You can never predict when your PC will crash – Windows can be quite finicky at times. That's why it's always useful to have a small store of programs on a flash drive to help troubleshoot problems. Howtogeek.com portal shared four programs every Windows user should carry with them.

Internal system
The Sysinternals utility suite is probably familiar to anyone who has ever performed Windows diagnostics. It was initially created by third-party developers, but later Microsoft acquired their project. It is basically a collection of tools that allow you to look deeper into system information. For example, Process Explorer is an enhanced version of Task Manager that not only shows active programs but also all the resources they use. Autoruns allows you to monitor automatically running services and applications, while Process Monitor monitors changes made by processes in real time.
Everything
Everything is an indispensable tool for searching hard drives. Although Windows' built-in search feature is better than before, it's still slow and resource-hungry. Everything quickly builds an index of files and paths, allowing you to find the desired item almost instantly. The utility runs database latency or background indexing.
HWiNFO
If Sysinternals is suitable for diagnosing applications, processes and the operating system itself, HWiNFO allows you to study the status of PC components: from fan speed to voltage, temperature and RAM consumption. For example, using this utility you can check if your PC is overheating and if the processor is overclocked correctly and if the RAM is working properly.
CrystalDiskInfo
Anyone who has owned a computer for a long time has probably encountered a hard drive error at least once – perhaps one of the most annoying problems on Windows. It starts small: files take longer to open, the system closes more slowly, the operating system sometimes crashes… But if you don't notice an impending problem in time, you can lose a lot of valuable data. This is where CrystalDiskInfo, a drive health diagnostic tool, can help. It will tell you what condition the hard drive is in, whether it is overheating or whether an error occurred when reading data.
