Clean up the Windows Installer folder

When applications are installed on your PC using Windows Installer, the setup program and patch files are added to a hidden \Windows\Installer folder. These are used later whenever you need to modify, update or uninstall the software.

These files should be removed automatically when software is completely uninstalled, but this doesn't always happen. Some PCs may have many orphaned files taking up gigabytes of drive space.

PatchCleaner is a free tool which scans your Windows Installer folder for redundant items. Essentially it uses WMI to obtain the official list of installers and patches, assumes all those files are required, and highlights everything else as "orphaned".

By default the program will move the files to another folder, rather than delete them. We would recommend you keep that setting, so you can copy files back if they turn out to be necessary after all.

Once you've set up the "Move" folder, PatchCleaner is very straightforward. Run it, check the list of orphaned files (if any), click a button to move them and you're done.

We tried the program on a Windows 10 laptop, where it recovered 312MB with no apparent issues. That's not huge, but still worth having, especially as it's a gain you won't see with more conventional disk cleanup tools.


A simple way to recover (potentially) large amounts of drive space. Make sure you move the files rather than delete them, though, so you can easily copy them back if PatchCleaner accidentally deletes something important.

WhatsApp Messenger 2.19.20

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.19.20 

• You can now reply to a group message privately in your 1:1 chat. Tap and hold a message in a group chat and select "More", then "Reply Privately".
• When editing a photo or video, you can tap the smiley icon to add stickers. 
• From the Status tab, you can now 3D touch to preview a contact's status.
