With HFNetChkLT, you can:
Scan an unlimited number of computers using the same HFNetChk engine that Shavlik licenses to Microsoft.
Create a patch download center for Operating System updates.
Push Operating System updates, including service packs, to two machines at one time using PatchPush™ technology.
Now it will identify all microsoft patches,service packs, etc... but it will only automatically deploy os patches and service packs. And really will only push 2 patches/machine at a time but it still saves time for multiple computers.
It does work very well and even identifies if you have corrupted patches. Very impressive and useful if you maintain say up to 5 pc's but it's cumbersome for more than that (but still useful).
You would probably want to purchase the pro version which will deploy ANY type of patch and will do more than 2 patches per machine at a time.
The LT version is free....check it out!
