Download Windows Updates
Use the Download Updates feature to gather and maintain Windows updates with ease.
The Download Updates feature helps you gather and maintain Windows updates with ease and reliability. Access it via the toolbar under Start → Tools, or the Updates page → Add → Latest online updates.
Key Features
- Downloads the latest updates directly from Microsoft servers
- Verifies downloaded update file hashes
- Resumes interrupted downloads
- Organizes downloaded updates per Windows version
- Labels updates to help with pre-selection of recommended ones
- Multi-threaded download and hashing
Update lists are manually curated and usually updated within a few hours of release. While lists come from the NTLite server, actual updates are downloaded only from Microsoft's servers.

Update Cache
Before using the Downloader, set your preferred download location under File → Settings → Update Cache directory.
You can use subfolders to organize updates. Update files can be renamed and are still properly detected. Example subdirectory names: 10.0.1803.x64, 10.0.1607.x86, 6.3.U3.x64, 6.1.SP1.x86
Operations
Verify
If there are pre-existing updates in the Update Cache folder, use Verify first. This triggers a hash check to detect incomplete downloads and corrupted files. Only updates from the online list support verification.
Enqueue
Adds updates to the Updates → Integration Queue for integration to the loaded image. First load a target on the Source page to enable this. Non-existing updates will be automatically downloaded before integration when Apply → Process starts.
Download
Pre-downloads selected non-existing updates without integrating them.
Trim
To easily delete unlisted and obsolete updates from the Update Cache, use File → Settings → Update Cache Trim.
