Yes, form the user perspective it does the same thing, it works a little bit different however as it doesn't replace system files and instead injects custom extending files into processes. And is available for Vista and 7, instead of just Vista as the original extended kernel was

Reserved

So it worked initially?, what was it set to? DXVA2(native) or none ? LAV settings can also be accessed from the start menu, K-Lite Codec Pack\Configuration There will likely be 2 one for mpchc and one system-wide, set both to whatever worked, if settings crash, redo k-lite codec pack setup and configure those options during setup Test dreamscene Some applications may not respect LAV configuration settings, in that situation you will usually have to remove DXVA2-related dlls installed by the graphics driver so they will have no chance to use something broken, I'd done this once with AMD drivers The fact that symptoms are the same between AMD and NVIDIA gpus however makes me think that you have a conflicting other application/driver installed as these are all old vista-supported gpus not something that needs custom drivers EDIT: And did you uninstall AMD drivers with DDU before installing nvidia? (latest for vista - DDU v18.0.4.6.exe)

So now that you have the codec pack, launch MPC-HC that got installed with it and try to play a h264 test video https://test-videos.co.uk/bigbuckbunny/mp4-h264 launch LAV splitter video settings - the red icon in the system tray, there is a "Hardware Decoder to use:" in the top middle, test various hardware decoders and check which do and don't work, make sure H.264 is checked under codecs for HW

For dreamscene try installing K-Lite Codec Pack 16.6.5 (I believe someone reported some issues with a later version) Edit, this post: https://msfn.org/board/topic/175262-last-versions-of-software-for-windows-vista-and-windows-server-2008/page/66/#comment-1214028 Is explorer.exe still crashing, if not I think it's Camtasia's own problems at this point

Is any of the extended kernel-like stuff installed?

Is directx_Jun2010_redist installed? Windows 7 doesn't use dx9 on desktop (maybe Camtasia uses dx11 on Win7 too), check if directX9 works there with any directX 9 game, look up games you happen to have on pcgamingwiki

Here's a copy paste of a report with my experiences with this advapi32.dll patch, until now being on win32's patreon it was probably also "members only" : I was probably the first user testing it, there were no comments before. That's how it was before: Tons of services failing to start, UAC being super-annoying, USB drivers that used to BSOD the system, with the patch don't

To verify which timer is in use, get falco PhenomII Tweaker and run TimerCheck.exe, not the tweaker's main exe Read the value right on the top called QPC freq: PM Timer = 3.579545 Mhz HPET *classic* = 14.31818 MHz HPET new Intel = 19.200000 Mhz TSC = On Win7+ = CPU_BASE_FREQ/1024, On WinXP = CPU_BASE_FREQ, On Win10 1803+ = usually upscalled to 100MHz

On the LSC patreon site, there is a patcher that edits advapi32.dll from your system, there are also instructions on how to patch it manually. The access to it available only to paid subscribers of the Supermium support, however the patcher itself contains no DRM-like elements https://www.patreon.com/win32 Modern motherboards have no setting to disable HPET, you could modify the BIOS, or I've heard you could disable it when you load Windows using GRUB, myself I've tried neither of those methods yet. Windows 7 and up don't use it by default on modern (Nehalem and up I think) systems except from time to time to resync. Vista does use it as the main timer https://learn.microsoft.com/en-us/windows/win32/sysinfo/acquiring-high-resolution-time-stamps Also Windows 7 and newer accept bcdedit entries that control which timer is in use: https://sites.google.com/view/melodystweaks/misconceptions-about-timers-hpet-tsc-pmt#h.bbv7ue62w883 Vista does not. With equal timers used, yes, with a modern Intel HPET that is 5 times slower than it used to be, it loses to systems that are able to utilize TSC. EDIT: Now I ran this benchmark again on Ivy-bridge and it mostly takes like 700-800 ns, so maybe it's only 3 times slower but still

