Microsoft is in the process of bringing an extended feature for Windows 11 that allows users to uninstall more built-in apps. These applications, commonly referred to as “inbox apps,” are pre-installed by default on Windows 11 devices. The new feature is currently being tested with users in the Canary Channel. So the users who have updated to Windows 11 Insider Build 25931 can use this option.

The apps that can be removed include the Camera app, the recently discontinued Cortana app, the Photos app, the People app, and the Remote Desktop (MSTSC) client.

Uninstall in built apps Windows 11

Uninstall in built apps Windows 11

While each individual built-in app might not consume a substantial amount of storage space, the option to uninstall them collectively contributes to a potentially leaner operating system environment. This aligns with Microsoft’s approach of allowing users to declutter their systems from apps they do not require, thus offering a more tailored user experience.

The initiative began earlier this year with the introduction of the Camera app’s uninstallation option in March. More recently, the option to uninstall the Cortana app was added in test builds, highlighting Microsoft’s commitment to refining the Windows 11 experience based on user feedback. However, users who are not currently on Windows Insider builds will have to wait until these enhanced uninstallation capabilities are widely accessible.

Microsoft’s upcoming major Windows 11 update, scheduled for release in September, is anticipated to introduce even more options for users to uninstall built-in apps.

Killexams : Microsoft 365 Copilot: Release date, features and pricing
microsoft 365 copilot hero


Microsoft 365 Copilot is one of the many AI products in development by the Redmond firm. Announced in March 2023, the product is yet to roll out, but its touted capabilities hint at providing a more cohesive office suite to businesses. But when is the Microsoft 365 Copilot release date, and can you join the Early Access Program? Here’s what you need to know.

When will Microsoft 365 Copilot be available?

Although it’s been a few months since Microsoft announced Copilot, it hasn’t yet set an official Copilot release date. As of August 2023, the program is still in its Early Access Program phase, with only a handful of trusted companies and users test-driving the product. Considering the small demo size, it could be a while before the feature reaches public customers.

Can I join the Microsoft 365 Copilot Early Access Program?

Unlike Bing Chat, Microsoft’s 365 Copilot Early Access Program is closed to the general public. The feature is only available to a select number (around 600 as of August 2023) of trusted testers. This means you cannot sign up to test Copilot.

Microsoft 365 Copilot features

On paper, Microsoft 365 Copilot is an exciting prospect for office workers. In brief, Copilot can be viewed as a more extensive and capable version of Microsoft’s original Office helper, Clippy. But unlike Clippy’s severely limited feature kit, Copilot uses generative AI to assist users with documents, spreadsheets, presentations, and more.

Here’s a brief look at what  Copilot brings to some of the 365 products:

  • Outlook: Microsoft notes that Copilot can help users manage their inboxes more efficiently. More specifically, it claims it’ll allow you to clear your inbox “in minutes, not hours.”
  • Excel: Based on preview videos, you can ask Copilot to analyze data in spreadsheets to seek out trends, and create visualizations of said data.
  • PowerPoint: Create presentations based on a prompt. For instance, users can create an entire slideshow by referring to details in a product guide.
  • Word: Word makes full use of Copilot’s GPT-4 roots. Microsoft notes that you can create first drafts using a prompt, which could save hours. Users can then accept the draft, modify it, and more.

Microsoft is also rolling out Copilot in the form of Business Chat, which works across the umbrella of 365 apps.

Is Microsoft 365 Copilot free?

Microsoft 365 Copilot is not free, and it’s unclear if a free tier will ever be available.

When Copilot launches, those looking to adopt Microsoft’s new AI Office future must spend $30 per user per month. Notably, that’s more expensive than the Microsoft 365 Business Premium tier, which demands $22 per user monthly.

Copilot will be available through Microsoft 365’s Enterprise-level E3 and E5 tiers, alongside Business Standard and Business Premium offerings.

Notably, the Copilot moniker is coming to other Microsoft properties in the future. The company has plans for Windows Copilot — a similar feature built into Windows 11. As a result, the feature can effectively double as a system manager, opening files, controlling apps, and adjusting system settings. Announced in June 2023, it’s currently in beta, so you’ll need to be part of the Insider Preview updates channel to try it out.

