Windows 365 Reserve: Because Your Shitbox Thin Client Can’t Handle The Cloud AND Reality Simultaneously

Oh look, another brilliant fucking idea from Microsoft. Let’s take a perfectly good computer—well, okay, a repurposed piece of shit that used to run Windows 7 until Gary from Accounting spilled coffee on it—and turn it into a “Windows 365 Boot device.” Because apparently booting into a local OS like a normal human being is too fucking simple for 2024. No, we need to boot straight into a Cloud PC, because nothing says “enterprise efficiency” like adding 47 layers of network latency between the user and their fucking spreadsheet.

But here’s the kicker, you witless fucking muppets: when you boot into this cloudy nightmare, Windows 365 helpfully consumes every single goddamn resource your potato-grade thin client possesses. RAM? Gone. CPU? Maxed out. The local OS? Reduced to a stuttering, dribbling mess that makes Windows Vista look like a fucking Cray supercomputer. Users are sitting there trying to open Notepad locally while the Cloud PC is busy downloading the entire Internet, and suddenly the machine locks up harder than a politician’s conscience during an ethics hearing.

Enter Windows 365 Reserve—the digital equivalent of putting a fence around your lunch so the fat kid doesn’t eat it. This feature lets you reserve CPU cores and RAM specifically for the local device, ensuring the Cloud PC can’t hog everything like a greedy little shit. Microsoft recommends—get this—a minimum of 2GB RAM and 1 CPU core for the local OS. That’s right, you need to reserve resources just to keep the base OS from suffocating. It’s like buying a car and having to reserve one wheel just to make sure you can actually steer the fucking thing while the Cloud PC takes the other three.

You can configure this horseshit through the Settings app (if you hate yourself) or via Intune CSPs (if you’re a masochist with a death wish and a Microsoft certification). Set your RAM allocation in gigabytes—whole numbers only, because decimal places are apparently too complex for this godforsaken platform—and CPU cores in, well, cores. You can even lock the settings so users can’t fuck with them, which is honestly the first intelligent thing I’ve heard about this entire clusterfuck of a feature.

Is it in preview? Of course it fucking is. Nothing says “production-ready” like slapping a beta tag on critical resource management and throwing it at enterprise customers who are already hemorrhaging money on Azure subscriptions. But hey, at least now when your boss asks why the thin clients are running like molasses in January, you can pretend you knew about resource reservation all along, instead of admitting you just followed some shitty tutorial from a tech blog written by someone who actually reads release notes.

Anecdote: Back when I was still touching physical hardware with my own hands—a horror I wouldn’t wish on my worst enemy—I had a user who insisted his physical workstation was “too slow” and demanded we migrate him to a “Cloud PC” because he read in some shitty in-flight magazine that “the cloud is infinitely faster.” So I set him up with a thin client—a cast-off piece of garbage with 4GB RAM that I pulled from the e-waste pile and wiped the mold off. I “forgot” to enable resource reservation. Three days later he calls me, screaming that he can’t even open Calculator locally while his Cloud PC was “thinking” about loading Outlook. I told him that’s just how the future feels—distant, slow, and utterly disappointing, much like his career. Then I “accidentally” tripped over the power cable while “fixing” his desk. Funny how “cloud computing” looks exactly like a black screen when there’s no fucking power. He went back to a proper PC the next day.
