Readyboot has generated low volume with two exceptions. Windows 7 hotfix resolves a condition where a computer with a large drive and a large number of system restore points, which are created after installing fixes from Windows Update for example, can cause a computer to boot without the benefit of Readyboot.
The 2nd issue is the disabling of Readyboot through improper registry changes or service start values. Remote Desktop servers and similar technologies are vulnerable to all of the root causes that can affect performance for a single user on physical hardware, plus the RDP- specific additions. Slow boots on RDP servers are fortunately rare. Troubleshooting slow boots and logons revealed the how critical WMI was to boot and logon performance.
As you can see, there are a number of root causes for slow boots and logons, including the important realization that many slow logons are actually caused by slow OS startup delaying the user logon operation. We hope this series of articles has provided compelling evidence that delayed boots and logons can result in a substantial loss of productivity and that Microsoft and its partners are continually attacking this problem through tools like XPERF, rich performance logging and most importantly, mitigation in the form of QFEs, hotfix rollups and milestone updates.
Where possible, enable automatic updates so that these fixes can get installed, otherwise, commit to testing and installing these fixes on a recurring bases. If running RTM bits of Microsoft or ISV applications, please consider the near-term testing and deployment of performance and reliability enhancing service pack and post service pack updates. Look for a reference list of fixes to attack slow boots and logons from this team in the near future.

Scheduled tasks can delay OS startup. Install KB FEP with pre engines may cause boot and logon delays. Ensure that FEP and other Microsoft security software is configured to receive monthly updates. Verbose logging enabled by "Turn on logging in Lync" can degrade system performance, especially if beta versions of Lync were installed.
Performance improvements in SEP Failure to define valid subnet, site and subnet-to-site mapping increases the probability that clients will use a remote-site DC. Logon times increased dramatically when serviced by a remote-site DC connected by a highly latent network link. See KB This problem is fixed in Windows 8 Server Beta. Windows Server Windows Server R2. User logons are fast when randomly serviced by Windows Server DCs. A failure to negotiate opportunistic locking can delay the application of policy and other files from remote servers being read in 2-byte increments until you add the BufferPolicyReads registry setting on Windows Server and XP clients explained in KB Accessing files with long file names or in long paths may generate repetitive SMB transact2 network traffic that can delay the application of computer policy, user policy, user profile load or logon script load until the Infocache registry setting is set to 10 as specified in KB Sample experience: Logons to one server take some number of seconds longer than logons on another identical server.
The inability to resolve DNS names to home directories, startup scripts, logon scripts or paths referenced in scripts can trigger long boot and logon delays. We recommend that you use fully qualified DNS names in paths for home directories, user profile, startup and logon scripts as well as paths referenced in those scripts. Yes No. Sorry this didn't help. Thanks for your feedback.

Dear All, in the last days, on several machines the logon process takes too long time. There is a way to fix this problem? Tuesday, April 1, PM.
Hi, Sorry for my late response. How is the result of the long logon process after you move to a new environment?