Sun, 30 Jul 2023 05:56:00 -0500 en-US text/html Killexams : Microsoft Stipulates Account Requirement for 'Personal Use' of … –

Advanced Search
Microsoft indicated in a Thursday announcement that it will require the use of Microsoft Accounts (MSAs) for "personal use" of the Windows 11 Pro edition operating system on initial setup.
The MSA requirement won’t apply to users of the Windows 11 Pro edition for work or school purposes, Microsoft promised. Here’s Microsoft statement to that effect:
Previously, we shared new requirements for internet and MSA on the Windows 11 Pro edition. Today, Windows Insiders on Windows 11 Pro edition will now require MSA and internet connectivity during the initial device setup (OOBE) only when setting up for personal use. If you choose to setup device for Work or School, there is no change, and it will work the same way as before.
This announcement was aimed at Windows Insider Program OS test participants. It described new features in Windows 11 preview build 22616. For instance, Microsoft highlighted a new "controller bar" feature that lets PC users quickly access their games.
MSA Currently Required for Home Edition
Possibly, the announcement of an MSA requirement for Windows 11 Pro edition personal users doesn’t just apply to Windows Insider Program testers, but also will apply more broadly to future purchasers of the Windows 11 Pro edition product.
At present, an MSA was only listed as a requirement for Windows 11 Home edition users, per Microsoft’s Windows 11 requirements page.
The timing for this suggested policy change for personal users of the Windows 11 Pro edition wasn’t indicated in the announcement. It possibly just applies to new PC setups. How it might affect current Windows 11 Pro edition users wasn’t described.
Microsoft’s Thursday announcement was kind of a clarification of its announcement back in February. Many observers interpreted that February announcement as saying that all Windows 11 Pro edition users would require an MSA on initial PC setup, even though Microsoft did state at the time that it intended its policy change to apply to "personal use" cases.
Local Account vs. MSA
Individuals may have wanted to set up a Windows 11 Pro PC using a "local account" instead of an MSA because of uncertainty about privacy issues when agreeing to use an MSA.
User of MSAs must agree that Microsoft can collect certain personal information. That information includes "credentials, name and contact data, payment data, device and usage data, your contacts, information about your activities, and your interests and favorites," according to Microsoft’s "Privacy Statement" document.
There are some good reasons to use MSAs. For instance, MSAs support multifactor authentication for identity access security. It’s easier to synchronize with Microsoft’s services, including syncing files with OneDrive across multiple devices.
Based on Microsoft’s announcement, though, it appears that all personal users of Windows 11 will be required to use MSAs on initial PC setup.
For business and educational organizations, Microsoft’s Windows 11 Pro edition policy clarification likely eases matters, especially for IT pros having to provision multiple PCs. They won’t have to use MSAs when provisioning them, for instance.

Killexams : Big Tech Earnings Will Test Investors’ Fervor for A.I.

Nasdaq futures are up on Tuesday morning, ahead of a Big Tech earnings bonanza that kicks off when Microsoft and Alphabet report second-quarter results after the closing bell. One question is at the top of many investors’ minds: Is the hype around artificial intelligence, which has propelled tech giants’ stock prices sky-high in exact months, justified, or is it another bubble in the making?

Wall Street is deeply divided about the A.I. rally. Mike Wilson, Morgan Stanley’s chief U.S. equity strategist, apologized to clients on Monday, writing that his pessimistic stock market calls failed to spot the surge in A.I.-related stocks. (The chip maker Nvidia, for example, has seen its stock triple in value since January.) And analysts at Citigroup are sticking to their bullish thesis for such companies.

On the other hand, Marko Kolanovic, JPMorgan Chase’s chief market strategist, is unconvinced that tech fervor will help the markets avoid a sharp decline this year.

All eyes will be on Microsoft and Alphabet, which are at the forefront of commercializing generative A.I., the technology behind chatbots like ChatGPT that have captured the public’s imagination. Both are incorporating A.I. into a wide array of their products, with Microsoft — which has invested billions in OpenAI — hoping that the technology can help it gain ground on Google in key businesses like search.

Meta’s turn is Wednesday. The parent company of Facebook and Instagram is also betting big on the technology, including by making the code for its most advanced A.I. project free for public use. (Analysts also want to know more about how Meta plans to make money from Threads, its new rival to Twitter, the company rebranded as X.)

Macroeconomic factors are still weighing on these companies. Inflation and an uncertain outlook hit them hard last year, as customers cut back on buying software and spending on advertising, spurring them to lay off thousands of workers.

Recent data shows that inflation has begun to moderate, lifting these stocks in exact weeks, but investors will want to see proof that the sector is through the worst of it. The Fed is widely expected to increase interest rates by a quarter percentage point at its rate-setting meeting on Wednesday, but Wall Street isn’t sure whether the central bank will stop there or continue raising borrowing costs and risk a recession.

And it won’t just come down to tech stocks. This is the busiest week of the current earnings season, with 39 percent of S&P 500 firms announcing results. The next few days will provide an important look at the overall health of corporate America. Consumer bellwethers including Coca-Cola and McDonald’s and industrial titans like Boeing will be reporting.

Unilever says that inflation has peaked. Shares in the consumer goods giant rallied on Tuesday morning after it reported a strong second-half sales outlook, with the company forecasting that slowing price increases will translate to higher consumer purchases. But it warned that the war in Ukraine could send agricultural commodity prices higher, raising costs.

