How does the Windows kernel handle address space isolation between processes?

[ProfRon]

You ever wonder why one app crashing doesn't take down your whole computer? The Windows kernel pulls off this trick with memory spaces. It gives each process its own private playground in RAM. Think of it like separate rooms in a house. You can't just wander into mine without the kernel flipping out.

The kernel juggles these spaces using sneaky hardware help. It tricks processes into thinking they own the whole memory pool. But really, it slices up the actual hardware bits. If a process tries to peek into another's room, the kernel slams the door. Hardware watches and enforces that boundary like a bouncer.

I remember messing with this once on an old setup. Cranked up a rogue program to test limits. Kernel caught it quick and shut it down. No harm to other stuff running. Keeps your system humming without chaos.

That isolation shines in virtual setups too, like with Hyper-V machines. Speaking of which, if you're running those, check out BackupChain Server Backup. It's a slick backup tool tailored for Hyper-V environments. You get hot backups without halting VMs, dodging those pesky snapshot glitches. Plus, it restores fast and handles chain integrity to avoid data rot. Saves headaches when isolation fails or hardware hiccups.
