How To Create a Shortcut That Lets a Standard User Run An Application as Administrator

Posted by Unknown Senin, 28 Oktober 2013 0 komentar




Want to allow a standard user account to run an application as administrator without a UAC or password prompt? You can easily create a shortcut that uses the runas command with the /savecred switch, which saves the password.

Note that using /savecred could be considered a security hole – a standard user will be able to use the runas /savecred command to run any command as administrator without entering a password. However, it’s still useful for situations where this doesn’t matter much – perhaps you want to allow a child’s standard user account to run a game as Administrator without asking you.

Enabling the Administrator Account

First you’ll need to enable the built-in Administrator account, which is disabled by default.

To do so, search for Command Prompt in the Start menu, right-click the Command Prompt shortcut, and select Run as administrator.



Run the following command in the elevated Command Prompt window that appears:


net user administrator /active:yes



The Administrator user account is now enabled, although it has no password.

To set a password, open the Control Panel, select User Accounts and Family Safety, and select User Accounts. Click the Manage another account link in the User Accounts window.



Select the Administrator account, click Create a password, and create a password for the Administrator account.


Creating the Shortcut

Now we’ll create a new shortcut that launches the application with Administrator privileges.

Right-click the desktop (or elsewhere), point to New, and select Shortcut.



Enter a command based on the following one into the box that appears:


runas /user:ComputerName\Administrator /savecred “C:\Path\To\Program.exe“

Replace ComputerName with the name of your computer and C:\Path\To\Program.exe with the full path of the program you want to run. For example, if your computer’s name was Laptop and you wanted to run CCleaner, you’d enter the following path:


runas /user:Laptop\Administrator /savecred “C:\Program Files\CCleaner\CCleaner.exe”



Enter a name for the shortcut.



To select an icon for your new shortcut, right-click it and select Properties.



Click the Change Icon button in the Properties window.



Select an icon for your shortcut. For example, you can browser to CCleaner.exe and choose an icon associated with it. If you’re using an other program, browse to its .exe file and select your preferred icon.



The first time you double-click your shortcut, you’ll be prompted to enter the Administrator account’s password, which you created earlier.



This password will be saved – the next time you double-click the shortcut, the application will launch as Administrator without asking you for a password.

As we mentioned above, the standard user account now has the ability to run any application as Administrator without entering a password (using the runas /savecred command to launch any .exe file), so bear that in mind.

The Administrator password is saved in the Windows Credential Manager – if you want to remove the saved password, you can do it from there.

How to Increase Reliance Netconnect internet speed

Posted by Unknown Senin, 14 Oktober 2013 0 komentar

Reliance Netconnect+ would give the fastest internet speed till your unlimited plan gets over. But after you consumed 100% of allotted quota, you will get only 144kbps speed which is very poor and takes more than 1 minute to load a single webpage. Don’t worry, in my experience i found some tricks to increase reliance netconnect internet speed.

Basic Tricks

1Delete temporary internet files. Go to START — > Run– > type %temp% and then press enter. Delete all the files and folders in the opened window.
2Delete prefetch files from your system. Go to START -> Run-> type prefetch and press enter. Delete all the files and folders in  Prefetch window.
3Delete cookies and browsing history.
4While roaming always select mode as “Hybrid” in dialer settings. (Dialer->settings->mode)
5Check whether you have 4-5 signal bars at the top right corner. If you don’t have 4-5 signal bars, contact Reliance customer service to check coverage.

How to bring back Chrome's old New Tab page

Posted by Unknown Sabtu, 12 Oktober 2013 0 komentar
The largest element on Chrome's redesigned New Tab page -- the Google search bar -- is redundant. If you have gotten into the habit of entering search terms in Chrome's address bar, which Google refers to as the omnibox, then the Google search bar and large Google logo are just taking up space on the New Tab page.

Thankfully, you can return to the old New Tab page, and do so without installing an extension. Here's how:

  1. Type or copy and paste chrome://flags into Chrome's omnibox
  2. Search for "Enable Instant Extended API"
  3. Change its setting from Default or Enabled to Disabled
  4. Restart Chrome


Now when you open a new tab, you'll be greeted with the old New Tab page, which displays tiles of your most visited pages or your Chrome apps.

According to this option's description, in addition to bestowing upon you the renovated New Tab page, it also is good for "extracting search query terms in the omnibox, a spruced-up omnibox dropdown and Instant previews of search results as you type in the omnibox." I didn't notice my omnibox behaving any differently after I disabled this API, but if you do or are wary of making such a tweak, I have two extensions for you to try instead.


The second is the New Tab Redirect extension. It lets you set a custom URL for your New Tab page to open to.The first is an extension I wrote about earlier this year called New MetroTab. It lends a Microsoft Metro live tiles look to the New Tab page.

