Windows Repair Toolbox 188.8.131.52 + Portable | 3.6/4.1 Mb
Windows Repair Toolbox includes most third-party applications and Windows utilities you might need to repair any Windows problems in one small application. Its broken down into categories for Tools, Malware Removal, Tests, Notes, and Settings. When required, the program will download what it needs and can also optionally run many tools in unattended mode. Of course, you can download any of these tools individually or another similar ISO based third-party program, but those are only as good as their updates. Since this downloads directly from the homepage, you always have the latest version and only what you need.
Another huge advantage any tech will appreciate is the links to Windows utilities including chkdsk, MSConfig, Regedit and much more. Sometimes you get stuck when on a repair job and seeing one of these tools might just jog your memory. If there is one complaint it’s that there are some tools I would add and some tools I would remove, but that’s mostly personal choice, so I see no problem getting the job done with most issues with the tools he has chosen.
Of course, he knows you can't please everyone so he even uses the tagline "(Almost) everything you need to repair Windows problems in one small handy tool." If you need to repair a computer you’ll be hard-pressed to find a better way to bring and execute the tools you need this efficiently. It is available as an installer and portable application.
