1. Sysinterals Suite

2. Wireshark – Protocol Analyzer

Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, in May 2006 the project was renamed Wireshark.


3. Treesize – Diskspace Management

TreeSize Professional is a powerful and flexible hard disk space manager for Windows 8/7/Vista/XP or Windows Server 2012/2008/2003 (32 or 64 Bit). There’s a freeware version with some limitations. It’s not possible to scan remote disks and it’s not supported on the Windows Server platform. If you want all this, you’ll have to buy the professional edition which is in my opinion worth it.


4. Rufus – Create bootable USB drives 

Rufus is an utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. It’s a very fast and lightweight utility.


5. Dependency Walker – Windows Module Analyzer

For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

Dependency Walker is also very useful for troubleshooting system errors related to loading and executing modules. Dependency Walker detects many common application problems such as missing modules, invalid modules, import/export mismatches, circular dependency errors, mismatched machine types of modules, and module initialization failures.
