No reason not to be on W10 now for most people.
If you are paranoid about privacy, there are lots of tweakers for win10 to stop it "phoning home"

Do ya research. I bought a laptop last year with windows 7.

COLD Windows 10 :disappointed:

No stock anywhere!

A noticeable difference yes, but difficult to predict exactly. They are great on budget/older laptops. And Windows10 startup is quick anyway (due to startup from hibernated state); I'd predict a RESTART (which actually does a full shutdown and startup) reduced by at least 50% Others may chip in...

Anyway, a couple of checks before spending any money. 1. check it has a DVD drive. 2. check it has a standard HDD (may seem stupid but HP are putting SSDs - in M.2 format - into mid-range laptops).
Spec sheet for Pavilion 15-au193sa is here.

3. buy a DVD caddy; search Amazon for "caddy 12.7mm" and you'll find lots; ** double check laptop DVD depth; most are 12.7mm but slimline ones can be 7mm **

4. buy a SSD; you have 2 options now.
A. replace existing HDD with SSD and clean install with Windows10; licensing is done automatically and many people prefer a clean build; do whatever you want with the HDD e.g. add to DVD caddy or external caddy (HDD can be kept as is and would be a useful backup) or can be cleaned;
B. put in DVD caddy OR attach to computer via external caddy or USB/SATA lead; image C: to new SSD (although the HDD is way bigger than the SSD the C: partition will easily fit on the SSD); need to click box to make the SSD "bootable" - this option varies depending on imaging software that you use; finally swap HDD for SSD.

Does this mean i can replace the DVD drive with a 128 ssd, in addition to the 1T hard drive already in place? Will it require OS reinstallation, or just remap the hard drive partition? Will the additional of 128ssd actually make hudg difference to hard drive writing speed, e.g. booting time? Thanks mate!

Thank you for sending me that link, you've opened my eyes- I think I'll wait for a good deal on an i5 or an i7 :smiley:

Thanks for replying, you have completely changed my mind about getting the yoga 900S! PC world told me that the m processors were just as fast as i7s and that I would be better getting an m one but I'm glad I was hesitant- my old laptop was so slow and the touch screen was laggy and constantly had to be re started during the day so if I'm going to spend that much money I want it to be as fast and smooth as possible :smiley:

Ooh didn't know they had a 10% off code! Heat! I was going to get the Lenovo yoga 900 which is i7 but PC world don't have it but they do have the 900s which is just 999g but my question is- is a m7-6Y75 Processor good or is it crap compared to an i5 or an i7? It's all so confusing! I know it's expensive at £999.95 or like £899 with the 10% code but I'm willing to pay that amount for a light fast laptop- if a m7 processor is good that is. I'm getting desperate because my laptop died 2 weeks ago and I'm lost without one :disappointed:

Just sold my old 3 year old Z500 i7 3632qm, was still going strong but needed a better screen and couldn't bring myself to buy one of these new I7 processors, which lets face it are pretty crap. So bought a thinkpad W540 instead, will arrive tomorrow.

Typical oos goose chase from PC world

I am thinking to get MS Surface Pro too, because of pen and portability for editing pictures. I don't like touch pad for laptop, of course You can use graphic tablet like I am using on my desktop. Then question, why You would need laptop. If You don't have any PC for editing, different question. Also I think now is bad time to buy MS Surface Pro, as soon will be some new launches, so prices of current line should drop!

They're not really comparable products. One is an ultraportable tablet and this deal is for a full size, desktop replacement laptop.
If you don't know which one to buy, you should really start by thinking about the use cases you have for a laptop to figure out which suits your needs better.

Should I get a surface pro 4 which I've wanted for a while the i5 version for £650 or this? All advice is appreciated (:

​Yup I retired my i7 3632QM laptop last year and it was still incredibly powerful, with proper quad cores not these fake power efficient i7s

OOS wherever I look. Any ideas where I can find one.

I think I agree; £40 max for an SSD and £10 max for a caddy (to replace DVD drive); and a doddle to image the existing C: to SSD (or clean install if you prefer).
But I probably wouldn't spend £500 on a laptop in the first place :-)

Slower processor, and smaller (but faster) storage. I would go for PCworld's offer and get an additional 128 ssd and put the 2TB hdd in place of cd rom. Even this i7 is no where close compared to my 5yr old i7 (3630QM).

Compare to this at the HP store...
£500 @HP 256GB SSD rather than HDD and i5-7200U rather than i7 ** and voucher CQ117HPAF84 will give £10 off **
