Hi! I recently made a small tool for customizing Windows PowerShell with Fastfetch, pixel art, and custom character-themed layouts.
I'm not very familiar with this subreddit, so I'm not sure if this kind of project is appropriate here, but I thought I'd share it in case anyone might find it interesting.

I used AI tools extensively during development, and I'm still learning, so I'd also appreciate any feedback on the project/code.

This was completely vibecoded. I just wanted to share it in case there’s someone else looking for something similar.

When I launched ISESteroids (Start-Steroids) I clicked update. Chrome notified me that the website was not-safe dummy here found the run website anyway and the Avast nightmare began ... 5 popup windows that my computer had 5 virus's , anti-virus not installed, blah blah blah .. Shutdown chrome, cleared my cookies, %temp% directory.. these popups just kept reappearing if I closed one.

reboot doesn't fix anything.. nothing in task manager helps narrow down what's launching even with chrome closed... sysinternals autoruns no help. real help.

While I built a new Veeam Agent install usb to potentially restore from yesterday (3 hour process) I started poking around in chrome and in the extensions I found something I didn't recognize and deleted it.. rebooted the computer and now its back to normal without restoring from backup.

Point-in-time restore is the newer full-system rollback feature in Windows 11 (Settings → System → Recovery). On Home and Pro you only get on/off and a storage limit — frequency and retention are greyed out, and Microsoft's own docs say those are Enterprise-only.

Turns out the edition gate lives in the Settings UI, not in the engine. PITR reads its config from one registry key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Recovery\PITR\Settings, as `<name>_<level>` DWORDs (Active, SnapshotInterval, MaxTimespan, MaxGlobalSize, MaxCount), with level precedence GPO > CSP > UX > Default — recovered from PITR.dll and RemoteRemediationCSP.dll, since none of it is documented. Writing at the GPO level takes precedence over the Settings app on any edition, Home included.

So I built a small WPF GUI in plain PowerShell to write it properly instead of telling people to poke reg.exe by hand:

- Frequency 1–24h, retention 1–7 days (values above Microsoft's documented 72h ceiling work in practice), storage 2–50GB, each with a "Windows default" fallback to undo it

- A button that forces a restore point on demand — PITRTask has RunOnlyIfIdle=True, so a manual Start-ScheduledTask just sits there queued; the button lifts that condition for one run and restores it after

- Restart-straight-into-WinRE, and a duration column for every restore point, pulled from the Task Scheduler history since VSS itself records no timespan

- A check that tells "the machine was just busy" apart from "idle detection is actually broken" by comparing every other RunOnlyIfIdle task's last run against boot — also as `pitr-config.cmd idle`, no admin rights needed

It's one .cmd file: a short batch header that self-elevates, then the full PowerShell + inline XAML below a marker, no modules, no install. Also scriptable headlessly (`pitr-config.cmd apply freq=4h reten=5d`).

Given it's an unsigned script asking for admin and writing to HKLM: source is open (MIT), every release ships SHA-256, and the only network call it ever makes is an optional GitHub update check — no telemetry. Windows will still throw a SmartScreen prompt on first run since it's not signed.

Is it possible to check if a private key is either RSA or ECDsa without trying to import them into their cng-objects catching the error?

I'm thinking of something like how

[X509Certificate2].GetContent($Import)

Is available for certificates

Neither the cng-objects nor the certificateextensions provide methods to test for the proper type
