Windows 11 – previzualizarea fișierelor PDF nu funcționează în File Explorer

În Windows 11, utilizatorii pot întâmpina situația în care fișierele PDF nu sunt afișate în panoul de previzualizare din File Explorer.

La selectarea unui document PDF, panoul de previzualizare poate rămâne gol sau poate afișa mesajul „No preview available”. În unele cazuri, problema apare doar pentru anumite documente, în special pentru fișierele descărcate de pe internet. Această situație poate îngreuna identificarea rapidă a documentelor, deoarece utilizatorul trebuie să deschidă fiecare fișier separat pentru a-i verifica conținutul.

Scopul procedurii este identificarea cauzei și restabilirea previzualizării, fără dezactivarea mecanismelor de securitate ale sistemului de operare.

Tint App Icons to match your New iPhone 18 Pro Color

In iOS 26, Apple added a feature to its Home screen customization options that can match the color of your app icons with the actual color of your iPhone. The image below demonstrates the effect on last year’s iPhone 17 Pro in Cosmic Orange.

In iOS 18, Apple introduced Tinted app icons. The option applies a color filter over app icons, widgets, and even system UI elements, and with iOS 26, Apple built on the theme with a new option that matches the color of your iPhone model. This option has survived the switch to iOS 27, released on September 14, 2026, so now you can use it to match the colour of your iPhone 18 Pro, which comes in new shades of Burgundy, Silver, Glacier Blue, and Black.

iOS 27 knows the exact finish and color variant of your iPhone because Apple has the device’s SKU mapped at the firmware level (SKUs are a unique identifier that companies use to track and manage inventory). This allows iOS to identify your model and match a precise color profile.

This filter uses a base color taken from your iPhone’s chassis color, then automatically adjusts brightness, saturation, and contrast so icons remain legible while still reflecting the hardware’s tone. The following steps show you how it’s done.
