I am really impressed with this portable tech toolbox called Windows Repair Toolbox (see source link below); and, can see it as a real asset to anyone who assists others that are experiencing computer problems.
The developer has created a dashboard of sorts that will assist you with downloading the necessary tools to fix or troubleshoot a PC. Most of the downloaded tools will land in a downloads folder that is a subfolder of the Windows Repair Toolbox folder (which keeps everything together in one place). There are some downloads that are full downloads (for example, Malwarebytes Anti-Malware). Another nice feature is that you can add your own custom tools.
(Almost) everything you need to repair Windows problems in one small handy tool.
