IIRC).
Windows 8.1  :evil: :evil: :evil:

So, I set out to try to understand what was happening as it came. Disn't want to screw up anything making changes too early.
Most important things were.

Get the mail client working as close to Windows Live Mail as possible. And link Claire's existing 2 e-mail addresses. Google is your friend - but still took some doing and interpreting the various guides, then modifying accordingly.

Get rid of any unnecessary apps and place those we kept into a workable order. Learn how to relocate and resize. :p

Set up Skype and Firefox and import bookmarks.

Made good use of Dazz's Windows 8 Tips (many thanks Dazz  :goodjob: :goodjob2:)

Finally, went to download that little program  Alan Ho uses to change the appearance of the start screen.
They wanted to charge me for it so I fished around and went with Classic Shell which is free and seems to do everything I wanted it to. Spent some time adding and removing the links I wanted off the Start Menu.  Looking pretty good ATM.

Most important thing has been to find a simple version of Solitaire. :whistler:  I've got one but it's not completely the same as that in WXP. It seems to have automated some of the moves whereas Claire preferred to carry them out herself. Work in progress. :Shocked:

NOW!
The big next step.

Edumacate the regular user. :scared:

I'll update here as the progress unfolds.

Looks like the Boot SSD drive in my my desktop PC is playing up  :undecided:

Can boot from the original HDD drive but majorly out of date (and much slower)

Got some work to do over the weekend  :Pout:

But you would have had a longer life form a conventional HD.

Apart from speed, SSD's don't seem very reliable. The memory in SSD's & USB has a finite life and although tested over 1Meg cycles, could it be that certain areas are unreliable in the present SSD. What are you going to do with it, can they be tested and fixed  :question:

For the money, they are still too expensive / GB IMO.

Samsung make very good SSD's. In fact, they have some very decent performers vs cost. I have a 256GB one in my iMac. IIRC the 1TB module in my MBPr is also Samsung.

Lifespan of an SSD is definitely a concern if you have a drive that doesn't have TRIM & wear levelling.
That said, there are certain models that experience certain problems. The OCZ Vortex 2 units are well known to have issues with no longer being detected by the OS; this was caused by the controller, not the actual memory chips.
 

http://techreport.com/review/24841/introducing-the-ssd-endurance-experiment is a great read.

All that said, if you don't have a good backup plan & you're not following it… Well, silly you.

As far as $/MB goes, yes, they are still expensive, especially past the 256GB line, but you're not buying space, you're buying speed, and for the speed you can get out of them, especially PCIe SSD's, they're worth it.

I made the switch on all my hardware last year. Whenever I have to work on any machines that have spindles, I wonder why the computer is so slow, then remember it has a spindle drive in it.

During this time I once had a go with Linux but got fed up with having to mess around with it to be able to use all my software and peripherals.  I never did get it to work with my Garmin software and my phones - so I binned it. It is an O.S for a dedicated hobbyist and all I want to be is an untroubled user.


Linux, is trouble free and just works and is quite customisable for those that feel so inclined. By way of example, the Apple OS has a Linux core and is regarded a stable easy to use desktop environment. Linux will remain relegated behind MS and Mac OSes simple because if you buy a PC you get windows by default and if you buy a Mac, well you get what they give you.

If on the other hand you are running a server Linux is the king unless of course you must have to integrate into an MS environment (AD) run Sharepoint, SQL server or such. Much of the web is driven by the LAMP stack (http://en.wikipedia.org/wiki/LAMP_%28software_bundle%29) including almost certainly this web site.

In addition many appliances are using Linux including most likely your home router. So its out there but sadly not getting the respect it deserves on the desktop.

The reason it might be considered an enthusiasts solution is because of the lack of driver support by peripheral makers such as Garmin for example. Its likely that drivers exist or you can roll your own but its unlikely a linux version of the supporting application software exist. And that's a shame really.

I think Its well worth taking another look if you have not done so for some time as its a very solid mature desktop environment these days. Suggest Debian or Centos and grab some old PC like a mainstream Dell of some sort, pop a hard drive tray  (http://www.techbuy.com.au/searchcat/HDD_DRIVE_BAYS.asp)in it, grab a couple of drives so you can try different variants and have fun.

