Microsoft released an XL-sized bundle of security fixes for its products for this month's Patch Tuesday, and other vendors are close behind in issuing updates.
The Windows goliath's batch for July has 117 patches, 13 for what's said to be critical bugs, 103 important, and one moderate.
Some infosec bods claimed they can bypass the patch, though Microsoft said that isn't possible provided your Registry keys are certain values.
Microsoft said a system with this patch installed is, by default, not vulnerable to Printnightmare though it's been suggested there are a number of ways to make a box vulnerable.
There are then notable patches for HEVC Video Extensions, Microsoft Excel and SharePoint Server, Word, Power BI... the list is huge.
Other vendors are riding the Patch Tuesday train with Microsoft.
