You might be familiar with the Encryption File System or EFS algorithm if you rather keep your files and folders encrypted. Encryption File System is a built-in feature in Windows 10 which allows users to secure their important files. Although there is an alternative way for you to secure your data on your Windows 10 computer, you can’t ignore the fact that the main advantage of an Encryption File System over BitLocker is that the former can help you encrypt a particular folder rather than encrypting the whole hard drive partition. If you move a file inside a folder encrypted with the Encrypting File System it will automatically get encrypted. There are some users who like this feature but unsurprisingly, there are some that don’t. So if whether you want your files encrypted when you place them in an encrypted folder or if you want to keep it as it is, read on as to how you can do it either way. You can enable or disable automatic encryption of files moved to encrypted folders in Windows 10 using the Registry Editor or the Group Policy Editor. Before you proceed, make sure to create a System Restore Point first because the modifications you’re about to make in your computer might affect its overall functioning so if anything goes wrong, you can always undo the changes. Once you have that covered, refer to the options given below to enable or disable automatic encryption in Windows 10.

Option 1 – Enable or disable automatic encryption using Registry Editor

• Press the Win key + R key at the same time to open the Run dialog box.
• Then type “Regedit” in the field and press Enter to open the Registry Editor and if a User Account Control or UAC prompt appears, just click Yes to proceed.
• After opening the Registry Editor, navigate to this key location: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorer
• Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name the newly create DWORD to “NoEncryptOnMove” and press Enter to save it.
• After that, double click on the NoEncryptOnMove DWORD and set its value to the following preferences:
  • 1 – Disable Auto Encryption of files moved to encrypted folders.
  • 0 – Enable Auto Encryption of files moved to encrypted folders.

• Now close the Registry Editor and restart your computer to successfully apply the changes made.

Option 2 – Enable or disable automatic encryption using the Group Policy Editor

• Press the Win + R keys to open the Run box and type “gpedit.msc” in the field and press Enter to open the Group Policy Editor.
• After that, navigate to this path: Computer ConfigurationAdministrative TemplatesSystem
• Next, look for the “Do not automatically encrypt files moved to encrypted folders” option and double click on it to set the policy. From there, you will see the following description:

“This policy setting prevents File Explorer from encrypting files that are moved to an encrypted folder. If you enable this policy setting, File Explorer will not automatically encrypt files that are moved to an encrypted folder. If you disable or do not configure this policy setting, File Explorer automatically encrypts files that are moved to an encrypted folder. This setting applies only to files moved within a volume. When files are moved to other volumes, or if you create a new file in an encrypted folder, File Explorer encrypts those files automatically.”

• Now select one of the radio buttons below depending on your preference:
  • Not Configured or Disabled: Enable Auto Encrypt of files moved to EFS Encrypted folders.
  • Enabled: Disable Auto Encrypt of files moved to EFS Encrypted folders.
• Then click on the Apply and OK buttons to save the changes made.
• Exit the Group Policy Editor and restart your computer.

Recently Logitech has released a new line of ergonomic mouse products on market, strangely shaped and lifted on a vertical axis Logitech claims that these devices will fix your issues and ease your hand pains for prolonged use of the computer.

The first time I saw this mouse I was not really impressed with its looks and somehow I thought it will not feel good. This all changed when I actually started using it, surprisingly altho strange in looks it does feel much more natural and much less stressful on hand. Also, it felt like I have used it before, personally, I did not need any adjustment period in order to use it fully.

All of that being said I will admit that using it for gaming is still not an option for me, someone might find it ok, especially if they play some games that do not need to be responsive like strategies or similar but for RTS and FPS I will still stick to the typically shaped mouse. This might be just a habit for me but somehow I feel more responsive with the typical mouse, but for anything else, this is the mouse that will keep your hands stress-free.

Now in order to get the mouse to be really recommended it needs to have some good technical specifications as well, looks are not all. The less important detail is that the mouse comes in 3 different colors: Black, white and pink, and its technical specifications are:

Specs & Details

Dimensions

Height: 71 mmWidth: 70 mmDepth: 108 mmWeight: 125 g

Technical Specifications

Sensor technology

• Sensor type: Logitech Advanced Optical Tracking
• Dpi range: 400-4000 dpi (Fully adjustable with 100DPI increments)
• Nominal value: 1000 dpi

Buttons

• Number of buttons: 6 (Left/Right-click, Back/Forward, Middle button, Scroll-wheel with a middle click)

Battery

• Battery type: 1x AA battery (included)
• Battery life: up to 24- months Battery life may vary based on user and computing conditions.

Connection type support

• Logi Bolt USB receiver (included)

Personally, I would recommend this mouse for anyone who does work in front of the computer during the whole workday since it really does loosen grip and strain on hands.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

Once you click next, you can specify the volume size for the pen drive. Select the maximum volume, which is shown as a default unit in MB. As soon as you see the next step, select assign drive letter which will help you view your pen drive once again. Format the partition in the next step. This may be just an extra step because you have already wiped the data clean. But it is always better to be sure. Click Finish to complete the new simple volume wizard which will now be allocated to the USB drive. After you reallocate the unallocated USB drive space, you will be able to view the USB drive storage once again.
