What changed from Windows 11 version 21H2 to Windows 11 version 22H2? Microsoft has released a detailed blog with the description of intended changes on Windows 11 version 22H2. We look at the main performance factors on Windows 11 version 22H2.

At the macro level, you need to understand that Microsoft has made changes to Windows 11 version 22H2 for enhancing performance. There are four main aspects of improvements on Windows 11 version 22H2.

  • Windows 11 version 22H2 update file has a lower size.
  • Windows 11 version 22H2 optimizes the language packs that ship with the operating system.
  • Windows 11 version 22H2 also changes that way .NET updates will be applied on the system going forward.
  • Finally, Microsoft has changed the process of rolling out the cumulative updates for Windows 11.

Reduced size of the update file

Microsoft has altered the approach towards installing the latest version of Windows 11 version 22H2. Non-system apps on Windows 11 will no longer be downloaded as part of the Windows Update process automatically.

This has been done to reduce the download size of the Windows 11 installer or update file. Microsoft has claimed that it has reduced the download size of Windows 11 version 22H2.

  • Download size of Windows 11 version 22H2 reduced by 450 MB.
  • Disk space installation requirement reduced by 399 MB in the lab. However, diagnostic data suggests that Windows 11 version 22H2 reduced installation disk requirements by up to 2.8 GB in comparison with Windows 11 21H2 version.

Lesser number of Language Packs

Windows 11 version 21H2 shipped with 110 language packs. To reduce the size of language packs, Microsoft has reduced the number of language packs in Windows 11 version 22H2 from 110 to 88 language packs. Additionally, 43 LXP that ship as part of the language packs have been removed as part of Windows 11 version 22H2 installer files.

The optimization of language packs has enabled reduction of the LXP or language packs size by 500 MB for Windows 11 version 22H2.

UUP Updates for Windows 11 version 22H2

Unified Update Platform or the UUP updates will be used for applying updates to the non-system apps and .NET framework. This reduces the size of cumulative updates that get rolled out for Windows 11.

By combining the .NET framework update through UUP, Microsoft seeks to reduce the system offline time by 30 percent. UUP updates do not lead to system restart. Therefore, .NET framework updates will not lead to system reboot. By saving the reboot instance, the system offline time will reduce.

Faster and optimized Cumulative Update Rollouts

Cumulate update process is expected to become faster and more efficient because of a couple of changes that have been introduced in the rollout process for Windows 11 version 22H2.

  • Cumulative updates, language packs and optional updates will be downloaded on a differential basis. If your system has a specific build already installed, only the incremental changes from that build will be downloaded as part of the update process.
  • Rather than downloading multiple update files, a single combined update file is downloaded as part of the cumulative updates.
  • The servicing stack update files manage the update cache files and store the cumulative update files. Efficient caching of the cumulative update files help in prevent download of cumulative updates on multiple times.

So, what do we gain with the revised update process and for Windows 11 version 22H2.

Performance Gains from Windows 11 version 22H2

There are some measurable gains that can be attributed to Microsoft’s revised approach towards updating to Windows 11 version 22H2.

  • There has been a reduction in disk space requirements for Windows 11 version 22H2.
  • The process of rolling out cumulative updates is faster.
  • Installation or update to Windows 11 version 22H2 will take lesser time.
  • There has been a reduction in the offline time for systems in Windows 11 version 22H2.
