Windows 7 tips and tricks,15 best secrets

        Whether you’ve just bought a new PC running Windows 7 or you’ve been using it for a while, there are bound to be things you didn’t know you could do. Whether it’s tweaks to get the desktop the way you want it, tips for troubleshooting or ways to squeeze more performance from Windows 7, I have got it covered with 15 popular Windows 7 tips.

1. Troubleshoot problems
If some part of Windows 7 is behaving strangely, and you don’t know why, then click Control Panel > Find and fix problems (or ‘Troubleshooting’) to access the new troubleshooting packs. These are simple wizards that will resolve common problems, check your settings, clean up your system and more.

2. Startup repair
If you’ve downloaded Windows 7 (and even if you haven’t) it’s a good idea to create a system repair disc straight away in case you run into problems booting the OS later on. Click Start > Maintenance > Create a System Repair Disc, and let Windows 7 build a bootable emergency disc. If the worst does happen then it could be the only way to get your PC running again.

3. Burn images
Windows 7 finally introduces a feature that other operating systems have had for years – the ability to burn ISO images to CDs or DVDs. And it couldn’t be much easier to use. Just double-click the ISO image, choose the drive with the blank disc, click Burn and watch as your disc is created.

4. Calculate more

Calculate more

At first glance the Windows 7 calculator looks just like Vista’s version, but explore the Mode menu and you’ll see powerful new Statistics and Programmer views. And if you’re clueless about bitwise manipulation, then try the Options menu instead. This offers many different unit conversions (length, weight, volume and more), date calculations (how many days between two dates?), and spreadsheet-type templates to help you calculate vehicle mileage, mortgage rates and more.Don’t take any Windows 7 applet at face value, then – there are some very powerful new features hidden in the background. Be sure to explore every option in all Windows applets to ensure you don’t miss anything important.

5. Switch to a projector

Switch to a projector

Windows 7 now provides a standard way to switch your display from one monitor to another, or a projector – just press Win+P or run DisplaySwitch.exe and choose your preferred display. (This will have no effect if you’ve only one display connected.)

6. Get a power efficiency report

Get a power efficiency report

If you have a laptop, you can use the efficiency calculator to get Windows 7 to generate loads of useful information about its power consumption. Used in the right way, this can help you make huge gains in terms of battery life and performance. To do this you must open a command prompt as an administrator by typing ‘cmd’ in Start Search, and when the cmd icon appears, right-click it and choose Run as administrator.
Then at the command line, just type in ‘powercfg -energy’ (without quotes) and hit Return, and Windows 7 will scan your system looking for ways to improve power efficiency. It will then publish the results in an HTML file, usually in the System32 folder. Just follow the path it gives you to find your report. If you fail to open report in browser, same can be opened with notepad as well.

7. Understanding System Restore

Understanding System Restore

Using System Restore in previous versions of Windows has been something of a gamble. There’s no way of telling which applications or drivers it might affect – you just have to try it and see.Windows 7 is different. Right-click Computer, select Properties > System Protection > System Restore > Next, and choose the restore point you’d like to use. Click the new button to ‘Scan for affected programs’ and Windows will tell you which (if any) programs and drivers will be deleted or recovered by selecting this restore point. (Read our full Windows 7 System Restore tutorial.)
8. Set the time zone

Set the time zone

System administrators will appreciate the new command line tzutil.exe utility, which lets you set a PC’s time zone from scripts. If you wanted to set a PC to Greenwich Mean Time, for instance, you’d use the command tzutil /s “gmt standard time”
The command “tzutil /g” displays the current time zone, “tzutil /l” lists all possible time zones, and “tzutil /?” displays details on how the command works. tzutil /s “india standard time” for IST.