UBS agrees to $387 million in fines over Credit Suisse missteps. UBS reached a deal with U.S. and British regulators to resolve inquiries into the oversight failures that led to Credit Suisse losing $5.5 billion in the collapse of the investment firm Archegos in 2021. UBS bought its ailing rival this year, inheriting its thicket of legal troubles.

Senators cast new scrutiny over Leon Black’s ties to Jeffrey Epstein. The Senate Finance Committee is investigating whether a $158 million payout from Mr. Black to the disgraced financier for tax and estate planning services was part of a tax-avoidance scheme, The Times reports. Separately, the U.S. Virgin Islands accused JPMorgan Chase of reimbursing a former executive, Jes Staley, for trips to meet Epstein.

The I.R.S. ends surprise visits to homes and businesses. The agency said that it would stop the practice, which was a mainstay of efforts to collect unpaid taxes. The move comes as the I.R.S. rethinks its operations, and faces increased political scrutiny by Republicans and threats to its employees.

The U.S. reportedly scrutinizes Abu Dhabi’s takeover bid for Fortress Investment Group. The Committee on Foreign Investment in the United States is examining whether the $3 billion deal by Mubadala, an Emirati sovereign wealth fund, poses national security concerns, according to The Financial Times. At issue are the United Arab Emirates’ ties to China.

Cryptocurrencies and climate change have been linked as issues before in terms of how carbon-intensive it is to produce new digital tokens. But the crypto industry is also hoping to piggyback off a legal doctrine at the heart of a Supreme Court decision involving the Environmental Protection Agency last year.

Coinbase is seizing on an E.P.A. loss as a legal defense. Last summer, the Supreme Court struck down an emissions rule by the environmental agency, citing the so-called major questions doctrine, a principle asserting that Congress hasn’t given regulators power to decide significant political or economic issues on their own.

Now, Coinbase is arguing that the S.E.C. can’t prosecute it because it lacks the power to regulate crypto. Moreover, the exchange says, Congress is actively working on legislation to oversee its industry. “It’s never been clearer that the Supreme Court has particular focus on major questions and the role of regulators in our economy,” Paul Grewal, Coinbase’s chief legal officer, told DealBook.

The S.E.C. counters that Coinbase is missing the point. Agency lawyers wrote in a exact court filing that the E.P.A. case was about rule-making, not the regulator’s power to prosecute. Critics add that it’s not clear that regulating crypto counts as a major-question issue, given that the industry’s total market capitalization is less than that of Apple, Microsoft or Alphabet.

Business advocates appear undeterred by those arguments. “The major questions doctrine seems built for crypto at this moment,” Katie Haun, the crypto investor and former federal prosecutor, tweeted recently.

Separately, the U.S. Chamber of Commerce, which represents businesses more broadly, has expressed eagerness to use major-questions arguments in court to limit the power of a proposed Federal Trade Commission ban on noncompete clauses.

Led by “Barbie” and “Oppenheimer,” the North American box office had its biggest weekend since 2019 and its fourth-best ever. Here’s how the phenomenon stacks up to other weekend performances, which were each dominated by a single blockbuster.

Though Elon Musk’s rebranding of Twitter as X came as a surprise over the weekend, the abrupt name change is playing about as well as could have been expected these days. Users and advertisers were divided on the wisdom of the move, which eliminated the company’s longtime bird logo, even if pulling down the old signage ran into some hiccups.

The change was reflected at Twitter’s headquarters immediately. Inside the San Francisco office, X logos were projected in the cafeteria, while conference rooms were renamed with words including “eXposure” and “s3Xy,” according to The Times.

But efforts to remove the Twitter name from the building encountered difficulties, when the San Francisco Police Department stopped workers for performing “unauthorized work.” As of this morning, the letters “er” remain visible from the street.

People can’t agree on whether the move will cost the company dearly. Skeptics said ditching the Twitter name and famous bird logo — which Twitter once identified as among its most recognizable assets — could cost as much as $20 billion in value. (Among them: Esther Crawford, the former Twitter executive who was briefly among Mr. Musk’s top lieutenants.) Some users bemoaned the switch to the more generic-sounding X.

Others said that the rebranding could help the company shed years of baggage associated with the Twitter name, a line of thought shared by none other than Jack Dorsey, the company’s co-founder. Some ad executives said that the change wouldn’t meaningfully drive away potential advertisers, while others said that Musk had at least succeeded in drumming up publicity for his platform after Meta’s Threads made a splashy debut.

Speaking of Meta … the Facebook parent company owns an X trademark with regards to social networking, though it relates to a specific blue-and-white logo. Mr. Musk’s company now uses a black-and-white mark, though trademark lawyers said the reliance on a simple letter almost certainly invited legal challenges.