I've made some benchmarks comparing TSC vs. HPET timers impact for CPU's gaming performance and spoiler: it matters quite a bit. First a little bit of history/background: PM Timer (ACPI Power Management timer) is a high-latency timer used in Windows 2000 days, it clocks at 3.579545 Mhz TSC is a low-latency timer on the CPU, originally, it clocked at the same freq as the CPU, it is used by Windows XP by default So when CPUs started downclocking to save power TSC would also downclock, that's why with Vista Microsoft opted for: HPET is a high-latency timer on the motherboard, used by Windows Vista, it clocks at for example 14.31818 MHz on Ivy-Bridge and 19.200000 Mhz on Alder Lake, it is unstable on newer Intel platforms. Vista fallbacks to PM timer when HPET is not available Invariant TSC is a TSC (low-latency) that always clocks at the CPU's base freq regardless of whether it pawer-saves or turboes, it is used by Windows 7+, but Windows XP can use it too as it would an old-school TSC. On older platforms where TSC is not invariant Windows 7 uses HPET just like Vista Windows 7 still uses HPET to sync TSC from time to time, but XP can still work stable on newer system without it so Vista should also be able to if forced to use TSC. Benchmarks were performed on 12th gen Alder Lake i5-12600, DDR5-4800MT/s, NVIDIA 3090 Windows 10 has all of it's new security mitigations that impact performance disabled, all systems are debloated, all systems have Meltdown/Spectre patches disabled/ not applited, BIOS patch that allows Vista and 7 to properly use turbo on Alder Lake is applied The benchmark was Cinebench R15 OpenGL, with a 3090 this benchmark is almost exclusively CPU-bottlenecked Here are the results (a median run out of 3 for each config), lowest to highest 215.15 FPS - Windows 10 HPET 221.91 FPS - Windows 8.0 HPET 234.92 FPS - Windows Vista HPET 242.84 FPS - Windows 10 TSC 257.58 FPS - Windows 8.0 TSC Vista TSC is dnf cause I don't know of any way to force it to use it, the code could still be there left from XP times. Vista HPET on ivy-bridge usually scores higher than 10 TSC, but lower than Windows 7 TSC, Windows 8.0 TSC also wins there being marginally better than 7, but I don't have all of those system installed on ivy-bridge to provide a benchmark right now, and these are results I remember from back when I did This make's sense since when I run falco PhenomII Tweaker's Timer Check (Tweaker is only for AMD PhenomII, but timer check is universal), it runs a benchmark of running 1 Million QueryPerformanceCounter calls. On Alder Lake it takes 2243ms, whiles on Ivy-bridge around 750ms, So Intel's new HPET is around 3 times slower than the old one Now, after @win32 created his new patch for Haswell+ Vista instability Vista is now very much usable on 12th gen Intel - there is absolutely 0 serious crashes but the stability is not yet perfect - 3 services and startup programs still sometimes fail to start. So the question is obviously how to force TSC on Vista for improved stability and performance?

/s is the destination (in MBR disk S: should be active partition) Yes - it should be the C:\Windows of the windows installation that you want to add to the bootloader Based on my limited knowledge of GPT (and this alligns with what @Tripredacus said) there is no such thing as active partition for GPT disk Instead you may have to (or maybe this will be done automatically) make a FAT32 efi partition instead, but I don't know the details about that cause I don't have much experience with GPT disks, so look that up

Incompatibilities with Vista Extended Kernel Running both: Extended Kernel and Second System works mostly ok, but there are some incompatibilities so it may not be that good of an idea? In the following months I'm gonna be testing ExK + SeSy vs SeSy only and hopefully draw some conclusions To disable Second System right click on the program's exe and select Disable Second System Don't work at all VLC Media Player - "application was not properly initialized" - Tested by @TSNH on Windows Vista Oct.2022 x64 ExK There are some issues Sysinternals Process Explorer 17.06 - On Vista ExK + SeSy sometimes launches sometimes not, same behavior as when ExK is used to provide compatibility)

Forgot to quote you so you can get a notification as it's been a while Also commenting on the discussion from reddit The 7z contents from "this one" is the same as the originally posted one, I've binary compared them with winmerge And they are discussing nvme, but this pack contains also Generic_USB3x_6.2.9200.21180

Usually, the best universal USB3 drivers are pored 8.0 ones by @George King Someone links to that on reddit https://old.reddit.com/r/WindowsVista/comments/19e1bxn/finally_got_vista_to_run_on_nvme_look_on_my_works/ Right now the working link is the one under "this one" However on AMD systems that are 2015 or earlier it's better to use AMD drivers meant for Windows 7, they work for Vista too.

