Как известно, виртуализация бывает разной.
Компания Microsoft выделяет следующие виды виртуализации:
1. Datacenter virtualization.
Решением в этой области является роль сервера Windows Server 2008 R2 Hyper-V или Hyper-V Windows Server 2008 R2.
2. Client virtualization.
Решением в этой области являются Remote Desktop Services в Windows Server 2008 R2, Microsoft Virtual Desktop Infrastructure, Microsoft Enterprise Desktop Virtualization, Microsoft Application Virtualization, Windows Virtual PS и, наконец, Windows XP Mode.
3. Cloud virtualization.
К чему бы это я? А к тому, что некоторые решения незаслуженно забыли, сконцентрировав все свое внимание на виртуализации серверов и VDI, ну еще быть может RDS.
Что, например, делать, если в компании поменялся корпоративный стандарт и теперь стандартом является не Windows XP, а Windows 7? При этом программисты не успели переписать свое ПО, которое «заточено» под устаревающие операционные системы.
Конечно, можно закупить ферму серверов, внедрить VDI и раздать виртуальные машины пользователям – вопрос денег. А если их не так много?
Одним из решением является использование Windows XP Mode, который позволяет, используя локальную виртуальную машину под управлением Windows XP с установленным специфичным ПО, опубликовать в среде Windows 7 это приложение так, как будто бы оно установлено не в виртуальной машине.
В этом случае последовательность действий следующая – сохраняем пользовательские данные, переустанавливаем ОС Windows 7, включаем Windows XP Mode, в запущенной виртуальной машине устанавливаем ПО и публикуем наружу. Долго? А то
А если таких машин 100 или 200, или 1000? Можно отпустить усы и бороду 
Хорошо, упростим – у вас установлен продукт Microsoft System Center Configuration Manager с Microsoft Deployment Toolkit. Эти средства предназначены для управления рабочими станциями и серверами, особо выделяем модуль Operating System Deployment, который позволяет централизованно разливать ОС на новые рабочие станции, или переустанавливать ОС на уже работающих станциях. С недавнего времени совместное использование этих продуктов позволяет полностью автоматизировать процесс миграции предприятия на новую ОС Windows 7.
А для тех предприятий, у которых куплен Software Assurance есть еще один дополнительный бонус – новый продукт от Microsoft – P2V Migration for Software Assurance (основанный на Sysinternals Disk2VHD). Он позволяет в процессе автоматизированной миграции на Windows 7 создавать виртуальную машину из существующей под управлением Windows XP или позднее, запускать ее в режиме Windows XP Mode и публиковать установленные приложения и Internet Explorer в среде Windows 7 (используя механизмы RemoteApp и Virtual PC).
Естественно, использование публикацию приложений в режиме XP Mode –временное решение, ведь тратится больше системных ресурсов, на и не все ОС поддерживаются, но, по крайней мере, возникает неких буфер времени, который позволит либо переписать ПО либо купить новые версии, поддерживающие Windows 7.
Бета версия P2V Migration for Software Assurance доступна по ссылке https://connect.microsoft.com/site14/Downloads/DownloadDetails.aspx?DownloadID=30989.
Естественно, есть некие ограничения:
— такая миграция возможна, если у вас установлена 32-битная ОС Windows XP SP3, Windows Vista Business, Windows Vista Enterprise SP1 или SP2, Windows 7;
— лицензия установленной ОС не OEM;
— жесткие диски должны быть меньше или равны 127 Гб.
Помимо этого, если в процессе установки P2V Migration не было доступа в интернет, то необходимо скачать и скопировать в установочную папку /Tools следущее ПО:

With the May 2020 Windows 7 updates, I went on a mission to determine the minimum set of updates needed to enable all features within Windows 7, including optional hotfixes, and to have the most up-to-date installation possible. After extensive testing, I concluded that 42 updates not offered through Windows Update would need to be installed to reach this objective. The following sections describe the updates required and provide links to each.
The base test image used for this research was 64-Bit Windows 7 Ultimate SP1. Microsoft Update was enabled, and all updates offered through Windows Update were installed prior to starting this investigation.
I highly recommend both the KUC Update Checker and WSUS Offline Update utilities. I used both during this investigation in order to get to this minimum required set.
Note: October 2024 was the last month Microsoft released patches for x86 versions of Windows 7. Starting November 2024, only x64 versions of the patches will be updated in this post.
Prerequisite Updates For A Clean Install
If attempting to apply ESU patches to a clean install without fully updating through Windows Update first, then these updates need to be installed and the system rebooted prior to applying any additional updates.

The next table describes the updates required to enable and patch AD LDS.
There is an issue if the AD LDS feature is installed after Windows 7 SP1. If this situation occurs, updates included within the Convenience Rollup (SP2) do not apply correctly. Therefore, these updates need to be installed manually to fully update the feature. More details can be found here.
There are a dozen different updates related to AD LDS on Windows 7 SP1. However, after careful analysis, only half of them have components not replaced by other updates. These unnecessary updates related to AD LDS are: KB2898997, KB2922852, KB3042816, KB3160352 , KB3184471, and KB3198591. The required updates are listed in the table below.
After installing the first AD LDS Update (KB975541), an update may appear as available in Windows Update (KB2853587). However, this update is not required and is replaced with KB3012660. Once KB3012660 is installed, KB2853587 will no longer appear in Windows Update.
After installing the first AD LDS Update (KB975541), another update may appear as available in Windows Update (KB3184471). However, this update is not required and is replaced with the latest ESU Windows 7 Cumulative Update. Once that is installed, KB3184471 will no longer appear in Windows Update.

Installing the Convenience Rollup (SP2) and running the System Update Readiness Tool
There are two large updates that can be applied next. The first is the Windows 7 Convenience Rollup, which is also considered SP2 for Windows 7 and includes a collection of hotfixes and updates. The second update is the System Update Readiness Tool. This update will not show as installed, so this is included to be executed once (verifying SP2 installation integrity).
After installing Service Pack 2 (KB3125574), an update may appear as available in Windows Update (KB4539601). However, this update is not required and is replaced with the latest ESU Windows 7 Cumulative Update. Once that is installed, KB4539601 will no longer appear in Windows Update.
