Remove formatting in Word from any pasted text.


When copying text from another document or Internet web page and pasting it into Microsoft Word, Word will keep the formatting of the text. For example, if you were to copy the text on this page to a Word file, this text would remain bold, and this text would remain blue. To remove the formatting in Microsoft Word from any text highlight the text and press the shortcut key Ctrl + Space-bar  This will set the text to the default font, remove the formatting, and even remove links.

Alternatively you can use the Paste Special option or Keep Text Only option in Microsoft Word to paste the text with no formatting.

Bonus Tip: In most versions of Windows Ctrl + Windows Key + V will also often paste text as plain text.

Windows 8: How to Create a New Hard Drive Partition

Windows-8-Disk-Partition
Disk partitioning is essentially separating the hard disk into different sections or parts for storage. If you want to try a new operating system without overwriting your main Windows drive, you can do this partitioning the hard drive.
Partitioning the hard disk also makes it possible to multiboot different operating systems. In addition to creating multiboot configurations, you can also use partitions as extra storage mediums for specific files or for backing up important files.

Benefits of Having Another Partition:

  • Backup System Files
  • Install multiple Operating Systems
  • Extend the functionality of the hard drive
  • Improve security (you can use the other partition in case one fails)

Creating a Partition on Windows 8

Hold the Windows logo key on your keyboard and press “R” (Winkey+R). This will launch the Run the utility. Type “diskmgmt.msc” inside the text box and press Enter. This will open the Windows Disk Management utility. This is where you can format, create, and delete hard drive partitions.
Run diskmgmt
In order to create a partition, you need unallocated space. Unallocated space is basically disk space that is not formatted or not prepared for storage. Formatting is the act of preparing a disk space for storage. It similar to building a foundation for a place to be inhabited. Thus, unallocated space is just useless blank space with no “foundation” or format.
To create unallocated space, you need to shrink your hard drive. When you shrink your hard disk, the remaining space becomes unallocated.
To do this, right-click your main drive and select “Shrink Volume.”
Shrink Volume
Now you need to enter the amount you want to shrink the hard disk by in megabytes (1000 megabytes = 1 gigabyte). For example if you want to create a 1 gigabyte partition, enter 1,000 megabytes in the text box. Now click “Shrink.”
The Disk Management Utility will show you the maximum amount of shrink space available. That’s the maximum size that can be allocated to the new partition.

You will then see the region of unallocated space (shaded black). Remember, this space is not yet usable.

Now you need to create “foundation” or format for the unallocated space. This will allow for the space to become usable.
Right-click the region of unallocated space and select “New Simple Volume.”

This will launch the New Simple Volume Wizard. This will guide you through the installation process.

Assign the disk a drive letter. You can choose any drive letter that is not currently in use.

Select a file system for the disk. The file system is basically the type of format or “foundation” the storage device has. If you plan on installing a Windows OS to the partition select the “NTFS” file system.

Name the partition in the “Volume Label” text box.  You can choose any name for your partition. As you can see, we’ve name ours “Vikitech.”

Now click “Finish” to create the new partition.

As you can see, this is the new partition that was just created.

Final Thoughts:

Having another partition is a great asset in case your main one fails. You can use the extra partition to backup important files and install another OS. This is also a great alternative if your PC does not support virtualization. Now you need to always be careful not to format your main disk partition. This will erase all of your files.
