Windows 11 requires TPM 2.0 on all devices, including virtual machines. This is because of Microsoft's insistence on making Windows more secure against hackers who expose it to vulnerabilities, but also at the expense of running on systems where virtualization-based security is enabled. At the same time, early users will notice that the new operating system from Microsoft has a common set of errors, some of which can also affect the overall performance of your PC.
Microsoft today opened the door for Windows users to upgrade to Windows 11, which offers a strange mix of various user interface improvements, new and familiar features, and pre-release features and improvements. Security has been, everyone has an old mess, the upgrade process is smoother than ever, but when you're working with Windows 11, you have to let go of your old habits and come to terms with the fact that despite Microsoft's efforts to make the user interface modern and attractive. The first is that in building Windows 11, Microsoft wanted to apply a layer of enterprise security to all devices that could run it. This has caused a great deal of controversy over the system requirements, which are much stricter than the requirements for Windows 10, and exclude many computers with relatively modern hardware.
However, if you move to Windows 11 by purchasing a new PC, game performance may decrease due to Microsoft's implementation of Virtualization Security (VBS). This was first discovered by the PC Gamer folks, who did some experiments and found that OEM hardware performed less than expected.
It appears that VBS is enabled by default on these systems, which results in a performance decline of up to 5% in Far Cry New Dawn, 10% in 3DMark Time Spy, 25% in Horizon Zero Dawn, and 28% in Shadow of the Tomb Raider. These results have been validated by ComputerBase and UL Benchmarks, the latter of which are updating benchmarking tools that take into account VBS and help users compare results fairly.
For the background, VBS is an optional feature first in Windows 10, and uses virtual machines to create and separate a secure area of memory from the normal operating system. Windows can then use this default safe mode to host various security features and prevent malware from exploiting vulnerabilities in the operating system and introducing malicious code. For corporate clients, this provides an extra layer of security.
With Windows 11, Microsoft wants to standardize VBS on consumer and enterprise/government devices. To be clear, VBS is only enabled by default on new installs. If you perform an on-site upgrade using an ISO through the Windows 11 Install Assistant, or after providing an upgrade via Windows Update, VBS will shutdown unless it was started manually before starting the upgrade process.
The second major source of annoyance for early adopters moving to Windows 11 is a set of bugs that are likely to be fixed in the coming weeks or months. Some of them are serious enough to reduce your experience, like File Explorer processing memory leaks that can quickly corrupt your RAM.
This was discovered by Reddit u/gyrohan269 a couple of months ago, but it doesn't seem to have been proven in the public release version (22000.194). Normally, File Explorer - or any other process for that matter - should free up space when it's no longer needed or the process itself is complete.
However, in Windows 11, File Explorer appears to be dedicated to almost all of your RAM when you open a new window. This means that if you are working with a large number of File Explorer windows, closing them will leave garbage in the system memory which can slow down your system when using RAM-hungry programs, be it a browser or a program. We were able to replicate this ourselves, and this can be effective, especially on cars with less than eight GB of RAM.
When typing, the only solution to this problem is to open the task manager and manually restart the File Explorer process.
Windows 11 is now available, including memory leaks and performance cuts
