### ❌ Actual phrase(s)

PowerToys version: 0.99.1
Windows language: Swedish

In the Swedish localization:
1. The category "System Tools" is displayed in English instead of Swedish.
Suggested translation: Systemverktyg
(as that is the standard translation in the Swedish version of Windows)

2. The System Tool option "Awake" is displayed in English instead of Swedish.
Suggested translation: Vakenläge

3. The System Tool option "Light Switch" is translated as "Ljusbrytare", which is unclear and uninformative.
Suggested new translation: Temaväxlaren

4. The System Tool option "PowerToys Run" is displayed in English instead of Swedish.
Suggested translation: PowerToys Kör
(as "Run" is translated to "Kör" in the Swedish version of Windows)

5. The category "Windowing & Layouts" is translated as "Fönster och layouter", which could be clearer.
Suggested translation: Fönsterhantering & layouter

6. The Windowing & Layouts option "Grab And Move" is translated as "Ta tag i och flytta", which is descriptive but could be improved.
Suggested translation: Greppa och flytta

7. The category "Input & Output" is translated as "Indata/utdata", which doesn’t follow any established naming convention.
Suggested translation: Indata & utdata

8. The Input & Output option "Power Display" is translated as "Energisparläge", which is incorrect and misleading.
Suggested translation: Skärmhanteraren

9. The Input & Output option "Quick Accent" is translated as "Snabb Accent", which is descriptive but should be written as a proper Swedish compound word.
Suggested translation: Snabbaccent

10. The File Manager option "File Explorer Add-ons" is translated as "Utforskaren tillägg", which is somewhat descriptive but incorrect Swedish. The correct wording should have been "Utforskarens tillägg" though it could still be improved.
Suggested translation: Utforskartillägg
Alternative translation: Utforskarens tillägg