As an addendum to Alan's chronology:

No call for a HDD tray when PenDriveLinux (http://www.pendrivelinux.com/) will boot and run entirely in RAM off a USB. :victory:

If after making comparisons you then want to grow your system into something more substantial, by all means. :goodjob:

Thanks AK & PP  :goodjob:

I love SSD drives (currently posting this on my main PC ) I have it working on the original 1TB standard HDD what a slug!  :fum:

Fortunately I back up all my files regularly to a 1TB internal drive and my NAS drive as well so if I cant recover the info off the Vertex SSD no big drama as all the programs loaded on there can be reloaded very quickly on the new Samsung when it arrives.

THAT is the other thing PHIL  :winker: (loading programs including a clean install of Win 7 on to an SSD is lightening fast compared to a conventional drive - up to 4 times faster from my experience!) :happydance:

Sounds like I might still be able to clone the Vortex drive anyway if it is just a detection thing by the OS. My first SSD (a Kingston V100 lasted about 12 months then did the same thing) I have been using it as a small Music Storage drive in this computer and it works fine for that!

Since you are using a vintage PC with the performance of a slug I have typed this message slowly so you will be able to read it.

I tried a 128 GB SSD in my PC about 18 months ago - it went tits up in just over 3 months. I was offered a replacement but I decided to a credit against a 1TB hard drive.

I will wait until I upgrade the PC with a new motherboard and processor before I try an SSD again. What I have, with Windows 8.1 properly configured,  is quite fast enough for my purposes at present so there is no rush.

Post by: Aussie Keith on March 29, 2014, 02:54:07
Turns out 128G is too small and really the only thing on your SSD should be the OS and apps. Data should be elsewhere on a regular drive.  In the past it has been observed that if there is insufficient space on the SSD, which is to say more than about 80% full, they will not go the distance.

I only ever put the OS and programs on the C drive - which currently holds 86 GB. A 128 GB SSD should have been plenty big enough.

My data is on a 1TB D drive. Currently 282 GB

My wife's data is on a 1TB E drive. Currently 123 GB

Internal 2 TB drive F - used for weekly Acronis back ups of C drive and daily Second Copy back ups of D and E drives onto 2 TB disc

External eSATA removable disc drive - using 2 TB SATA discs for weekly Acronis and daily Second Copy duplicate back ups. A second disc duplicates the files monthly for storage 50 yards away in my garage.

Hence I have 3 copies of all backups with one being stored remote from the house. My back-up routine is thus belt, braces and a piece of string.

I have got so used to the reliability of Acronis C drive images that if the OS or a program gets grumpy - I don't waste time fiddling with it - I just restore the C drive. It takes about 25 minutes.

:undecided: It's a couple of years old, but an i5 with 8gb of Ram. I only load programs I use on the boot drive so the 128SSD was never much more than half full.

I love the responsiveness of SSD. My laptop is about 18 months old and the SSD drive in that (only 128gb) is still going fine :fingers: I save everything to SD card and also to my NAS drive.

I use True Image 2014. It seems to be 2010 with a modified interface to simplify the operations.  More user friendly except for an annoying auto file name habit. It's not easy to force it to use a manually entered file name.

Trev, if you decide you do want something a bit faster and don't want to spend a fortune, these are a cheap option and while nowhere near as fast as an ssd they are quite a bit faster than your standard run of the mill hard drive...

Thanks Rusty. I'm not likely to anytime soon though. I use my computer for e-mail, storing and processing photos, web surfing and Word and Excel (with occasional Powerpoint stuff) and watching some catchup TV.
The only time speed catches me out is on some HD Youtube vids but I that would be web access (ADSL1) rather than anything in the computer.

The tech is much improved over the first gen, far more reliable these days. I have had ssd's running in both the htpc and a routerboth running 24/7 for well over 2 years now with no issues. And yet I know they fall over quickly if too small a device is used which is likely the case when they were small and expensive.

I thought the benefit of SSD was that defrag is unnecessary and allocation of data over the many sectors was a non physical thing, therefore more reliable.

As some of you know, I am a keen PWS (Private Weather Station) enthusiast and have my own weather station running Cumulus which collects data and uploads it to a website.

Well, there is quite a bit of discussion on the Cumulus forum about Win 8.  Just today I read with interest this piece of info about an upgrade coming soon to Windows 8:

Breaking news (via Windows Secrets newsletter of 27 march 2014);
Major update for Windows 8.1 coming soon
At next week's Build 2014 developers' conference in San Francisco, Microsoft will reportedly release its update to Windows 8.1. Apparently, Windows 8.1.1 (as it's unofficially called) will arrive via Windows Update and not the Windows Store. (Windows 8.1 could be downloaded only from the Store.)
Based on previews, the update will be smarter about the type of computer it's on. It'll boot directly to the Desktop on those computers that don't have touch screens.

