I am presently using Win7 Ult. I have run Win Updates, qualified for the Win10 download, did the download and backed up my Win7 install. When I try to do the Win10 update I get the dialog "Infineon TPM Professional Package is not compatible with Win10. It must be uninstalled." I have the 1.2 module with the v3.6.000 package. There is supposedly a v4.3 package available. It is supposed to be for Win7 and the Win8 flavors. I have not figured out how to get my hands on it yet. Will that version make my module compatible with Win10? Are they just slow in getting updated drivers out? Or, am I going to loose my BitLocker TPM? Is the Pro Pkg even needed with Win10? Anyone with knowledge about this? EDIT: I found a copy of the v4.3 update package that I could install on my PC. It is installed. It is compatible with Win10. I am clear to install the Win10 update now.
