HMC 4.5 Windows Update Compatibility test
On a monthly basis, the HMC test team will conduct a Windows update compatibility test (where the major roll-ups and updates will be tested) on different versions of HMC environment.
I used to provide a list of updates on this site but now all the tested hotfixes will be posted on the official Microsoft website. Please refer there instead.
