SyMenu allows you to download utilities from NirSoft, SysInternals and more. Download the program from here and check the programs you want.
Once you download the programs, you can use SyMenu to run the many programs (over 1200) from a flashdrive. To exit the program, you will need to scroll to the bottom and select exit.
In order to start in an elevated mode (Administrator), use the Symenu.Admin.exe. You will see a small icon adjacent to running programs and the time on the right side of the taskbar. Double click to run SyMenu.
Note: Some files may identify as viruses or malware. These are false positives because of what they do. Make exceptions for these programs.
