The Windows End-of-Support Solution Center is a starting point for planning your migration strategy from Windows For more information see the Microsoft Support Lifecycle Policy. After you upgrade to Windows Installer version 2. The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or the Windows Installer is not correctly installed. Contact your support personnel for assistance. The system account does not have Full permissions on a folder or registry key that the Windows Installer is trying to access.
This is NTFS-specific. If you are using Windows , make sure that SP 2 is installed. If you are using Windows NT 4. As you loop over each client it verifies if can be reloaded before attempting a navigation, which may throw an exception.
The next issue I see with the proffered code is executing this within the context of a new service worker, which must be registered first. I feel this sort of defeats the purpose of removing a service worker. To remove a bad service worker, and by this I mean remove any service worker registration, it should be handled in the client.
Now, instead of registering a new service worker you are just removing the registered service worker and not replacing it with another service worker. If you goal is to replace a service worker then you can use the activate event to trigger an update to the different clients. So the notion of a self-destructing service worker may not be the best concept to remove a service worker. I think the Gist was created more as an example of something that could be done.
It does demonstrate some important aspects of updating and removing a service worker. You will most likely need to update any live client being controlled by the service worker. This is all part of a bigger concept of service worker life cycle management. I think this is a very complex topic that is often overlooked and marginally understood. I would also like to point out how disruptive this process can be. Before automatically reloading browser tabs you should notify the user first.
Note: I have not tested this code yet. I read Arthur's blog post and wanted to update this article as a quick response. As I can over the next day or so I will test my proposal and update as needed. Hopefully you won't need to remove a service worker but bugs happen and it may be your only recourse. The code and techniques above should help get you out of the jam.
For development you probably want to use the developer tool method to unregister the service worker. But if you do ship a catastrophic bug you do have options to help your customers out. Always test your new service worker on a live, test site before shipping to production. Make sure to test on real devices too, so you know what your consumer's experience should be and to verify your changes or in this case service worker is removed.

Controls the frequency at which an event that indicates the number of successful and unsuccessful chaining attempts is logged to the System log in Event Viewer.
The default is 30 minutes. Controls the maximum number of entries that are allowed in the chaining table. If the chaining table is full and no expired entries can be removed, any incoming requests are discarded. The default value is entries. Controls the maximum number of entries that are allowed in the chaining table for a particular host. The default value is 4 entries. Specifies the smallest local clock adjustments that may be logged to the W32time service event log on the target computer.
The default value is parts per million - PPM. Indicates the maximum number of seconds a system clock can nominally hold its accuracy without synchronizing with a time source.
If this period of time passes without W32time obtaining new samples from any of its input providers, W32time initiates a rediscovery of time sources. Default: 7, seconds. Controls which events that the time service logs. Time jump 0x2. Source change The default value on domain members is 2. The default value on stand-alone clients and servers is 2. Controls the rate at which the clock is corrected.
If this value is too small, the clock is unstable and overcorrects. If the value is too large, the clock takes a long time to synchronize. The default value on domain members is 4. The default value on stand-alone clients and servers is 4. Controls the period of time for which spike detection is disabled in order to bring the local clock into synchronization quickly.
Specifies that a time offset greater than or equal to this value in 10 -7 seconds is considered a spike. Maintained by W32Time. Controls the dispersion in seconds that you must assume when the only time source is the built-in CMOS clock.
Specifies the maximum offset in seconds for which W32Time attempts to adjust the computer clock by using the clock rate. Specifies the largest negative time correction, in seconds, that the service makes. Specifies the largest interval, in log2 seconds, allowed for the system polling interval.
Specifies the largest positive time correction in seconds that the service makes. Specifies the smallest interval, in log base 2 seconds, allowed for the system polling interval. Controls the rate at which the phase error is corrected. Controls the decision to increase or decrease the poll interval for the system. Controls whether or not the DC will respond to time sync requests that use older authentication protocols. Specifies the amount of time that a suspicious offset must persist before it is accepted as correct in seconds.
An unsigned integer that indicates the time jump audit threshold, in seconds. Specifies the number of clock ticks between phase correction adjustments. Value of 1 indicates that W32Time uses multiple SSL timestamps to seed a clock that is grossly inaccurate. Indicates that non-standard mode combinations are allowed in synchronization between peers.
The default value for domain members is 1. Specifies a space-delimited list of peers from which a computer obtains time stamps, consisting of one or more DNS names or IP addresses per line. Computers connected to a domain must synchronize with a more reliable time source, such as the official U. The default value on stand-alone clients and servers is time. Indicates which peers to accept synchronization from: NoSync. The time service does not synchronize with other sources. The time service synchronizes from the servers specified in the NtpServer.
The time service synchronizes from the domain hierarchy. The time service uses all the available synchronization mechanisms. The default value on domain members is NT5DS. The default value on stand-alone clients and servers is NTP. The default value for stand-alone clients and servers is 0x Determines whether the service chooses synchronization partners outside the domain of the computer.
The default value for domain members is 2. The default value for stand-alone clients and servers is 2. Specifies the location of the DLL for the time provider. Indicates if the NtpClient provider is enabled in the current Time Service.
Specifies the events logged by the Windows Time service. Specifies the large sample skew for logging, in seconds. Specifies the maximum number of times to double the wait interval when repeated attempts to locate a peer to synchronize with fail. Specifies the initial interval to wait, in minutes, before attempting to locate a peer to synchronize with. Specifies the special poll interval, in seconds, for manual peers. Indicates that non-standard mode combinations are allowed in synchronization between clients and servers.
Indicates if the NtpServer provider is enabled in the current Time Service. Controls the number of entries created in the Windows Time log file.
