Recover Deleted Files

A recent client accidentally deleted several important files and removed them from the recycle bin. Another client had done a system rollback that effectively removed important files.

Happily, deleting a files does not remove them. Only the references to the files are gone. Usually some files can be recovered if you know what file type you’re looking for and if the file location on the hard drive hasn’t been overwritten by new files. This is why it’s important to not install a program to recover files. Just the act of installing something will overwrite the data you want to recover.

I like Recuva Portable, available for free here:

The Portable version can run from a USB or CD and does not need to be installed or be copied onto the main hard drive.

Test RAM on a Mac

If you have new RAM in your Mac or if you are trying to diagnose weird shutdowns and problems, you should consider testing your RAM. An easy way to do so is to follow these instructions from the command-tab article “How to Test RAM Under Mac OS X“.

  1. Download the memtest_422.zip file and install the program.
  2. Shut down and then restart the computer holding down Command and S keys.
  3. When at the prompt, type “memtest all 2” which will test all the memory twice.

This will take several hours to run but should diagnose the tricky problem of bad RAM.

Access Netflix, Hulu, Pandora from outside US

A colleague working abroad wanted to get streaming Internet content (videos from Netflix and Hulu, music from Pandora). But those services only have content distribution deals for US customers so they block non-US subscribers. How can those services be tricked? By connecting through a US server. Here’s how.

VPN

A Virtual Private Network or VPN is used by many companies to secure traffic and make your computer appear as if it is on the local corporate network. Internet traffic is typically tunneled through the corporate servers making it appear as if the web browsing is originating on those corporate servers.

Finding a VPN Provider

You can set up a VPN yourself with OpenVPN, but it’s fairly complicated.

I suggest using a paid VPN service. Because all your traffic goes through these servers and your bandwidth is limited by the speed of the VPN servers, you need to chose a VPN service that you can trust. Most VPN providers that I found look a little shady. There are lots of fake review sites as well that are clearly promoting particular sites.

StrongVPN

StrongVPN is a provider that describes their corporate history, locations, and services in detail. Their corporate headquarters is in California and by all appearances, they aren’t a shady company. As of this writing, they have 94 servers in the US in 8 locations.

They have setup instruction for Windows, Mac and Linux.

They have a page explaining how to make sure that Hulu, etc. will work for you:
Unblocking Geographically Blocked Sites

My colleague used StrongVPN without any problems. There is typically additional lag by going through the extra hop of a VPN, but the bandwidth from StrongVPN was good and it worked well enough to watch streaming shows while outside the US.

Slingbox

Unrelated to VPNs, another solution for video when traveling abroad (or anywhere) is Slingbox, which allows you to access your home cable box or DVR. See my old post: Watch Your Home Team with Slingbox.

Manage License Keys for Windows and Office

Find Product Keys

Most businesses have trouble keeping track of their license keys. A tool to see what keys you are using for Windows and Microsoft Office is:

LicenseCrawler by Klinzmann

It’s free software. The author jokingly requests that users send him a picture of their hometown instead of payment. Must be funny in German.

Still, it’s simple and streightforward software to help you find the product keys.

Change Microsoft Office Key

If you install Microsoft Office and find that the key is already in use, there is a quicker way to try another key instead of performing a full uninstall and reinstall of Office.

  • Click, Start – Run
  • Type Regedit
  • Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\”version”\Registration
  • Click the plus (+) sign and you should find a couple of items that you need to delete: DigitalProductID and ProductID. One or both of these should contain a 32-character {GUID} (globally unique identifier).
  • Save and close the registry, reboot, and start MS Office again. It should ask you to enter another product ID and attempt registration.