How To: Get the fastest Internet connection ever

Posted by Unknown Rabu, 09 Oktober 2013 0 komentar
It has always been a geek’s dream to have the fastest Internet connection ever, and we bet you would desire the same too. Almost all those who are hooked on to the Internet to surf, download or entertain themselves would definitely be owning an broadband connection at home. It could be via a telecom service provider, your local cable guy or 4G wireless Internet providers. Some even own 3G USB Internet dongles for their work and entertainment while being outdoors. Most smartphone users today also opt for 3G Internet services on their phones and tablets. All these connections can be individually used on your PCs, laptops and handhelds efficiently. 
Download, setup and activate the utility
Download, set up and activate the utility


Though you can connect them all together on a single PC and access the Internet, the Internet speed will be only drawn from the last connected network, leaving the others unused. For instance, you have four different Internet connection sources A, B, C and D.  Your PC will access Internet from A when it is connected. The moment you initiate a connection from B, the PC will divert all network connections via B, leaving A unused. The same happens when C is initiated; A and B are unused and it applies the same to D. The operating system is not smart enough and does not know that there are multiple Internet networks. It needs help, but is unable to do so. In Linux, it is possible to do so by tweaking the kernel, adding some modules and running some scripts that will tell the operating system about the various active Internet connections and balance the network load accordingly. On Windows, it is not possible and a third-party utility is required.

Clubbing all your available Internet connections into one single mammoth pipeline was not possible until Connectify, a well known software development company which developed Connectify hotspot, a virtual software router for Windows, stepped in. It kickstarted a campaign to help collect funds for the project and achieved it. It finally came up with Connectify Dispatch, a utility to connect to multiple Internet connections for combined speed and reliability. Using this utility, you can now connect all your available Internet connections – be it from a DSL modem, a wired cable connection, a wireless router, a tethered mobile phone or a USB Internet dongle – into a single mega broadband connection. Read ahead to know how you can do it in four simple steps.

Step 1: Download Connectify Dispatch and install it. It is not a free utility and there are no demo versions available. The utility costs Rs 5,114 for a lifetime license, which includes the HotSpot Pro utility as a bundle. Optionally, you can opt for a one year license for Rs 4,023, but we recommend the lifetime offer, which is reasonably cheaper than this one. Once installed, activate the utility and you can see it running, but not active, in the system tray.

Step 3: Double-click on the Connectify icon in the system tray to pull up the Dispatch user interface. Here you see the Dispatch utility, which is not started as yet. There is a graph available to know the bandwidth of all your available connection’s, and the overall bandwidth speed. Also, you will see the number of active adapters (Internet connections) in the lower half. Other icons available are Hotspot (to start the Wi-Fi hotspot) and Settings (to tweak a few changes). 

Step 4: Connect, enable or start all your Internet connections. Once all are active, hit the ‘Start Dispatch’ button on the Dispatch window and you are ready to cruise the Internet highway by utilising all the Internet connections simultaneously. The Dispatch utility will automatically combine all the Internet connections together, analyse each one of them and route the Internet traffic accordingly whenever and wherever necessary. You can check the download speeds by downloading some large file, video or torrent. You will definitely notice a difference.

How we tested
1. Internet connection A – Tikona Wireless 4G broadband via Ethernet – 2 Mbps speed.
2. Internet connection B – Tata Photon Plus 3G USB internet dongle – Speeds up to 3.1 Mbps.
3. Internet connection C – Tata Photon Plus 3G USB internet dongle – Speeds up to 3.1 Mbps.
4. Internet connection D – Tata Photon Plus 3G USB internet dongle – Speeds up to 3.1 Mbps.
Set bandwidth limitations for each Internet connection

The setup was done on a Lenovo laptop and was conducted inside a house in the suburbs of Mumbai. The testing was done at night around 1 AM when we could obtain maximum speeds and minimum interferences from any other networks in the surroundings. As we all know, the USB 3G Internet dongles claim maximum speeds of up to 3.1 Mbps, but this entirely depends from area to area. In our case, the maximum Internet speeds we acquired was between 800 Kbps to 1.5 Mbps at any given time. The Tikona connection was stable at around 2 Mbps. In all, estimating the USB dongles gave us around 1.2 Mbps speeds and the Tikona Wireless giving us around 2 Mbps speeds, clubbing them together, the speeds we acquired was a little more than 6 Mbps.

Testing and using the Connectify Dispatch for a few hours, we definitely state that the utility works and can benefit those who are looking for higher broadband speeds. BitTorrent is designed to make use of many network sockets simultaneously, which makes it a perfect application for Connectivity Dispatch.

