How to block your computer so only you can start it.

Almost everyone has its own user and password to access Windows. A measure that although it protects us so no one can access our computer and dispose of the information have in it, it’s not entirely reliable. Because in case our laptop is lost or stolen, anybody could have access to all of our information if they boot the computer through a CD, DVD or USB, or even installing another OS.

Therefore, if we want to improve our data security, besides encrypting, we can set a Hard Drive booting password and avoid that someone can start the system easily. For this, we have to enter the BIOS or UEFI and in its settings add a password to block the computer so no one can start it up without it.

According to the manufacturer, the method to access our computer’s BIOS may vary, though normally you can enter by pressing any of the keys Supr., F2, F10, F12, Esc, etc. while the computer is starting. If we don’t make this way, then check the user manual or contact the manufacturer.

How to block from BIOS or UEFI our computer so no one can start it

Once in the BIOS we must look for the HDD password option that will probably be under the security tab. Due to that the menu options may vary from one manufacturer to another, in case you don’t find the option, it’s advisable to check the user manual of the motherboard. Once we have found this option, we will set a safe password and after that restrict the start mode so it can only be booted from the hard drive so blocking your computer.

How to access UEFI Settings on Windows 10

And the thing is that if we would like to choose which device to initialize during the booting process, configure RAM or graphic card frequency, adjust fan speed, among other things, the only way we have to do all of those is to access the BIOS and change the settings.

Barely 6 years ago and thanks to an important agreement held by the main technology companies, it was decided to replace the BIOS for a new system called UEFI. A new standard that was introduced commercially soon after and that offers various benefits in comparison to the BIOS.

Does the Power Supply Unit ( PSU) influence PC performance?

When choosing the computer’s components, we look at how performance will be affected, comparing the processor, graphics card, or even RAM. However, is it possible that other components such as the power supply can affect the computer’s performance? Let’s analyze it.

We have commented on various occasions that the power supply unit (PSU) is a very important component of the computer, since it is responsible for providing power to the other parts. In the event that it fails, some other component may break, which is why it is important to always choose a high quality power supply.

Power Supply

Power supply: don’t overdo the wattage

A tendency when building a PC by pieces is to choose a power supply with too high a wattage, such as any power supply of more than 600 watts. In my analysis of the Xiaomi Smart Socket I was able to check how much my PC was consuming at rest and in high performance mode, and the results surprised me, because I realized that I had bought a power supply with too high a wattage, and I could have taken advantage of that money to improve other components.

Can Windows 10 Cloud stand up to Chrome OS?

Mobility, work in the cloud, mobile devices, telecommuting; all of them, among many others, are concepts that have become increasingly common elements in our daily lives, whether it’s while moving in our home or professional environment.

As time passes, regular users of technology, whether in desktop environments or those focused on mobile devices, have been looking for ways to work with all their products in a more centralized way. Evidently the Cloud has been taken as base, thanks to different services using Internet, dealing with lighter devices and applications that allow greater mobility and having all of them, at both software and hardware levels, as unified as possible.

Because of this in the middle of last year 2015 Microsoft, as you all know, made available to users the latest version of its popular operating system, Windows 10. From the beginning, the company has tried with this launch to create a “Windows 10 environment” that allows its clients to work with all their data on all types of devices based on the same system and from anywhere, facilitating their access through PCs, platforms and, again, through the Cloud. However, so far, it has not satisfied the expectations that were initially set on this project.

However there is another environment that is growing exponentially, although somewhat slower on the old continent, Chrome OS, an alternative open source operating system from Google that in the future aims to become a direct competitor of Windows. If something characterizes this proposal is precisely its lightness, good performance and being multi platform; that is to say, it covers a large part of the needs of the current users. In addition, now that manufacturers are launching interesting products specially designed for this free platform and it has already begun its compatibility with Android apps, it is expected that its breakthrough in the near future will be much greater.

Will we see a Windows 10 Cloud vs. Chrome OS confrontation?

For some time now the people at Redmond have been trying to make PC manufacturers ignore Chrome OS, something that although they have achieved until now, it’s beginning to change, so it is expected that Microsoft will have to try something new to not be left behind in some environments. This is the thought behind the arrival of Windows 10 Cloud, a new variant of the popular operating system, namely a simplified version of the original Windows focused on the cloud and designed to run all kinds of applications from the company’s official store on all types of devices, in addition to a lower cost for users and even possibly free for PC manufacturers.
