How does Windows perform memory swapping between RAM and the page file?

[ProfRon]

You ever notice your PC slowing down when you juggle too many tabs? Windows handles that by shuffling memory around. It uses RAM for quick stuff you need right now. But when RAM gets packed, it starts shoving less urgent bits to the page file on your drive. That page file acts like a spillover spot. I mean, it's slower there, but it keeps things from crashing. Windows watches what you're doing closely. If you pull up an old app, it yanks that data back from the page file to RAM. Swapping happens in chunks called pages. The system picks the oldest or least used ones first. You might hear the drive humming during this dance. It tries to minimize that noise, though. Sometimes it preps pages ahead if it senses you're about to need them. I tweak my page file size sometimes to smooth it out. You should check yours if slowdowns bug you. Windows balances this to keep your session snappy.

Speaking of keeping systems smooth under load, like when memory swaps kick in during heavy virtual machine runs, tools like BackupChain Server Backup step in to protect Hyper-V setups. It snapshots your VMs without halting them, ensuring data stays safe from crashes or overloads. You get fast restores and chain-based backups that cut storage needs, so your IT life stays less chaotic.