Consumer class SSD's fail mostly due to faults in their controllers.
Enterprise class SSD's in high write environments can fail due to high number of write cycles.

However if the SSD is from the very early generations, they can fail due to reaching the write life cycle of the memory chip.

Modern SSD's mitigate this by using TRIM, where the OS tells the SSD controller which blocks of data are no longer used, and can therefore be deleted.

SSD's also use wear levelling, where an SSD uses additional unadvertised space on the drive to ensure that the write cycles are spread evenly across the memory chips so as not to excessively write data to particular cells, and therefore wear that memory cell out prematurely.
For instance, a 256GB SSD may actually have another 20GB of space that is only available to the SSD controller.

The very interesting thing about modern SSD's is that data, once deleted, is gone for good. It is no longer retrievable. This video from Defcon 21 is a great watch, explaining why/how in more detail.

Also, just to clarify, Mac OS X is not built on Linux, rather it inherits genes from BSD, and NeXT OS.

Also, just to clarify, Mac OS X is not built on Linux, rather it inherits genes from BSD, and NeXT OS.

Excellent explanation. This was the subject of much discussion on the untangle forums a while back when there was a spate of ssd failures in untangle appliances. The common factor was small capacity and lots of writes. In nearly every case, they were subject to controller failure.

In our Riverbed fleet the larger devices have banks of ssd's and I am yet to see a fault. They handle massive volumes of data. On the other hand we routinely swap out regular hard drives owing to disk faults. I am not sure what conclusion to draw from this and as I said my own ssd experience including two machines running 24/7 for years including the router which is constantly logging data has been exemplary.

Here is an interesting article:

The proper care and feeding of SSD storage | PCWorld (http://www.pcworld.com/article/2038511/the-care-and-feeding-of-ssds-what-makes-these-speedy-drives-hum.html)

From which this snippet of hope:

That 'dead' drive may just be awaiting rescue

How is this possible? Many times, what seems like a hardware failure is actually a firmware failure. The controller simply encounters a situation it can't deal with, and locks up.

So maybe a firmware update can resurrect your "dead" drive. Of course, if its not communicating how to flash it?

That's a great article there Keith. Has a nice straightforward explanation of how SSD's work.

My experience with SSD's has also been positive, however I have never filled one beyond 50% capacity, and never use it for anything more than my OS and temporary data storage. I do use it for my VM's, as I need the speed for them to be worthwhile running, but I'm never without a backup of anything critical.

This is as good a place to document the last 2 days or so.
Bought an HP laptop.
2.3GHz
4 GB RAM
500 GB HD (5400 IIRC).
Windows 8.1  :evil: :evil: :evil:

So, I set out to try to understand what was happening as it came. Disn't want to screw up anything making changes too early.
Most important things were.

Get the mail client working as close to Windows Live Mail as possible. And link Claire's existing 2 e-mail addresses. Google is your friend - but still took some doing and interpreting the various guides, then modifying accordingly.

Get rid of any unnecessary apps and place those we kept into a workable order. Learn how to relocate and resize. :p

Set up Skype and Firefox and import bookmarks.

Made good use of Dazz's Windows 8 Tips (many thanks Dazz  :goodjob: :goodjob2:)

Finally, went to download that little program  Alan Ho uses to change the appearance of the start screen.
They wanted to charge me for it so I fished around and went with Classic Shell which is free and seems to do everything I wanted it to. Spent some time adding and removing the links I wanted off the Start Menu.  Looking pretty good ATM.

Most important thing has been to find a simple version of Solitaire. :whistler:  I've got one but it's not completely the same as that in WXP. It seems to have automated some of the moves whereas Claire preferred to carry them out herself. Work in progress. :Shocked:

NOW!
The big next step.

Edumacate the regular user. :scared:

I'll update here as the progress unfolds.
Today was the first lesson.
Went better than I'd hoped for.
Claire is very intelligent and picks things up quickly but she has developed a bit of a phobia about computers and technology - more on the basis of she doesn't need it than she can't do it.

And most importantly, I worked out how to copy the old, original W/XP Solitaire into W8, so it runs off the desktop.
Only real problem ATM is I still haven't got it right as far as accessing her iinet e-mail through Windows Mail (8.1). It recognises the e-mail address but isn't downloading the messages.

Sorted the email issue.  :victory:
