In Windows 10 version 2004 and every newer version, Microsoft added a new component called “Windows Feature Experience Pack”. It can be found in Settings > About and will include shell components to enable the new features faster.
At this time, the Windows 10 Settings application does not say why the "Experience Pack" is on your system. All we know is that it includes “features that are critical to the functionality of Windows.
Windows 10 is currently updated twice a year with new features or significant improvements.
That will change early next year, when Windows 10 starts getting the new features and except of traditional Windows 10 feature updates.
With the new Experience Pack, Microsoft intends to improve some features and experiences in addition to the significant Windows 10 feature updates.
Microsoft will increase the frequency of release of new features using the "Experience Pack" that will run on Windows 10 version 2004 (20H2) and any newer.
Windows updates Feature Experience Pack θα διατίθενται στους χρήστες μέσω του Windows Update, αλλά θα φτάσουν γρηγορότερα και θα έχουν μικρότερο μέγεθος. Βασικά, πρόκειται για ένα νέο channel που θα χρησιμοποιηθεί για την ενημέρωση των λειτουργιών των Windows 10 που δεν συνδέονται στενά με το λειτουργικό σύστημα.
A new package of experiences is already available to Windows Insider users with the following new features:
Screen crop enhancements: You can now use the modern Windows 10 screen crop to capture screenshots and paste them directly into a folder in File Explorer. To do this, you must press Win + Shift + S to copy your screen.
Touch keyboard: The touch keyboard now receives support for split mode on a 2-in-1 touch device.
The two new features are currently only available for Windows Insiders, but Microsoft will start promoting new experience packages to everyone from 2021.
The new feature seems to bring the new features faster, hopefully it won't cause any problems.
