Is PCS 7 V9.0 SP2 Compatible with Windows 10 Enterprise LTSC
PCS 7 V9.0 SP2's opened manufacturer readme lists Windows 10 Enterprise 2015 LTSB 64-bit, not an interchangeable generic LTSC release. Identify the exact Windows version and station role before deciding compatibility. Do not apply claims about every V9.0 Service Pack or every Windows 7 edition to this installation. The separate XREF startup failure is not diagnosed merely by establishing the documented operating-system baseline.

What the SP2 Readme Actually Lists
The opened readme applies to PCS 7 V9.0 including SP2 and UC03. Its software requirements list Windows 10 Enterprise 2015 LTSB, 64-bit. A general Windows 10 Enterprise LTSC designation is not listed as a substitute. Siemens readme, section 3.4.1.1.
Do not rename the documented 2015 LTSB release to "LTSC 2015" when evaluating an installation.
Evaluate the Actual Station
- Record the full Windows edition, release/build and architecture.
- Identify PCS 7 Service Pack, Update Collection and the station role: ES, OS client or OS server.
- Compare the actual release with the applicable readme and its station-role compatibility table.
- Check component-specific requirements where the station uses optional software.
- Preserve the result as an explicit compatibility decision, including any unresolved requirement.
This is an engineering compatibility assessment. A product-family name or a successful setup run does not establish the complete supported configuration.
Resolve Conflicting Compatibility Claims
Broad claims that every Windows 7 edition works, or that one OS rule applies to every PCS 7 V9.0 Service Pack, are not supported by this SP2 document. It names specific Windows 7 editions, Service Packs, architectures and an English-language restriction for Professional SP1 64-bit. Readme, section 3.4.1.1.
These discrepancies should be reviewed using the exact installed release. Do not generalize another user's stability experience into a product compatibility rule or choose an old OS solely from that report.
Verification
A complete compatibility record identifies the actual Windows release, PCS 7/component versions and intended station role, together with the applicable manufacturer requirement. Resolve any mismatch before approving deployment.
The reported installation also fails to start XREF when opening its WinCC project. That error requires a separate component diagnosis; the OS compatibility answer does not establish its specific cause or repair. No installation or runtime tests were performed.
Limitations and Operational Precautions
This answer is bounded to the opened SP2/UC03 requirements. It is not an approval list for all V9.0 Service Packs or a current recommendation to deploy a historical OS.
Siemens' SP2 readme does not approve direct operating-system upgrades of the described kind. Treat a rebuild or migration as a separate controlled task, with backups, hardware/software compatibility checks and rollback. Do not change production clients merely to reproduce a reported installation problem. Readme, Notes on installing the operating system.
Engineer FAQ
Is LTSB 2015 interchangeable with any LTSC release? That interchangeability is not established by the SP2 requirements.
Are all Windows 7 versions approved? No; the document gives specific restrictions.
Does this answer repair XREF? No; it establishes the documented baseline, not a cause-specific repair.
