The Electric Sheep App is one of the best freeware applications available for Windows PCs. It has all the features of Windows XP, such as sharing files among all users on a network, file backup and search, etc. In order to get it, you will need to get the free trial. The only thing about this application is that you cannot download it directly from the developer, but it can be downloaded by downloading it from a special website. The free version is limited to 30 days, after which the full version will be purchased. This might be a good idea if you are interested in trying out the application before buying it. There are a few drawbacks that come with it though.
The first drawback is that there is no option for saving your work, except for the trial, and you will have to start over when you want to save a previous session. Secondly, there is no time limit. It will automatically delete itself after some time. Thirdly, it doesn't have any type of support. If you encounter any problem with the application, you will have to contact the developer and wait for their reply. Last but not least, the connection between your computer and the server of the developer is slow, and this can be a problem if you are trying to download large files.
Once you use the free version for a while, it is likely that you will want to upgrade to the full version. Fortunately, there is a way to upgrade. The software can be upgraded by sending a "PayPal payment request" and the developer will then send the new version to you. If you want to upgrade to the full version, you will have to send them another PayPal payment request.
