@Andy and the rest:
Check this before installing:

1) VirtualBox with Windows 7 as profile?
2) Configured with IO ACPI, VT, Nested Paging, 3d acceleration

If both Checked then check:

3) Does your PC have Intel VT?

If all are yes then it should work, if the last one is no, you are out of luck, since the 3) is needed.

@methodbeat:
It is Pre-Milestone 3...

Milestone 3 began just 1 build higher.

Ah I'm out of look using my home server then, no VT. Only has MMX, SSE(1,2,3,3S) and EM64T. I'll use my desktop later.

Just as with Windows Vista and 7, you have to boot into Safe Mode to install the Guest Additions; otherwise, Windows File Protection interferes.

I have it installed on a *spare* hard drive in a dual-boot with 7 x64 and it's plenty fast enough (faster than either Windows 7 SP1 (7601) or 7850, despite the slower SATA HDD). The quibbles are expected - some issues with IE 9 and add-ins/plug-ins therefore, Norton 360 overzealously eats two files critical to 7955's changed networking stack (I switched to Avast 6 due to that - MSE won't install due to the OS itself being too different). ISOs (in addition to VHDs) mount directly (so much for virtual-disk/drive utilities, such as VirtualCloneDrive or Daemon Tools) - this is something that even 7601 doesn't do. You can burn ISOs directly, but not mount them, in 7601.

After a few bad installs, I got this working in VBox 4.0.4, with 2.3GB RAM 128MB graphics and the "Intel PRO MT Desktop" for my network connections, the PCNet network adaptors for some reason would not work with me

also got Red-pill working and unlocked the pattern logon




I haven't tried any of the other features yet

That horrible oompa loompa thing in the lockscreen is so ugly and disgusting I had to turn the ctrl-alt-del logon off, I couldn't bear to look at it any longer...

I wish there was a way to change it..

Ah i thing there is no BSOD screen because the setup failed in VmWare, and when the virtual pc restarts, it says: You computer needs to restart.
Here something what i forgot.
Error code: 0x00000005c

Whatever you try to do on VMware for M2, it wont' work, just do it on VirtualBox.

I will try 7955 once i can get it. Once i can get the red pill, i will fully enjoy this build.

use the redpill and instructions from here. Everything work on my box without FC's. hope this helps.

Seems BetaArchive is pretty popular right now. Slashdot linked to a ComputerWorld article which linked to this topic.

Think I'll give it a test run.

Does anyone have the problem of mouse slowness and any solution to fix? Thanks!

hmm no. scroll speed is as good as my win 7. i haven't seen any lag. are you using a wireless or Bluetooth mouse? if so try adjusting your dpi settings.

hope this helps.

its because it uses software rendering for aero which uses a lot of cpu.
if you Control-Shift-F9 to turn it off, then it is full speed again.
You can still get some elements of aero lite with it

(Had this trouble on my old pentium 933 with 512mb ram i tried it on with a ati rage pro graphics card.

Thank you baap786 and jamieostrich, will try both solution later.

i have this build i downloaded the redpill and bluepoison unlocked everything but the reader is having tech probs and the new disk clean tool is gone and wont unlock

When red pill will work without crashing other Windows 8 feautures?

Thanks for the post! Looking forward to getting my FTP access and trying it out.

no crashes here with the red-pill.

Is Hybrid boot still present? It still works on shutdown as it booted quite faster than Windows 7, but I can't find the option in Power Settings.

ive used the red-pill, but i cant find/enable some features:
-login patern
-alternative ctrl-alt-del screen (the ugly guy and the blue one, with the clock).

the get the new oobe can i just use sysprep in win8?

yep! under what the power buttons do for some reason though!

Windows 8 is working fine for me, dual boot on my laptop. Redpilled fine, only thing not working is that firefox keeps crashing for some reason. Anyone else having this problem?

yea having the same problem. it only happens on some sites. sad thing is flash videos with audio works fine on firefox and chrome which doesn't crash doesnt work well with flash. it plays the video but doesn't output the sound.

ie9 works like a charm though

I was reading that microsoft said they will be taking criminal action against people using this.. So we could be facing court?

Most probably a delebrate leak from microsoft
