Extract Multiple Zip, Rar and other Archives Simultaneously

If you have Winrar installed, just select all the archives, right-click and select 'Extract each archive to separate folder'.

This can also be done with ExtractNow. Install it and just drag the archives into the ExtractNow window anc click the Extract button.

I haven't tested this with 7Zip or Winzip yet. Will let you know after using them.

Edit Text in Scanned Documents

Scanned documents are usually images, which means they cannot be modified directly. To edit the text in a scanned document, it has to be made editable. This is where OCR tools are of use.
OnlineOCR does just that. It's a site which converts scanned images of documents and gives you the editable text.

OnlineOCR accepts pdf, tiff, jpg, png, bmp, pcs, zip files as input. Output formats supported are plain text, rtf, pdf, word, excel and html. It supports 28 languages. The website also claims to preserve the formatting in the original file. However, I haven't tested that yet. Till then, enjoy!

More ways to edit text in scanned images are mentioned in below articles:

Disable Automatic Windows Update in Vista

Windows updates are important, but quite frustrating when it happens at the wrong time. Here's my problem with it - My internet plan has a bandwidth cap of 1 GB per month, but no caps are applicable during the night; its unlimited at night. So I would prefer that Windows updates are downloaded and installed when my internet connection is free of bandwidth caps. Similarly, you may also not want those updates to be installed just before your all important presentation. A manual update of Windows give you more control of when to download and apply it. So, here's how to do it.

Steps to Disable Automatic Updates in Vista

1. Open Windows Update by clicking the Windows Start button and type Windows Update. The Windows Update program is listed. Click it. Alternatively, you can open the tool from Control Panel.

2. On the left pane, click Change Settings.

3. Select the 'Never check for updates' option and click Ok.

That should do it. Remember to manually update Windows from now on. To enable automatic updates again, just follow the same steps and select 'Install updates automatically' option.

Best way to Disable USB Autorun in Windows

Autorun is one "feature" or bug in Windows that must be disabled quickly. Whenever you plug in a USB drive, CD or DVD, Windows automatically executes the instructions in the Autorun.inf file that may be present in any of those removable devices. This is how most computers get infected with viruses, trojan, malware etc when a USB drive is plugged in. So it is highly recommended to turn off Autorun in Windows. After looking around quite a bit, here is the best way I found to disable it in Windows.

Disable Autorun in Windows Vista and XP
The below tip involves editing the Windows Registry. Please take a backup of the registry before proceeding.

1. Open the Windows Registry Editor. Go to Start - Run. Type Regedit and press Enter. In Vista, you can just type it in the box above the Windows button.

2. In the registry editor, navigate to

3. Right-click IniFileMapping key select New - Key. Name the new key as Autorun.inf

 4. Right-click the value of the newly created key and hit Modify.

5. Enter @SYS:DoesNotExist in the Value data box. Click Ok.

6. Now Navigate to

7. Delete the MountPoints2 key.

That's all. This will prevent the auto execution of malicious programs when a USB stick or DVD is inserted.
Note: Your computer can still be infected if you manually click the virus program. But this tip will atleast give you a first level of protection. Cheers!
