From the Store entry:
Sysinternals Suite is a bundle of the Sysinternals utilities including Process Explorer, Process Monitor, Sysmon, Autoruns, ProcDump, all of the PsTools, and many more.
The Sysinternals website was created in 1996 by Mark Russinovich to host his advanced system utilities and technical information. Whether you’re an IT pro or a developer, you’ll find Sysinternals utilities to help you manage, troubleshoot, and diagnose your Windows systems and applications.
The suite includes AccessChk, AccessEnum, ADExplorer, ADInsight, ADRestore, Autologon, Autoruns, BGInfo, CacheSet, ClockRes, Contig, Coreinfo, CPU Stress, DebugView, Desktops, Disk2vhd, DiskExt, DiskMon, DiskView, DU (Disk Usage), EFSDump, FindLinks, Handle, Hex2dec, Junction, ListDLLs, LiveKd, LoadOrder, LogonSessions, MoveFile, NotMyFault, NTFSInfo, PendMoves, PipeList, ProcDump, Process Explorer, Process Monitor, PsExec, PsFile, PsGetSid, PsInfo, PsKill, PsList, PsLoggedOn, PsLogList, PsPasswd, PsPing, PsService, PsShutdown, PsSuspend, RamMap, RDCMan, RegDelNull, Regjump, RU (Registry Usage), SDelete, ShareEnum, ShellRunas, Sigcheck, Streams, Strings, Sync, Sysmon, TCPView, Testlimit, VMMap, VolumeID, WhoIs, WinObj, and ZoomIt.
Most of the tool names are self explanatory - some have graphical UIs, some don't, depending on the need. But you only need to run the ones you're interested in. Process Explorer (screenshotted above) is an obvious one, for example.
It's not entirely clear what will happen if the suite is updated in the Store, but I'm guessing it will show as an update in the usual way.
These .EXE tools should run on any x86-based PC - so almost everything, though obviously we have ARM-based PCs starting to appear in the real world.
