Enable FIPS Mode on SLES 15 and Verify the Boot State
Follow SUSE’s SP7 procedure to enable FIPS mode, reboot safely, verify the active policy, and check whether your compliance requirement calls for validated modules.
The Reader app, developed by Microsoft, is included in the standard Windows experience, making it a handy tool for viewing various document formats such as PDF, XPS, and TIFF. Although many users rely on third-party applications for this purpose, the Reader app offers a user-friendly and integrated solution available in Windows 8.1 and Windows 10.
In Windows 8.1, the Reader app comes bundled with the operating system. Here’s how to start it:

If the Reader app is set as the default application for PDF, XPS, and TIFF files, simply double-click on the file to open it.
If you need to set the Reader app as the default for these formats, check out this guide: The easy way to set your default apps in Windows 8.1 & Windows 10.
The Reader app allows simultaneous opening of multiple documents. Here's how:
NOTE: You can only open five files at a time; exceeding this limit will close the oldest file.
If you need to view two files simultaneously, start by opening the first file. Then, right-click on it and select the "Open in a new window" option from the menu that appears.
The Microsoft Reader app offers a straightforward and effective way to manage and view your PDF, XPS, and TIFF files. With a range of functionalities, from opening multiple files to printing, this guide provides you with all the essential tips to enhance your productivity. For further information, please refer to the relevant sections in this article.
Follow SUSE’s SP7 procedure to enable FIPS mode, reboot safely, verify the active policy, and check whether your compliance requirement calls for validated modules.
Compare YaST and cryptsetup for a new encrypted SLES data volume, choose LUKS1 or LUKS2, and verify unlock and mount behavior safely.
Create, refine, and verify a least-privilege AppArmor profile on SLES 15 SP7, with a clear note on SLES 16’s SELinux default.
Set up RMT on SLES 15, mirror entitled repositories, and verify HTTPS registration and package access from a test client.
Connect SLES 15 to AD with YaST’s SSSD-based logon management, then verify directory lookup, domain login, and Kerberos tickets.
Set up the right Live Patching path for SLES 16.0 or 15 SP7, apply eligible kernel fixes, and confirm what is active without confusing it with a reboot-required kernel update.
Load a custom SLES 15 kernel module without disabling Secure Boot. Match the running kernel, sign the .ko file, enroll a MOK key, and verify loading.
SLES 15 SP5 can migrate online to SP6, but each node must reboot. Use a tested rolling upgrade or blue-green cutover to keep workloads reachable.
Use SUSE’s supported STIG profile to scan SLES 15, test remediation, review remaining findings, and retain assessment evidence.
Trace a failed Cockpit connection through DNS, port 9090, the systemd socket, firewalld, TLS, and login settings using current SUSE guidance.
