They mean if you choose to use Windows 7 on it instead of 8.1 (or the newer 10). Depending on your needs, you may opt for one version or another. For example, in my regular business needs, I need a lot of software that I KNOW works on Win7, so if I need a business laptop, I'll choose that. On the other hand, if it's a personal computer, I'll probably choose the latest and greatest.
Windows version and the final notebook product item number are a few things that you would be using to find hardware or drivers related to your machine. Windows product is what you can change while purchasing the product. You can select from Windows 7 or Windows 8.1 Pro, your choice.

Something else to keep in mind are the data rates available in the Bluetooth standards. The rates are pretty low, so you could stream video but you'd have to do a bunch of compression and probably accept the fact that the video won't be all that good. Bluetooth works for audio because the data rates of compressed audio are very low.
I hope this is the correct forum for such questions..
Is an adapter (the wrapper, that is) really needed in order to put a nano SIM into a micro SIM slot? I tried without one and there doesn't seem any problems. So, my question is, if I continue like this, apart from trivial "non-detection of the SIM card case", what is the worst that could happen? Agreed, those adapters are so cheap to buy, but just wondering...
Just a small hint: You might want to watch out for idle cooler noise if you plan to use it in your office. I once bought one where the description said nothing about it and even in idle it was many times louder than my PC

First of all always look for well known suppliers, that will give you better guarantee.
Then look for a true sinusoidal UPS, which means that the output is sinus shaped resembling the line waveform. The cheaper square-wave devices can create problems to switching power supplies of PC and other electronic devices. For more or less the same reason check the minimum allowed load power factor, this parameters directly deals with current phasing of inductive loads, but for electronic devices lower power factors means that the UPS can tolerate higher waveform distortion and the harmonics generated, again, by switching power supplies of electronic devices.
If you are looking for medium-high power UPS's looking at characteristics you'll find also an harmonic THD distortion, the lower the best.
About surge protection don't worry too much, an UPS device by default give surge protection: A surge is a fast transient overvoltage of power line (up to 200-250% of nominal value), because an UPS output is controlled and regulated you should be theoretically free from them.
Another important characteristic is the autonomy: how many minutes of power it can deliver at nominal power. This defines the dimensions of the battery pack. Choose the right time you need, the batteries are very expensive and are also delicate. Remember that batteries have a lifespan (that depends very much on ambient temperature, higher the temperature shorter the life), good quality batteries will guarantee a life of 18-24 months at 25°C +/-2°C.
I have always used VMWare on my laptop for studying purposes. The laptop runs an i5, 6GB RAM and standard HDD. It has performed pretty well overall for running 1-2 servers and a client over the last few years, but as you can imagine, it's at its limits!
I have picked out a new machine running an i7-4790, 32GB RAM, 256GB SSD with a 2TB HDD. It will be running Windows 8.1 Pro and as far as I can tell, the OS and spec support all the requirements to run Hyper-V.
I am aware there are only 8 threads on the i7, but this machine is only for study purposes so the machines won't be running anything too heavy and only running perhaps 3-4 VM's at once. How will the machine stack up? I know it will be a massive improvement in comparison to what I have now, but I don't want to spend out and then find there is a bottleneck holding me back!