Other options possible with Dispatch
You can further tweak the Dispatch utility to benefit your work. You can set up individual applications to use particular Internet connections to balance the load manually too. In this way, for example, you can download multiple files from Hotfile, Rapidshare, Mediafire and other similar file hosting websites that have IP-based time limitations to download the next file. It can also benefit those who want to download particular files faster than others, such as torrents can be on a faster bandwidth while smaller files can use the slower Internet connections. 
Start Hotspot with a combined speed and share it to other devices

You can also use Dispatch to balance the load as per your will. You can set it to keep particular Internet connections as standby or backup connections in case any one of them fails. Other options available are to use DNS servers other than the ISP provides you. You can use Google or OpenDNS to your advantage. You can also meter individual connections to limit the Internet usage so that you don't exceed the download limits according to your plans. This can be done on daily, weekly or monthly rules according to your download plans. Lastly, you can set Dispatch to draw the bandwidth from the available connections that have the best latency and reliability.

Finally, if you have bought the Dispatch + Hotspot utility together (Rs 5,114), you can start up HotSpot and share this combined mega-Internet pipeline to all other computers and devices on the network wirelessly or using a router.

Connectify Dispatch is a very powerful utility that can benefit small and large business environments too. Take for example, a large organisation that provides most of the employees with a USB Internet dongle for use when they are travelling. When they are not travelling, the Internet connection is wasted as they are lying unused and the office Internet connection is used at work. By using these dongles on a PC installed with Dispatch, the entire bandwidth can come in handy for the entire office to have a faster Internet connection. Other areas where Dispatch can come in very handy is for video chat, online high-definition and 3D video entertainment, distributed or cloud gaming, online backups and data sync servers, remote desktop sharing, and a few others.

Why Is Serial Data Transmission Faster Than Parallel Data Transmission?

Posted by Unknown Selasa, 08 Oktober 2013 0 komentar


SATA hard drive connections are faster than older PATA hard drive connections and the same can be said for external cabling standards, but this is counter-intuitive: why wouldn’t the parallel transmission be faster?
Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites.

The Question

SuperUser reader Modest is curious about the data transfer rates of parallel and serial connections:
Intuitively, you would think that parallel data transmission should be faster than serial data transmission; in parallel you are transferring many bits at the same time, whereas in serial you are doing one bit at a time.
So what makes SATA interfaces faster than PATA, PCI-e devices faster than PCI, and serial ports faster than parallel?
While it’s easy to fall into the reasoning that SATA is newer than PATA, there must be a more concrete mechanism at work than just age.

The Answer

SuperUser contributor Mpy offers some insight into the nature of the transmission types:
You cannot formulate it this way.
Serial transmission is slower than parallel transmission given the same signal frequency. With a parallel transmission you can transfer one word per cycle (e.g. 1 byte = 8 bits) but with a serial transmission only a fraction of it (e.g. 1 bit).
The reason modern devices use serial transmission is the following:
  • You cannot increase the signal frequency for a parallel transmission without limit, because, by design, all signals from the transmitter need to arrive at the receiver at the same time. This cannot be guaranteed for high frequencies, as you cannot guarantee that the signal transit time is equal for all signal lines (think of different paths on the mainboard). The higher the frequency, the more tiny differences matter. Hence the receiver has to wait until all signal lines are settled — obviously, waiting lowers the transfer rate.
  • Another good point (from this post) is that one needs to consider crosstalk with parallel signal lines. The higher the frequency, the more pronounced crosstalk gets and with it the higher the probability of a corrupted word and the need to retransmit it. [1]
So, even if you transfer less data per cycle with a serial transmission, you can go to much higher frequencies which results in a higher net transfer rate.
[1] This also explains why UDMA-Cables (Parallel ATA with increased transfer speed) had twice as many wires as pins. Every second wire was grounded to reduce crosstalk.
Scott Chamberlain echoes Myp’s answer and expands upon the economics of design:
The problem is synchronization.
When you send in parallel you must measure all of the lines at the exact same moment, as you go faster the size of the window for that moment gets smaller and smaller, eventually it can get so small that some of the wires may still be stabilizing while others are finished before you ran out of time.
By sending in serial you no longer need to worry about all of the lines stabilizing, just one line. And it is more cost efficient to make one line stabilize 10 times faster than to add 10 lines at the same speed.
Some things like PCI Express do the best of both worlds, they do a parallel set of serial connections (the 16x port on your motherboard has 16 serial connections). By doing that each line does not need to be in perfect sync with the other lines, just as long as the controller at the other end can reorder the “packets” of data as they come in using the correct order.
The How Stuff Works page for PCI-Express does a very good explination in depth on how PCI Express in serial can be faster than PCI or PCI-X in parallel.
TL;DR Version: It is easier to make a single connection go 16 times faster than 8 connections go 2 times faster once you get to very high frequencies.
