5 uncommon  Windows 7 tips, tricks and secrets Pc and Laptop

 today i will tell u one of my favorite things about windows 7 and help u understand the new system restore and the FTH function . follow this blog and u will get some random info about  technology every day. :) if u have any requests leave them in the comments and have a nice day and try this stuff out also if u have any info that i can use pls feel free to share it with me :)

1. 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.

2. Activate XP mode (for us old school dudes XD )

If you've old but important software that no longer runs under Windows 7, then you could try using XP Mode, a virtual copy of XP that runs in a window on your Windows 7 desktop. But there's a big potential problem, as XP Mode only works with systems that have hardware virtualisation (AMD-V or Intel VT) built-in and turned on. If you've a compatible CPU then this may just be a matter of enabling the option in your BIOS set-up program, however some high profile brands, including Sony Vaio, disable the setting for "security reasons". And that blocks XP Mode from working, too.

One solution has emerged, but it's a little risky, as essentially you'll have to alter a byte in your laptop firmware and hope this doesn't have any unexpected side-effects. Gulp.

A safer approach might be to use VirtualBox, a virtualisation tool that doesn't insist on hardware support, but then you will need to find a licensed copy of XP (or whatever other Windows version your software requires) for its virtual machine.

3. Enable virtual Wi-Fi ( u can also do this with phones witch may be in the next blog :) )

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. 

4. Get a power efficiency report ( easier then downloading an app for that )

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.

5. 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. A post on Microsoft's Ask The Performance Team blog (bit.ly/d1JStu) explains what the various FTH Registry keys mean.