9. Calibrate your screen
The colours you see on your screen will vary depending on your monitor, graphics cards settings, lighting and more, yet most people use the same default Windows colour profile. And that means a digital photo you think looks perfect might appear very poor to everybody else. Fortunately Windows 7 now provides a Display Colour Calibration Wizard that helps you properly set up your brightness, contrast and colour settings, and a ClearType tuner to ensure text is crisp and sharp. Click Start, type DCCW and press Enter to give it a try.

10. Clean up Live Essentials
Installing Windows Live Essentials will get you the new versions of Mail, Movie Maker, Photo Gallery and others – great. Unfortunately it also includes other components that may be unnecessary, but if you like to keep a clean system then these can be quickly removed.
If you left the default “Set your search provider” option selected during installation, for instance, Windows Live will install Choice Guard, a tool to set your browser home page and search engine, and prevent other programs from changing them. If this causes problems later, or you just decide you don’t need it, then Choice Guard may be removed by clicking Start, typing msiexec /x {F0E12BBA- AD66-4022-A453-A1C8A0C4D570} and pressing [Enter].
Windows Live Essentials also adds an ActiveX Control to help upload your files to Windows Live SkyDrive, as well as the Windows Live Sign-in Assistant, which makes it easier to manage and switch between multiple Windows Live accounts. If you’re sure you’ll never need either then remove them with the Control Panel “Uninstall a Program” applet.

11. Add network support
By default Windows Live MovieMaker won’t let you import files over a network, but a quick Registry tweak will change this. Run REGEDIT, browse to HKEY_CURRENT_USER\Software\Microsoft
\Windows Live\Movie Maker, add a DWORD value called AllowNetworkFiles and set it to 1 to add network support.

12. Enable virtual Wi-Fi
Windows 7 includes a little-known new feature called Virtual Wi-Fi, which effectively turns your PC or laptop into a software-based router. Any other Wi-Fi-enabled devices within range – a desktop, laptop, an iPod perhaps – will “see” you as a new network and, once logged on, immediately be able to share your internet connection.
This will only work if your wireless adapter driver supports it, though, and not all do. Check with your adapter manufacturer and make sure you’ve installed the very latest drivers to give you the best chance.
Once you have driver support then the easiest approach is to get a network tool that can set up virtual Wi-Fi for you. Virtual Router (below) is free, easy to use and should have you sharing your internet connection very quickly.
If you don’t mind working with the command line, though, maybe setting up some batch files or scripts, then it’s not that difficult to set this up manually. See Turn your Windows 7 laptop into a wireless hotspot for more.

13. Recover locked-up apps
If an application locks up under a previous version of Windows then there was nothing you could do about it. A new Windows 7 option, however, can not only explain the problem, but may get your program working again without any loss of data.
When the lockup occurs, click Start, type RESMON and click the RESMON.EXE link to launch the Resource Monitor. Find your frozen process in the CPU pane (it should be highlighted in red), right-click it and select Analyze Wait Chain.If you see at least two processes in the list, then the lowest, at the end of the tree, is the one holding up your program. If it’s not a vital Windows component, or anything else critical, then save any
work in other open applications, check the box next to this process, click End Process, and your locked-up program will often spring back to life.

14. Fault-Tolerant Help
Windows 7 includes a new feature called the Fault Tolerant Help (FTH), a clever technology that looks out for unstable processes, detects those that may be crashing due to memory issues, and applies several real-time fixes to try and help. If these work, that’s fine – if not, the fixes will be undone and they won’t be applied to that process again.
While this is very good in theory, it can leave you confused as some applications crash, then start working (sometimes) for no apparent reason. So if you’d like to check if the FTH is running on your PC, launch REGEDIT, and go to HKEY_LOCAL_MACHINE\Software\Microsoft\FTH – any program currently being protected by the FTH will be listed in the State key.Experienced users may also try tweaking the FTH settings to catch more problems, and perhaps improve system stability.

15. Automatically switch your default printer
Windows 7′s location-aware printing allows the operating system to automatically switch your default printer as you move from one network to another. To set this up, first click Start, type Devices, and click the Devices and Printers link.Select a printer and click Manage Default Printers (this is only visible on a mobile device, like a laptop – you won’t see it on a PC).
Choose the “Change my default printer when I change networks” option, select a network, the default printer you’d like to use, and click Add. Repeat the process for other networks available, and pick a default printer for each one. And now, as you connect to a new network, Windows 7 will check this list and set the default printer to the one that you’ve defined.

DDR SDRAM

DDR SDRAM (double data rate synchronous dynamic random access memory) is a class of memory integrated circuits used in computers. It achieves nearly twice the bandwidth of the preceding [single data rate] SDRAM by double pumping (transferring data on the rising and falling edges of the clock signal) without increasing the clock frequency

With data being transferred 64 bits at a time, DDR SDRAM gives a transfer rate of (memory bus clock rate) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s.

DR SDRAM for desktop computers DIMMs have 184 pins (as opposed to 168 pins on SDRAM, or 240 pins on DDR2 SDRAM), and can be differentiated from SDRAM DIMMs by the number of notches (DDR SDRAM has one, SDRAM has two).

DDR for notebook computers SO-DIMMs have 200 pins which is the same number of pins as DDR2 SO-DIMMs. These two specifications are notched very similarly and care must be taken during insertion when you are unsure of a correct match.

DDR SDRAM operates at a voltage of 2.5 V, compared to 3.3 V for SDRAM. This can significantly reduce power consumption. Chips and modules with DDR-400/PC-3200 standard have a nominal voltage of 2.6 Volt.
Like the ordinary SDRAM, DDR can be also classified into two types: 200MHz (100MHz DDR) PC1600 SDRAM and 266MHz (133MHz DDR) PC2100 SDRAM. The table below shows all the memory types available in the today's memory market:

Memory	Frequency, MHz	Memory Bus, bit	Memory Bus Bandwidth, MB/sec	Supported Platforms
PC100 SDRAM	100	64	800	Pentium III (i440BX, VIA Apollo Pro 133A, i815) Athlon (AMD 750, VIA KT133)
PC133 SDRAM	133	64	1064	Pentium III (VIA Apollo Pro 133A, i815) Athlon (VIA KT133)
PC800 RDRAM	800	16	1600	Pentium III (i820)
Dual Channel PC800 RDRAM	800	32	3200	Pentium 4 (i850)
PC1600 DDR SDRAM	200	64	1600	Pentium III (VIA Apollo Pro266, ALi Aladdin Pro 5) Athlon (AMD 760, VIA KT266, ALi MAGiK 1)
PC2100 DDR SDRAM	266	64	2128	Pentium III (VIA Apollo Pro266, ALi Aladdin Pro 5) Athlon (AMD 760, VIA KT266, ALi MAGiK 1)

The memory modules exterior was also a bit modified. Although the DDR modules size remained the same, they have more pins - 184, while the regular PC100/PC133 SDRAM DIMM modules have only 168 pins.
Besides a larger number of pins, new DDR SDRAM DIMM modules feature lower voltage, 2.5V, which helps to reduce EMI (compare with 3.3V by the regular SDRAM). As for the latency, it is almost the same as by PC100/PC133 SDRAM modules and much lower than by RDRAM.

In addition to speed, DDR2 and DDR3 were developed to run at lower voltages than regular DDR RAM, resulting in less power needed to run memory. DDR used 2.5v. DDR2 runs off 1.8v and DDR3 1.5v.

How much memory do you need?

When it comes to adding system memory, the general rule of thumb is the more, the better.
On average, doubling the amount of memory in your system will give you ample "space" to work and make an obvious difference in overall speed, especially with today's memory-hungry applications, such as office programs and graphics-intensive games. You'll be able to run more programs at once, and your system will be less likely to lock up or behave strangely. You'll also find it easier and faster than ever to edit graphics and sound. The bottom line is that adding memory makes your computer more efficient and allows you to do more things at once.

The Crucial Memory Calculator
How does more RAM affect system performance? Explore our database of benchmark test results to see the impact of memory on various motherboard, processor, and operating system combinations.
If you build systems, the Memory Calculator can show you how much RAM to install for optimum performance.

What is the maximum amount of RAM the Windows operating system can handle?

That depends on two factors: the amount of memory your computer hardware can handle, and the amount of memory your Microsoft® Windows® operating system (OS) can handle.

First, your computer hardware (motherboard) is designed to hold a maximum amount of RAM. When you look up your computer in the Crucial Memory Advisor™ tool or scan your system with the Crucial System Scanner, you will see the system maximum listed on the page that shows the compatible upgrades for your system.

Second, the OS maximum is the maximum amount of memory that your particular version of Windows, Linux, or Mac® OS can handle.

When purchasing your memory upgrade, make sure that you do not exceed the lower of the two maximums (OS and computer maximums.) Too much RAM can lower your system's performance or cause other problems. (In most cases, the system maximum is lower than the OS maximum.)

Installing a RAM DDR / SODIMM. Diff b/w RAM's Types and Speed and Amount of Mmry needed?

What is the difference between DDR2, DDR, and SDRAM?

Most desktops and notebooks use one of the three most popular types of synchronous dynamic random access memory (SDRAM) for the main system memory. Single data rate (SDR) SDRAM is the older type of memory, commonly used in computers prior to 2002. Double data rate (DDR) SDRAM hit the mainstream computer market around 2002, and DDR2-based systems hit the market in mid-2004.

DDR SDRAM is a straightforward evolution from SDR SDRAM. The big difference between DDR SDRAM and SDR SDRAM is that DDR reads data on both the rising and falling edges of the clock signal, so the DDR module can transfer data twice as fast as SDR SDRAM.

While DDR has a limited clock rate, the evolutionary changes to DDR architecture enable DDR2 to achieve speeds beyond that of DDR, delivering bandwidth of 5.3 GB per second and beyond! Because DDR2 is able to operate with faster bus speeds, your memory doesn't hold back the performance of your processor.

Generally speaking, motherboards are built to support only one type of memory. You cannot mix and match SDRAM, DDR, or DDR2 memory on the same motherboard in any system. They will not function and will not even fit in the same sockets.

The right type of memory to use is the one that your computer takes! The easiest way to find the right memory for your computer is to look up your system in Crucial's Memory Advisor tool. The Memory Advisor tool will list only compatible memory for your system.

What is the difference between PC2100 (DDR266), PC2700 (DDR333), and PC3200 (DDR400)?

Although these are all types of double data rate (DDR) memory, the varying numbers refer to the different speeds of memory your computer was designed for. Crucial no longer carries PC2100 (DDR266) memory, but PC2700 (DDR333) memory and PC3200 (DDR400) are backward-compatible with PC2100.

Memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. However, your system will operate at the speed of the slowest module or system component (the "lowest common denominator" effect).

One thing to keep in mind is that the memory does need to be the same type-for example, SDRAM cannot be mixed with DDR, and DDR cannot be mixed with DDR2. We recommend that you use the Crucial Memory Advisor™ or System Scanner tools to find the right memory for your computer.

How to solve low memory problems?

Normally this warning message shows when you run many programs same time than the RAM installed on your computer is designed to support.  Your can solve this problem by increasing the system paging file size also called as virtual memory. Using this virtual memory windows moving information to and from the paging file for fast processing.  This will free up enough RAM for other programs to run properly.

To increase the system page file follow the give path:

Control Panel > System > Advanced > Click on Settings (Under Performance) > Advanced > Change

Here under Drive (Volume label), you have option to select any of your hard disk drive, but the best choice is, select any drive other than C drive for virtual memory.

 

Set the double Initial & Maximum Size of your Virtual Memory. Here set initial size 700 MB and maximum size up to 1000MB; you can change this size according to the free space available on your hard drive.
