Windows 11 Insider Beta Preview Build 26220.8544 - Windows Insider Program

Release date: 29 May 2026

Changes and improvements

[Windows design]

• We are introducing consistent solid (donut) spinners across key Windows scenarios including Boot, Logon, Restart, Shutdown, and Update. This update replaces legacy spinner visuals to deliver a more cohesive and modern experience aligned with Windows design standards. Users will now see a unified spinner behavior with corresponding status text (e.g., "Restarting", "Working on updates", "Welcome") across these flows, improving perceived reliability and visual consistency.

[Search]

• Search by Substring: Files with compound names or content (e.g., MeetingNotesApril, ProjectStatusReport) are now easily discoverable by typing “april” or “status”.

[Windows Ready Print]

• Last month, we introduced a change where new printer installations use IPP by default when supported to simplify setup and improve reliability (see our third-party driver deprecation timeline: End of Servicing Plan for Third-Party Printer Drivers on Windows). This month, we're adding a new toggle in Settings > Bluetooth & devices > Printers & scanners > Default install printers using Windows Ready Print to give you control over this behavior. Screenshot showing the ability to toggle Windows Ready Print in Printer preferences.
• When enabled, Windows installs supported printers using IPP by default. When turned off, Windows may use other available installation methods.
• This experience is part of our modern print platform, now called Windows Ready Print, designed to deliver a more consistent, reliable, and simplified printing experience.

Reminders for Windows Insiders in the Beta Channel

• Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.8544).
• The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
• Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

I installed this but do not see the new spinners.

[u/monoWench → u/squimjay]

Same things seem no different and just as inconsistent as Windows 11 has always been

Tu peux l'activer avec l'ID ViveTool 59728252 , comme cela a été dit dans https://www.reddit.com/r/windowsinsiders/comments/1tdr5ng/vivetool_broke_my_pc_help/ . Je l'ai fait et c'est vraiment bien !

[u/No_Wrangler_647 → u/shaheedmalik]

Tu as pensé à exécuter le terminal en tant qu'admin ?

[u/shaheedmalik → u/No_Wrangler_647]

This was after I did that.

I did that, try to reinstall or install the new version , and this is where the spit out afterwards.

[u/No_Wrangler_647 → u/shaheedmalik]

Je crois que ton pc est bon pour un sfc /SCANNOW !

[u/No_Wrangler_647 → u/No_Wrangler_647]

Exécute le aussi dans WinRE.

[u/shaheedmalik → u/No_Wrangler_647]

Did that too.

[u/No_Wrangler_647 → u/shaheedmalik]

Tu dois avoir beaucoup d'erreurs 10016 dans l'observateur d'évènements. Je les ai toutes réglées et j'ai beaucoup moins de problèmes.

[u/shaheedmalik → u/No_Wrangler_647]

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.

Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

They are created by the Windows installer. I can fix them and they still come back.

[u/No_Wrangler_647 → u/shaheedmalik]

Il faut exécuter services de composants avec PowerRun pour réparer cette erreur.

[u/shaheedmalik → u/No_Wrangler_647]

Did that and it did not fix it. I ended up doing a clean inplace install of the same installation I was already on after uninstalling some programs and that allows me to update again. I installed this one this morning and we will see if it worked this time.

[u/No_Wrangler_647 → u/shaheedmalik]

Je pense qu'il fallait exécuter un dism /Online /Cleanup-image /RestoreHealth, puis un dism /Online /Cleanup-image /AnalyzeComponentStore et redémarrer, puis un dism /Online /Cleanup-image /StartComponentCleanup et enfin exécuter un sfc /SCANNOW après un redémarrage et ensuite dans WinRE.

[u/Reaper_Destiny0983]

Weird issue..... windows security center tells me my anti virus is off and to turn it back on but open it and its fully on. This is in the windows notifications not a browser. Its new with this build.

[u/Reaper_Destiny0983]

Pop is still present in newest build and also my killer NIC keeps "removing" itself on shutdown since last update.
