Switchable Graphics Cards on Windows 10

Some laptops come equipped with dual graphics cards, namely a high-performance standalone one (also known as a discrete graphics card) to run graphic intensive programs, and an integrated graphics chip built into to the motherboard. 

Integrated graphics cards are usually sufficient when it comes to running your OS (desktop), and performing basic tasks such as web browsing, video playback and document editing. However, in order to run games or graphic-intensive programs such as video editing, 3D animation, and CAD software, it is recommended that you switch to the discrete graphics card. This process is usually done by your operating system, but Windows 10 also allows you to launch program with the graphics card of your choice. 

The actual procedure of changing your graphics card is very easy. Simply right-click on the program shortcut > Run with graphics processor. You may then click on your desired option to designate the correct graphics card:

Batch Script to Delete Old Files

Batch files can be created for customized tasks such as cleaning up older system, or copying files from one folder to another as a backup. 

Batch Script Command to Delete Files

If you would like to create a batch script that can be used to copy files older than 30 days from one folder to another, while simultaneously deleting the old files from the source folder, here's a sample batch script that can automate the task:

How to Change Your Local IP Address

Your Public IP address is what identifies your computer when you to connect to the internet. It is assigned by your ISP and depending on the type of service you have subscribed to, your public IP may remain the same (Static IP) or is periodically updated (Dynamic IP). Basically if you want to change your public IP then the only way is to get in touch with your ISP or use a proxy service such as Tuxler or Hotspot Shield to hide/spoof your IP address.

Click on Start > Run > type cmd and press Enter to open the Command Prompt. Next, type ipconfig
 to view the current address. Type  ipconfig / release , followed by ipconfig / renew
. 

Change your local IP

Open the Control Panel > Network and Sharing Center > Change Adapter Settings > Network Connections. A list of known connection will be displayed (Ethernet or Wi-Fi). Right-click on the desired connection and select Properties from the contextual menu. Under This connection uses the following items select Internet Protocol Version 4 (TCP / IPv4) and then click onProperties: 

Select the Use the following IP address option instead of Obtain an IP automatically (default) and register the IP address (within the pool of acceptable IP addresses and which is not already in use by another computer), Subnet Mask, Default Gateway and DNS Server addresses:
