Windows 10/Server screen freezes

Whenever i use windows 10 or windows server the screen just freezes, it happens all the time that basically i cant work with it, i already tried different configurations, the features thing from windows but nothing seems to work, the only way to unfreeze the screen is clicking the red cross and then exit that menu(the menu that ask if you want to save the state, shut down the machine...), but that only works for another minute and then again the screen freezes.
Anyone has a solution?

My audio is extremely crackly, and the game I'm playing is really laggy on top of that.

I'm trying to play Operation Krabby Patty, but the audio is awful, and the game is crazy laggy.

Emulated operating system: Windows XP 64-bit

My operating system: Windows 11 64-bit

Guest additions installed: Yes, host extensions no

VirtualBox version: 7.2.20

I've tried looking for 3D acceleration and swapping my audio device to Intel HD Audio, but I haven't been able to find either of those settings.

VirtualBox Windows 10 VM has extremely slow downloads (0.41 Mbps) but fast uploads (29.50 Mbps) — tried everything for 3 days

Hi everyone,

I'm struggling with an extremely slow internet download speed inside my **Windows 10 VM running on VirtualBox**. It's been 3 days, and I've tried multiple fixes without success.

**Speed test results inside the VM:**

- Ping: 9 ms

- Download: 0.41 Mbps

- Upload: 29.50 Mbps

**What I've tried so far:**

- Switching network adapter types, including Intel PRO/1000 MT Desktop and Server.

- Resetting the Windows network stack through Command Prompt.

- Performing a shallow Git clone.

- Increasing Git's `http.postBuffer` size.

- Several other troubleshooting steps that I can no longer remember.

Despite everything, downloads remain painfully slow, while uploads are relatively fast.

I'd really appreciate any suggestions for diagnosing and fixing this. I'm exhausted from troubleshooting and would be grateful for a solution.

Thanks in advance!

Need help with a vm

Hey, I’m trying to play an old childhood game of mine called Horse Museum (SSO) again, and I’m trying to get it running in a VM on Windows 11. I’ve never really used virtual machines before, so I’m a bit lost. So far I’ve installed VirtualBox, I have an AMD Ryzen 7, and I had to enable SVM Mode in my BIOS because virtualization was disabled. It’s enabled now and shows as enabled in Task Manager. I also started creating a new VM in VirtualBox and selected Windows 10 (64-bit), but I don’t actually have a Windows 10 ISO yet. I’m not sure which Windows version I should use for Horse Museum or where to go from here with setting up the VM. Could someone please explain to me what I need to do step by step? I’d really appreciate the help, I just want to be able to play this old childhood game again, if u want to help a girl out add me on dc: subpupeater or just comment

Failed to open VBOX (Nvram unsupported_format)

Hello I have 7.2.0 r 170228 (Qt 6.8.0 on windows) Virtual box. One of my machines (rest are working well) is sudenly unable to open giving me this error communicate : Failed to load the NVRAM store from the file (VERR_VFS_UNSUPPORTED_FORMAT). Have done a copy of this VM folder, I have money there so I can't affor myself to lose it. Got any ideas how to run it? Found that solution saying that I should replace NVRAM file : https://forum.manjaro.org/t/win11-guest-created-with-6-x-virtualbox-no-longer-booting-on-7-x/131563/9 but cannot follow it, when I created new machine there's no NVRAM file in file explorer there so I can't just copy and replace it. Im very novice in VBOX and computer terms so every help will be very appreciated :) Tried repair it with chat gpt but it just wasted my time..