I have a 120Hz monitor and while games are indeed smoother than with 60FPS, On Windows 8, 7, and Vista, Aero animations still feel limited to 60FPS. Is it possible to make them actually utilize high refresh rate? or maybe make them 2x faster and increase their FPS that way?

My iso had a different file version, I think I got the right one by extracting files from updates of some windows vista update pack, but I don't remember which one, Searching this version also brings some results, you can try downloading this version directly from the internet if you don't have time for scavenging from unpacked updates (may be less safe tho) And it didn't work anyway on the laptop that I tried this patch on, your mileage may vary

The patch that you are referring to https://www.wincert.net/forum/topic/18176-vistaw2k8-x64-on-modern-hardware/ has to be applied to this exact version of acpi.sys 6.0.6002.24312 (vistasp2_ldr_escrow.180308-1636) make sure you have the right version But the necessary patch can be different for various hardware platforms

If you have K-Lite codec pack and mostly deafult settings, audio dithering for 16-bit output is enabled in the LAV audio decoder and it's settings. This process alters the sound slightly to reduce noise level So the possible reason why WAV can sound different than flac is because flac goes through the LAV audio and respects it's default settings with dithering (can be changed) and WAV by default doesn't go through the LAV audio and a standard builtin Windows decoder is used instead because wav is a Windows-native format and therefore the dithering setting is not being applied, so the output sounds different despite inputs being the same and lossless.

Update: Larian Studios has dropped a new update to BG3! I've just updated this guide with a new workaround regarding the Win7-incompatible PlayFAB component. According to the developers it's the last main development update so there is a big chance that BG3 will be kept compatible with Windows 7 for years to come

If so an FTP server on a local network will probably be the easiest transfer method. As a server you can use an old phone or ISS on a Windows virtual machine (even NT4 server would work)

Does it show up at all in My Computer when you connect it and allow photo transfer on the phone's screen or this error pops up when you initiate the transfer? I was able to test on an older iPhone (not 15pro) but updated to IOS 18 and Windows Vista and photo transfer worked there without any iTunes.

As a bonus here are Vista-compatible .reg files that add PowerShell 7 to the context menus To use them copy, save a .reg and apply Open PowerShell here: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\openpwsh] "MUIVerb"="&Open PowerShell" "Icon"="C:\\Program Files\\PowerShell\\7\\pwsh.exe" [HKEY_CLASSES_ROOT\Directory\Background\shell\openpwsh\command] @="cmd.exe /k for /l %%i in (0,0,1) do cls & pwsh.exe -NoExit -RemoveWorkingDirectoryTrailingCharacter -WorkingDirectory \"%V!\" -Command \"$host.UI.RawUI.WindowTitle = 'PowerShell 7 (x64)'\" " Open a folder in PowerShell: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\shell\PowerShell7x64] "MUIVerb"="&Open in PowerShell" "Icon"="C:\\Program Files\\PowerShell\\7\\pwsh.exe" [HKEY_CLASSES_ROOT\Directory\shell\PowerShell7x64\command] @="cmd.exe /k for /l %%i in (0,0,1) do cls & pwsh.exe -NoExit -RemoveWorkingDirectoryTrailingCharacter -WorkingDirectory \"%V!\" -Command \"$host.UI.RawUI.WindowTitle = 'PowerShell 7 (x64)'\" " Run .ps1 file in PowerShell: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\PowerShell7x64] "Icon"="C:\\Program Files\\PowerShell\\7\\pwsh.exe" "MUIVerb"="Run with PowerShell 7" [HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\PowerShell7x64\Command] @="cmd /k for /l %%i in (0,0,1) do cls & pwsh.exe -Command \"$host.UI.RawUI.WindowTitle = 'PowerShell 7 (x64)'; if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'\" " As you can see they try to retry the PowerShell launch if it fails to overcome 7.2.2's bug, and are also in a bit different format than those supplied with PowerShell installer because those didn't work with Vista. I still haven't figured out how to make run as administrator versions EDIT: Changed command logic so that the should now work for much longer directory path strings.
